Report Highlights
The term "communications
processor" describes not only a specific category of equipment but also
systems that perform communications processing functions and other
services. Datapro's definition of
communications processors covers
multifunctional, intelligent systems
dedicated to communications and
serving as nodes in a network. These
systems generally include three basic
types of products: front-end processors, intelligent switches, and remote
concentrators.
In the late 1970s, IBM's SNA and
the ISO's OSI model advanced data
communications as a function separate from applications processing.
SNA and OSI defined a network as a

physical entity, separate from its participating hosts and terminals. The
implementation of a physically separate communications function occurred through a system of small
dedicated computers. Users placed
these communications processors at
the front end of a mainframe or allowed them to function independently as concentrators and switches
within their architectures.
In most communications processors,
under the direction of the CPU,
some components perform functions
for the whole communications processor, while others perform functions for specific groups of lines.
Among the former are host interfaces, input/output (110) processors,
reference clocks, and operator interfaces. Among the latter are the processor's line bases and line sets.
There are two kinds of network architectures: those for communications among computers and
terminals from a specific vendor,
and those for open communications
regardless of the vendor of the communicating devices.
This report discusses communications processor design, evolution,
and position in modern network architectures. It concludes with Selection Guidelines for users.

distributed applications processors; gathers,
queues, and multiplexes their transmissions onto
one or more high-speed network trunks; and participates in the network's control and management,
either under the direction of a master processor or
as a peer of other concentrators and switches.
Network Architectures

Technology Basics
The definition of a communications processor varies greatly. Network designers hold one view of
what a communications processor does, but equipment manufacturers hold another. The term "communications processor" has covered equipment
ranging from an IBM 3745 to a four-port packet
assembler/disassembler (PAD).
A network designer believes that a communications processor should set up connections to
transmit and receive data, mUltiplex and demultiplex data, frame and unframe messages, perform
error correction and protocol conversion, choose
transmission routes, and collect performance and
traffic statistics. Unfortunately, this definition has
led many manufacturers to classify their protocol
converters, PADs, terminal controllers, and multiplexers as communications processors. Manufacturers consider communications processors as
devices that connect terminals to networks and
maintain control through changing network conditions. This concept clouds the definition of the
equipment-an IBM 3745 and a protocol converter do not belong in the same category.
Datapro defines a communications processor
as a multifunctional, intelligent device dedicated to
communications and serving as a control point, or
node, in a data communications network. It functions as a front end to a mainframe, as an intelligent switch, or as a remote concentrator. As a
front-end processor (FEP), the communications
processor acts as a peripheral device locally attached to one or more large computers, relieving
them of the overhead involved in message handling and network control. An intelligent switch
routes messages among the network's various end
points and participates in the network's control
and management, either under the control of a
master (usually front-end) processor oras a peer of
other intelligent switches. A concentrator controls a,
community of terminals, clusters of terminals, or
MAY 1991

In general, there are two kinds of network architectures: those designed to provide communications
among computers and terminals from a specific
vendor, and those designed to provide open communications regardless of the vendor of the communicating devices.
Mainframe vendor architectures include
IBM's SNA, Bull's DSA, and Unisys' BNA and
DCA. Open architectures include the CCITT X.25
packet-switching specification and several
"transparent" network schemes marketed by communications vendors. The communications processor plays an important part in vendor-specific and
open architectures. The International Organization
for Standardization (ISO) reference model for
Open Systems Interconnection (OSI) provides a
framework in which to examine the functions performed by communications processors in different
kinds of network architectures.
Mainframe Architectures
In network architectures designed by mainframe
vendors, the communications processor functions
most often as a front end and controls communications in conjunction with one or more software
systems in the host computer. In general, the frontend processor handles the Data Link through Session layers of the ISO model, with host software
implementing the Presentation and Application
layers. The activity in the layers varies, depending
on the architecture. In Unisys' DCA, the DCPSeries front end controls many Presentation layer
functions, while in IBM's SNA, the host's access
method (along with software residing in the terminal controllers) handles communications down to
the Session layer, with the 37XX front end acting
almost as a channel-attached packet switch. The
range of control assigned to front-end processors in
other mainframe architectures varies between
those extremes.
In all mainframe architectures, the same communications processor models that serve as front
ends also function as intelligent switches and as

remote concentrators. In these functions, the communications processors usually appear in smaller
configurations than they do as front ends. Communications processors working in mainframe architectures also perform intelligent gateway functions.
In this application, the communications processor
provides the interface between the mainframe network and communications facilities outside the
architecture, particularly public, packet switched
data networks using X.25 protocols.

(

Open Architectures
In an open architecture, such as X.25, the communications processor serves as an intelligent packet
switch, implementing the Data Link through
Transport layers via a uniform set of complementary protocols. Designed specifically for public
data networks, X.25 protocols establish virtual circuits, or logical paths through the network, for devices from any vendor. Communicating devices at

either end of the virtual circuit must handle the
Session, Presentation, and Application layers according to their own protocols.
In a public network, the network provider is
responsible for network management. The X.25
communications processors in such a network,
therefore, carry a heavy load of access, error, and
class-of-service control, along with provisions for
statistically recording traffic and usage data for
individual users.
Communications processors operating in fullscale X.25 configurations seldom perform gateway
functions. The user must comply with the network's protocols, either through X.25 software residing in a participating host or its front-end
processor, or through a packet assembler/
disassembler (PAD) that handles the Physical and
Data Link layers of the architecture.
Vendors offer transparent architectures as
low-cost alternatives to mainframe architectures

Processors

and X.25 implementations. These architectures are
usually stripped-down versions ofX.25 without the
network administration and class-of-service overhead necessary to operate a public or large private
network. In these architectures, the communications processor functions primarily as a switching
concentrator, providing services at the Data Link,
Network, and Transport layers. Most of these concentrators evolved at the high ends oflines of statistical multiplexers, adding the crucial routing and
flow control features that qualify them as communications processors. Some of these products offer
integrated network management functions, such as
error logging and performance statistics, but most
rely on separate, complementary network management systems for these functions.
Evolution of the Communications Processor

Two developments in the late 1960s provided the
technical base for the modern communications
processor: the minicomputer and ARPAnet. The
minicomputer performed a number of functions
more efficiently than a mainframe and supplied
the bus architecture that gave communications
processors modularity and flexibility. ARPAnet,
the first large-scale packet switched data network,
produced the fundamental design principles for
current data communications architectures. From
these principles originated the intelligent virtual
circuit switch, the first functional communications
processor.
A later development in minicomputer applications created the distributed processor, a small
computer dedicated to part of a larger application
that performed communications with its peers in a
distributed network. Distributed processing contributed the idea of intelligent communications
handling under software control.
The lower cost of dedicated processing in
small computers made feasible the idea of dedicating a small computer to off-load intelligent communications handling from the mainframe. The
first intelligent front ends, such as IBM's 3704,
predate modern network architectures and, to a
large extent, made such architectures possible.
The microprocessor also contributed to the
development of the communications processor.
The advent of inexpensive silicon intelligence enabled designers to implement the hierarchical
scheme of the typical communications architecture

in hardware, with dedicated microprocessors performing low-level functions and reporting to larger,
more complex processors at higher levels. Indeed,
some line bases in present-day communications
processors are programmable, receiving downloads
from the units' CPUs that describe protocol and
synchronization. Some systems comprise entirely
redundant, microprocessor-controlled modules
that perform the functions of other modules, using
the proper software load.

Products
Front-end processing is the most difficult task performed by a communications processor. In a large,
complex network governed by one or more mainframe hosts, a front end must perform the follow- .
ing: physical transmission and reception of data;
data buffering and queuing; multiplexing; message
framing and unframing; control transmission errors; message sequencing; protocol conversion;
message pacing and flow control; message or
packet assembly and disassembly; route selection;
session establishment and disconnection; and data
formatting.
Intelligent switching is slightly less complex.
When acting as a dedicated switch, the communications processor does not carry on a running dialog with a host computer and is not responsible for
end-to-end establishment and disconnection of sessions. Still, an intelligent switch in normal operation must perform several basic functions.
Since concentration is the simplest task performed by a communications processor, it can be
confused with less sophisticated, single-function
devices like statistical multiplexers, protocol converters, PADs, and terminal cluster controllers.
Indeed, the widespread use of microprocessors and
the declining cost of silicon intelligence, have enabled many devices at the high ends of these lines
to approach the functions of true communications
processors. In true communications processing like
concentration, however, a dynamic process occurs
that involves feedback from other intelligent devices in the network. Statistical multiplexing, protocol conversion, and packet assembly/disassembly
are basically static processes that do not change as
conditions change in the network.
An intelligent concentrator participates in the
control of the network, either under the direction

of a master processor or as a peer of other concentrators and switches, receiving status information
from the network and changing its behavior accordingly. These changes include accelerating or
withholding transmissions, initiating diagnostic
procedures for pathways and devices in its local
domain, and controlling access to the network
from its locally attached devices. Some sophisticated terminal controllers, notably IBM's 317 4s,

perform some or all of these functions.
Design

(

The basic design of almost all communications
processors follows a three-tiered, hierarchical
plan-a plan that they share in common with digital PBXs and with a number of other data communications components.
The device's central processing unit (CPU)
with its main memory sits at the top of the hierarchy. The CPU controls the communications processor's operation according to the rules and
parameters of its operating software and, in frontend configurations, in conjunction with instructions from the host computer. In general, the CPU
performs addressing, route selection, protocol conversion, access control, session establishment,

application-level formatting, and error logging. It
also delegates rote operations to subsidiary components.

Input/Output Processors: Some communications
processors contain one or more input/output processors that transfer data between the CPU and
attached storage peripherals. In some cases, the I/O
processors arbitrate among the various line bases
for access to main memory and to the CPU, handling interrupts generated by the line bases or host

interfaces to gain the attention of the CPU, or controlling the line bases' and host interfaces' access to
main memory. In communications processors with
more than one 1/0 processor, each 1/0 processor
usually controls a set complement of storage units
or communications lines.

Reference Clock: The reference clock generates a
timing signal for other components of the communications processor. In many systems, the CPU
performs reference timing. Some systems have separate reference clocks for timing signals at different
data rates.

the same data tate. The line set handles serialization of data and interface-level control signaling.

-"'

Parallel Data Bus: All components of the communications processor communicate with one another
over a parallel data bus, usually located along the
backplane or a side plane of the processor's cabinet. The physical bus architecture, popularized by
minicomputer design, supports easy installation
and replacement of parts. In a hierarchical architecture, the bus also accommodates easy reconfiguration. To replace asynchronous communications
over voice grade lines with HDLC communications over wideband or satellite circuits for a 16line segment of a network, a user might need only
to replace one line base and eight line sets, rather
than swapping out an entire front-end processor.
The hierarchical design extends the communications processor's functionality over time and helps.
to protect the user's investment. Figure 2 shows the
hierarchical configuration of a generalized communications processor.

Selection Guidelines

Line Bases and Line Sets: All of the aforementioned devices perform functions that are shared
among all communications lines; they sit just below the CPU in the communications processor's
internal hierarchy. On the network side, the "business end" of a communications processor, the line
bases and line sets complete the hierarchy.
A line base, sometimes called an attachment
base, interface base, or interface module, handles
communications atthe Data Link layer between
the communications processor and a group of attached communications lines that share a common
synchronization pattern, line speed, and (sometimes) protocol. Each line base usually contains a
dedicated microprocessor that performs framing
and stripping, message buffering, message sequencing, synchronization, and error detection under the
direction of the CPU. Most current communications processors accommodate from 8 to 32 line
bases, each of which handles from two to eight line
sets.
A line set handles communications at the
Physical layer between its attached line base and
from one to eight communications lines. All the
communications lines attached to a line set must
use the same physical interface at approximately

MAY 1991

The principal advantage of a communications processor as a networking tool is the physical and logical separation of the networking function from the
applications of its end users. Whatever its architecture, such a network functions for any application,
grows in size without qualitative change to accommodate new applications, and runs new applications through the installation of relatively
standard, intelligent components. The user need
not redesign and rebuild a modular network to
change the network's ultimate purpose.
Programmable, software-controlled communications processors are especially useful tools in
standalone networks because they accommodate
not only changes in application but also the effects
of technical progress. A software-controlled communications processor with a good design can survive breakthroughs in networking techniques
through relatively simple upgrades. The
microprocessor-controlled line bases, and even line
sets, provide an even more flexible buffer against
obsolescence.
In operation, a network controlled by communications processors survives the total failure of
one or more of its host processors. In a multihost
network, front-end processors switch users from

applications in a failed host to similar or identical
applications in a backup host, perhaps elsewhere
on the network. In a single-host network, a functioning front end allows service to degrade gracefully in the event of a host failure, sometimes
allowing users to terminate their tasks before total
system failure or allowing communications among
distributed application processors in the absence of
the controlling host.
The communications processor still fulfills its
original purpose: relieving the host of the overhead
generated by keeping track of a network. Today's
networks are orders of magnitude more complex
than those of the mid-1970s when the first communications processors appeared. Thanks to the declining costs of memory and processing power,

many oftoday's communications processors are
faster and more powerful than mainframes of that
era.
The complexity of communications processors, however, poses problems. In an era of userfriendly hardware and software, the
communications processor remains a device hospitable only to trained engineers. Most require programs written in an arcane, Assembler-level
language, sometimes (but not always) with the benefit of pregenerated macros in the host access
method.•

Report Highlights
The term "communications
processor" describes not only a specific category of equipment, but also
systems that perform communications processing functions and other
services. Datapro's definition of
communications processors covers
multifunctional, intelligent systems
dedicated to communications and
serving as nodes in a network. These
systems generally include three basic
types of products: front-end processors, intelligent switches, and remote
concentrators.
In the late 1970s, IBM's SNA and
the ISO's OSI model advanced data
communications as a function separate from applications processing.
SNA and OSI defined a network as a
physical entity separate from its participating hosts and terminals. The
implementation of a physically separate communications function occurred through a system of small
dedicated computers. Users placed

these communications processors at
the front end of a mainframe, or allowed them to function independently as concentrators and switches
within their architectures.
In most communications processors,
under the direction of the CPU,
some components perform functions
for the whole communications processor, while others perform functions for specific groups of lines.
Among the former are host interfaces, input/output (110) processors,
reference clock, and operator interface. Among the latter are the processor's line bases and line sets.
There are two kinds of network architectures: those for communications among computers and
terminals from a specific vendor,
and those for open communications
regardless of the vendor of the communicating devices.
This report discusses communications processor design, evolution,
and position in modern network architectures. It concludes with Selection Guidelines for users.

Network Architectures

Technology Basics
The definition of a communications processor varies greatly. Network designers hold one view of
what a communications processor does, but equipment manufacturers hold another. The term "communications processor" has covered equipment
ranging from an IBM 3745 to a four-port packet
assembler/disassembler (PAD).
A network designer believes that a communications processor should set up connections to
transmit and receive data, multiplex and demultiplex data, frame and unframe messages, perform
error correction and protocol conversion, choose
transmission routes, and collect performance and
traffic statistics. Unfortunately, this definition has
led many manufacturers to classify their protocol
con verters, PADs, terminal controllers, and statistical multiplexers as communications processors.
Manufacturers consider communications processors as devices that connect terminals to networks
and maintain control through changing network
conditions. This concept clouds the definition of
the equipment: an IBM 3745 and a protocol converter do not belong in the same category.
Datapro defines a communications processor
as a multifunctional, intelligent device dedicated to
communications and serving as a control point, or
node, in a data communications network. It functions as a front end to a mainframe, as an intelligent switch, or as a remote concentrator. As a
front-end processor (FEP), the communications
processor acts as a peripheral device locally attached to one or more large computers, relieving
them of the overhead involved in message handling and network control. An intelligent switch
routes messages among the network's various end
points and participates in the network's control
and management, either under the control of a
master (usually front-end) processor or as a peer of
other intelligent switches. A concentrator controls a
community of terminals, clusters of terminals, or

Open Systems Interconnection (OSI) provides a

kinds of network architectures.

(

Mainframe Architectures
In network architectures designed by mainframe
vendors, the communications processor functions
most often as a front end and controls communications in conjunction with one or more software
systems in the host computer. In general, the frontend processor handles the Data Link through Session layers of the ISO model, with host software
implementing the Presentation and Application
layers. The activity in the layers varies, depending
on the architecture. In Unisys' DCA, the DCPSeries front end controls many Presentation layer
functions, while in IBM's SNA, the host's access

Delran NJ 08075 USA

method (along with software residing in the terminal controllers) handles communications down to
the Session layer, with the 37XX front end acting
almost as a channel-attached packet switch. The
range of control assigned to front-end processors in
other mainframe architectures varies between
those extremes.
In all mainframe architectures, the same communications processor models that serve as front
ends also function as intelligent switches and as
remote concentrators. In these functions, the communications processors usually appear in smaller
configurations than they do as front-ends. Communications processors working in mainframe architectures also perform intelligent gateway functions.
In this application, the communications processor
provides the interface between the mainframe network and communications facilities outside the

MAY 1990

Processors

architecture, particularly public, packet-switched
data networks using X.25 protocols.
Open Architectures

In an open architecture, such as X.25, the communications processor serves as an intelligent packet
switch, implementing the Data Link through
Transport layers via a uniform set of complementary protocols. Designed specifically for public
data networks, X.25 protocols establish virtual circuits, or logical paths through the network, for devices from any vendor. Communicating devices at
either end of the virtual circuit must handle the
Session, Presentation, and Application layers according to their own protocols.
In a public network, the network provider is
responsible for network management. The X.25
communications processors in such a network,
therefore, carry a heavy load of access, error, and
class-of-service control, along with provisions for
statistically recording traffic and usage data for
individual users.
Communications processors operating in fullscale X.25 configurations seldom perform gateway
functions. The user must comply with the network's protocols, either through X.25 software residing in a participating host or its front-end
processor, or through a packet assemblerl
disassembler (PAD) that handles the Physical and
Data Link layers of the architecture. Table 2 shows
the protocols supported by various vendors' communications processors.
Vendors offer transparent architectures as
low-cost alternatives to mainframe architectures
and X.25 implementations. These architectures are
usually stripped-down versions of X.25 without the
network administration and class-of-service overhead necessary to operate a public or large private
network. In these architectures, the communications processor functions primarily as a switching
concentrator, providing services at the Data Link,
Network, and Transport layers. Most of these concentrators evolved at the high ends oflines of statistical multiplexers, adding the crucial routing and
flow control features that qualify them as communications processors. Some of these products offer
integrated network management functions, such as
error logging and performance statistics, but most
rely on separate, complementary network management systems for these functions.

Evolution of the Communications Processor

Two developments in the late 1960s provided the
technical base for the modern communications
processor: the minicomputer and ARPAnet. The
minicomputer performed a number of functions
more efficiently than a mainframe and supplied
the bus architecture that gave communications
processors modularity and flexibility. ARPAnet,
the first large-scale packet switched data network,
produced the fundamental design principles for
current data communications architectures. From
these principles originated the intelligent virtual
circuit switch, the first functional communications
processor.
A later development in minicomputer applications created the distributed processor, a small
computer dedicated to part of a larger application
that performed communications with its peers in a
distributed network. Distributed processing contributed the idea of intelligent communicationshandling under software control.
The lower cost of dedicated processing in
small computers made feasible the idea of dedicating a small computer to off-load intelligent
communications-handling from the mainframe.
The first intelligent front ends, such as IBM's 3704,
predate modern network architectures and, to a
large extent, made such architectures possible.
The microprocessor also contributed to the
development of the communications processor.
The advent of inexpensive silicon intelligence enabled designers to implement the hierarchical
scheme of the typical communications architecture
in hardware, with dedicated microprocessors performing low-level functions and reporting to larger,
more complex processors at higher levels. Indeed,
some line bases in present-day communications
processors are programmable, receiving downloads
from the units' CPUs that describe protocol and
synchronization. Some systems comprise entirely
redundant, microprocessor-controlled modules
that perform the functions of other modules, using
the proper software load.

The diagram shows the hierarchical, bus-based architecture ofa typical communications processor. Such a processor can contain more than one host interface, several I/O processors, and many line bases. Each line base
serves communications lines ofa specific synchronization, speed, and protocol. Each line set serves lines with a
specific, physical interface. The modular arrangement of line bases and line sets on the processor bus allows
easy configuration and reconfiguration.

data buffering and queuing; multiplexing; message
framing and unframing; control transmission errors; message sequencing; protocol conversion;
message pacing and flow control; message or
packet assembly and disassembly; route selection;
session establishment and disconnection; and data
formatting.
Intelligent switching is slightly less complex.
When acting as a dedicated switch, the communications processor does not carryon a running dialog with a host computer and is not responsible for
end-to-end establishment and disconnection of sessions. Still, an intelligent switch in normal operation must perform several basic functions.
Since concentration is the simplest task performed by a communications processor, it can be
confused with less sophisticated, single-function
devices like statistical multiplexers, protocol converters, PADs, and terminal cluster controllers.
Indeed, the widespread use of microprocessors and
the declining cost of silicon intelligence, has enabled many devices at the high ends of these lines
1990 McGraw-Hili, Incorporated. Reproduction Prohibited. Dalapro Research.
Delran NJ 08075 USA

to approach the functions of true communications
processors. In true communications processing,
like concentration, however, a dynamic process
occurs that involves feedback from other intelligent devices in the network. Statistical multiplexing, protocol conversion, and packet assembly/
disassembly are basically static processes that do
not change as conditions change in the network.
An intelligent concentrator participates in the
control of the network, either under the direction
of a master processor or as a peer of other concentrators and switches, receiving status information
from the network and changing its behavior accordingly. These changes include accelerating or
withholding transmissions, initiating diagnostic
procedures for pathways and devices in its local
domain, and controlling access to the network
from its locally attached devices. Some sophisticated terminal controllers, notably IBM's 317 4s,
perform some or all of these functions.

MAY 1990

C13-010-206
Processors

Design

The basic design of almost all communications
processors follows a three-tiered, hierarchical
plan-a plan that they share in common with digital PBXs and with a number of other data communications components.
The device's central processing unit (CPU)
with its main memory sits at the top of the hierarchy. The CPU controls the communications processor's operation according to the rules and
parameters of its operating software and, in frontend configurations, in conjunction with instructions from the host computer. In general, the CPU
performs addressing, route selection, protocol conversion, access control, session establishment,
application-level formatting, and error logging. It
also delegates rote operations to subsidiary components.

Front-End Processors (FEPs): Communications
processors configured as front ends must have at
least one host interface, which handles communications between the front-end processor and the
host's byte or block multiplexer, or selector channel. The host interface buffers data from the front
end's CPU, assembles it into parallel bit streams of
a format specific to the attached host channel, and
transmits it up the channel to the host. For data
from the host, it performs the same process in reverse. The host interface converts data from the
communications processor's internal word size to
that of the host computer.
Input/Output Processors: Some communications
processors contain one or more input/output processors that transfer data between the CPU and
attached storage peripherals. In some cases, the I/O
processors arbitrate among the various line bases
for access to main memory and to the CPU, handling interrupts generated by the line bases or host
interfaces to gain the attention of the CPU, or controlling the line bases' and host interfaces' access to
main memory. In communications processors with
more than one I/O processor, each 110 processor
usually controls a set complement of storage units
or communications lines.
Reference Clock: The reference clock generates a
timing signal for other components of the communications processor. In many systems, the CPU

MAY 1990

Communications
Processors: Technology
Overview

Datapro Reports on
Data Communications

performs reference timing. Some systems have separate reference clocks for timing signals at different
data rates.

Operator Interface: The operator interface allows
an operator to monitor and control the communications processor and to run diagnostic tests. In
newer and more sophisticated systems, the operator interface works under software control from a
dedicated console, which usually contains a display
unit and a printer for logging. In older communications processors, the operator interface works
through a front panel equipped with manual
switches and indicator lights.
Line Bases and Line Sets: AU of the aforementioned devices perform functions that are shared
among all communications lines; they sit just below the CPU in the communications processor's
internal hierarchy. On the network side, the "business end" of a communications processor, the line
bases and line sets complete the hierarchy.
A line base, sometimes called an attachment
base, interface base, or interface module, handles
communications at the Data Link layer between
the communications processor and a group of attached communications lines that share a common
synchronization pattern, line speed, and (sometimes) protocol. Each line base usually contains a
dedicated microprocessor that performs framing
and stripping, message buffering, message sequencing, synchronization, and error detection under the
direction of the CPU. Most current communications processors accommodate from 8 to 32 line
bases, each of which handles from 2 to 8 line sets.
A line set handles communications at the
Physical layer between its attached line base and
from one to eight communications lines. All the
communications lines attached to a line set must
use the same physical interface at approximately
the same data rate. The line set handles serialization of data and interface-level control signaling.
Parallel Data Bus: All components of the communications processor communicate with one another
over a parallel data bus, usually located along the
backplane or a side plane of the processor's cabinet. The physical bus architecture, popularized by
minicomputer design, supports easy installation

and replacement of parts. In a hierarchical architecture, the bus also accommodates easy reconfiguration. To replace asynchronous communications
over voice grade lines with HDLC communications over wideband or satellite circuits for a 16line segment of a network, a user might need only
to replace one line base and eight line sets, rather
than swapping out an entire front-end processor.
The hierarchical design extends the communications processor's functionality over time and helps
to protect the user's investment. Figure 2 shows the
hierarchical configuration of a generalized communications processor.

Selection Guidelines
The principal advantage of a communications processor as a networking tool is the physical and logical separation of the networking function from the
applications of its end users. Whatever its architecture, such a network functions for any application;
grows in size without qualitative change to accommodate new applications; and runs new applications through the installation of relatively
standard, intelligent components. The user need
not redesign and rebuild a modular network to
change the network's ultimate purpose.
Programmable, software-controlled communications processors are especially useful tools in
standalone networks because they accommodate
not only changes in application but also the effects
of technical progress. A software-controlled communications processor with a good design can survive breakthroughs in networking techniques
through relatively simple upgrades. The

Delran NJ 08075 USA

C13-010-207
Processors

microprocessor-controlled line bases, and even line
sets, provide an even more flexible buffer against
obsolescence.
In operation, a network controlled by communications processors survives the total failure of
one or more of its host processors. In a multi host
network, front-end processors switch users from
applications in a failed host to similar or identical
applications in a backup host, perhaps elsewhere
on the network. In a single-host network, a functioning front end allows service to degrade gracefully in the event of a host failure, sometimes
allowing users to terminate their tasks before total
system failure, or allowing communications among
distributed application processors in the absence of
the controlling host.
The communications processor still fulfills its
original purpose: relieving the host of the overhead
generated by keeping track of a network. Today's
networks are orders of magnitude more complex
than those of the mid-1970s when the first communications processors appeared. Thanks to the declining costs of memory and processing power,
many oftoday's communications processors are
faster and more powerful than mainframes of that
era.
The complexity of communications processors, however, poses problems. In an era of userfriendly hardware and software, the
communications processor remains a device hospitable only to trained engineers. Most require programs written in an arcane, Assembler-level
language, sometimes (but not always) with the benefit of pregenerated macros in the host access
method .•

Communications Capabilities of
Minicomputers and Small Business Computers
The minicomputer market has increased in size by 20
percent per year for the past five years and will continue at
that pace for the next few. This growth has occurred
despite the now ubiquitous presence of the microcomputer. In order for minicomputers to continue to earn their
keep in favor of lower priced microcomputers, they must
be able to support multiple terminals and applications,
and, generally, be more versatile. One application which
has taken on greater significance for minicomputers and
small business systems is communications. Minicomputers are now being used with increased frequency as
gateways for the subordinate terminals they service.
Virtually every currently marketed small computer system
is now equipped with some sort of data communications
capability, ranging from simple dumb terminal emulation
to sophisticated communication software and hardware
packages that permit it to serve effectively as a complete
communications processing product. Interfacing with
mainframe equipment and/ or other small computers
permits these systems to perform an endless variety of
communication processing functions, including front-end
processing, remote concentration, message switching,
network processing, and terminal control. The small
computer system's internal processing and storage
capabilities enable it to do some data processing locally as
well as handling code translation, editing and control
functions in connection with the data communications
activities. Whether utilized as a dedicated communications
processor or as an applications processor that performs
some communications functions, a small business computer can be used to form a basic building block of a
data communications network.
In general, the level of sophistication of the data
communications capabilities of a particular system can be
assessed by the variety and number of communications
features-both hardware and software-it supports.
Naturally, not every small system is supported for all types
of functions to the same extent.

(

Support may be provided only for basic batch terminal
communications. Remote job entry products and
procedures established in the 1960's by IBM, Burroughs,
Control Data, Honeywell, and Univac have become de
facto standards for batch data communications and it is
not uncommon on small computer systems for a vendor to
provide a variety of interchangeable software packages
with which the user can emulate IBM's 2780 or 3780 Data
Communications Terminal or its 360/20 HASP
Multileaving workstation, Burroughs' TC Series
terminals, Control Data's 200 User Terminal, Honeywell's
GERTS, or Univac's 1004 or OCT 2000.
More extensive communications capabilities are
represented by those systems that can support multiple
workstations, enabling the system's processor to function
as an intelligent clustered terminal controller. Some

report includes 71 vendors representing 244
minicomputer systems. All systems featured have
been judged by Datapro to offer substantial
communications support.

systems provide emulation packages for popular
interactive mainframer-produced terminals, such as the
IBM 3270 Information Display System, while others leave
the management of the interaction between the
workstations and a remote host to be programmed by the
user.
Systems that can handle multiple communication lines,
support a variety of communications protocols, and serve
in any of several communications capacities are available
from a number of minicomputer and small business
computer vendors. For example, Data General's Nova
and Eclipse minicomputers have been continuously
enhanced with communications hardware and software to
provide for a wide range of communications applications,
and can be configured as channel-attached front-end
processors, remote communications concentrators, or
distributed processing systems. And Digital Equipment's
PDP-II family supports virtually all modes and types of
data communications protocols, and facilities, and.
provides over twenty different line controller and interface
sets to handle local, remote and interprocessor
communications.
When not available directly through the manufacturer,
communications features are often added by OEMs,
distributors, and similar third party organizations. And, of
course, because the equipment is essentially a computer,
the user can program whatever special requirements are
not supported by the vendor.

The Comparison Charts
The comparison chart data presented in this report was
gathered as a part of Datapro's preparation of the 1982
versions of "All About Minicomputers" and "All About
Small Business Computers," and "All About Superminis,"
which appear in OAT APRO 70, and "Minicomputer
Specifications," "Small Business Computer Specifications," and "Supermini Specifications" which appear in
DATAPRO REPORTS ON MINICOMPUTERS. As
the title of the present report suggests, the broad-based
information presented in the "All About. ... " reports has
been condensed and edited, to enable us to zero in on those
products which provide significant data communications
features and to concentrate on just those capabilities. All
models selected for inclusion in this report were judged to 1>

1:> have substantial communications capabilities using
several criteria. For example, systems to which at least 16
communications lines can be attached or that provide
interprocessor communications functions under major
network architectures have been included.
The resulting comparison charts can be effectively used to
conduct a first-level search of minicomputers and small
business computers that meet your communications
requirements. For example, if you are looking for a system
that can support high speed data transmission to a remote
host, quickly scan the charts and jot down those
vendors/ models which provide the range of speeds you
require. Or, if you know that your applications require a
certain minimum main memory capacity for off-line
processing, and you are looking for a system that can also
provide support for interactive IBM 3270-type data
communications, a complete list of those systems that
satisfy both requirements can easily be made.
Once your search has narrowed down the manufacturers
and model numbers of equipment that satisfies your needs,
you may wish to know full details about the computers
you've selected. If so, simply turn to the Index of this
service and locate each system's detailed report, which
contains complete information on the communications
capabilities of the system, including our analysis of how it
fits into the data processing environment from a data
communications point of view and pricing details of all
communications hardware and software features offered.
Whenever you seek more information on a system that is
not covered in an in-depth report in DAT APRO

contact us directly via the Inquiry Service and get the facts
you need by telephone or mail. (This service is fully
described behind the Inquiry Service index tab.)
Comparison Chart Entries

The accompanying comparison charts summarize the key
characteristics of the data communications functions of
244 commercially available minicomputers and small
business computers from 71 vendors. The information
presented in the charts was supplied by the manufacturers
and suppliers from November 1981 to February 1982. The
cooperation of the vendors who provided this information
to the Datapro staff for these reports is gratefully
acknowledged.
Main Storage

Our comparison charts show the maximum capacity of
main memory available for each computer expressed in
bytes.
The amount of internal storage is one of the most
significant characteristics in appraising the power of any
computer. The amount of productive processing that a
computer can perform during anyone run is largely
determined by the number of instructions and/ or
operands it can hold. It is important to choose the right
storage capacity; for nonmultiprogramming systems, that
usually means enough storage to hold your largest

program, operating system, and all associated subroutines
and data, but not too much more than that. It's also wise to
make sure that your computer's main storage capacity can
be expanded if necessary, preferably by simply plugging in
an additional storage module.
Number of Workstations Connectable

Another very important consideration for many users who
are considering the acquisition of a minicomputer or small
business computer for use in a communications processing
environment is the number of workstations it can support.
Workstations, in this case, can mean most any type of
device, whether remotely or locally connected, that can
input and / or receive data from the minicomputer or small
business computer. When the system is used in a business
environment, for instance, the workstation would
normally be a data processing device or terminal, but in a
manufacturing or distribution environment the workstation could be a sensor or transmission unit that simply
transmits signals back to the system for processing.
Communications Capabilities

Synchronous and asynchronous have entries of standard,
optional, or no, indicating their availability, and also a

Purchase price of memory module stipulates the costs of
various sizes (when available) of memory increments, with
the actual sizes in parentheses.
Monthly maintenance price of basic system shows the
maintenance costs of the basic system as described above.
If you'll need two or more systems, it's worth noting that
some of the manufacturers offer sizeable discounts from
their list prices on orders for mUltiple computers.
Discounts of up to 40 percent are not unusual on large
orders. Discounts available indicates the types of discounts
offered by the vendor for each model. This entry will vary
by model for many manufacturers with mUltiple lines of
systems.

Date of first U.s. delivery tells when the first production
models of each system were delivered (or are scheduled to

Number installed to date shows how many systems of each
type had been delivered to customers as of approximately
February, 1982. Nearly all of the figures were supplied by
the manufacturers themselves, and a number of companies
chose not to release this information.

Communications Capabilities of
Minicomputers and Small Business Computers

t> communications

lines can be attached or that provide
interprocessor communications functions under major
network architectures have been included.

The resulting comparison charts can be effectively used to
conduct a first-level search of minicomputers and small
business computers that meet your communications
requirements. For example, if you are looking for a system
that can support high speed data transmission to a remote
host, quickly scan the charts and jot down those
vendors/ models which provide the range of speeds you
require. Or, if you know that your applications require a
certain minimum main memory capacity for off-line
processing, and you are looking for a system that can also
provide support for interactive IBM 3270-type data
communications, a complete list of those systems that
satisfy both requirements can easily be made.
Once your search has narrowed down the manufacturers
and model numbers of equipment that satisfies your needs,
you may wish to know full details about the computers
you've selected. If so, simply turn to the Index of this
service and locate each system's detailed report, which
contains complete information on the communications
capabilities of the system, including our analysis of how it
fits into the data processing environment from a data
communications point of view and pricing details of all
communications hardware and software features offered.
Whenever you seek more information on a system that is
not covered in an in-depth report in DAT APRO
REPORTS ON DATA COMMUNICATIONS, please
contact us directly via the Inquiry Service and get the facts
you need by telephone or mail. (This service is fully
described behind the Inquiry Service index tab.)
Comparison Chart Entries

The accompanying comparison charts summarize the key
characteristics of the data communications functions of
185 commercially available minicomputers and small
business computers from 62 vendors. The information
presented in the charts was supplied by the manufacturers
and suppliers during December 1980 and January 1981.
The cooperation of the vendors who provided this
information to the Datapro staff for these reports is
gratefully acknowledged.
Main Storage

storage capacity; for nonmultiprogramming systems, that
usually means enough storage to hold your largest
program and all associated subroutines and data, but not
too much more than that. It's also wise to make sure that
your computer's main storage capacity can be expanded if
necessary, preferably by simply plugging in an additional
storage module.
Number of Workstations Connectable

Another very important consideration for many users who
are considering the acquisition of a minicomputer or small
business computer for use in a communications processing
environment is the number of workstations it can support.
Workstations, in this case, can mean most any type of
device, whether remotely or locally connected, that can
input and/ or receive data from the minicomputer or small
business computer. When the system is used in a business
environment, for instance, the workstation would
normally be a data processing device or terminal, but in a
manufacturing or distribution environment the workstation could be a sensor or transmission unit that simply
transmits signals back to the system for processing.
Communications Capabilities

Maximum no. of lines indicates how many communications lines can be physically connected to a particular
system. The types of lines are specified in the next two
entries. The entries in these three categories represent the
raw outer limits of line number, type, and speed provided
by each system.
To utilize this information properly. the reader must take
into consideration two important factors. First, the line
mix (the number of lines of each type and speed) and the
resource mix (the number and type of workstations,
peripherals, and other facilities) determine the actual
practical limits of the system. For example, the number of
high speed communications lines that are physically
attachable to a processor is generally much less than the
number of low or medium speed lines. Secondly, the
throughput capabilities of the system vary radically,
depending not only on the physical configuration of the
hardware but also on the system's software requirements.
Even if the system is configured within recommended .
physical bounds, a heavy processing load can reduce
throughput to below an acceptable level.
Synchronous and asynchronous have entries of standard,
optional, or no, indicating their availability, and also a
notation as to the speed of each line in bits per second
(bps). Most entries are of the type "to 4800 bps," indicating
one or more lines supporting transmission up to a
maximum of 4800 bps.
Protocols suppotted indicates the type of communication
protocols accommodated by hardware and software for
the model.
Network architecture supported indicates the communications network architecture support by this model. Entries t>

Pricing and Availability

1242.

Purchase price of basic system shows the minimUm
purchase price of the system. In the case of a system in
which each component is sold as a separate item, the
comparison chart shows the price of the CPU, power
supply, front panel, and minimum memory in the chassis.
In the case of a packaged system, the price includes all
standard components and facilities of the entry-level
model. For many of the systems listed, itemized pricing,
including all communications hardware and software
features, is provided in the system's detailed report, which
you can find using the Index of this service. If the system is
not covered in an in-depth report, detailed pricing can be
obtained through the Datapro Inquiry Service or directly
from the vendor.
Purchase price of memory module stipulates the costs of
various sizes (when available) of memory increments, with
the actual sizes in parentheses.

Monthly maintenance price of basic system shows the
maintenance costs of the basic system as described above.
If you11 need two or more systems, it's worth noting that
some of the manufacturers offer sizeable discounts from
their list prices on orders for mUltiple computers.
Discounts of up to 40 percent are not unusual on large
orders. Discounts available indicates the types of discounts
offered by the vendor for each model. This entry will vary
by model for many manufacturers with multiple lines of
systems.

Communications Capabilities of
Minicomputers and Small Business Computers
Manufacturers of minicomputers and small business
computers constitute a prominent group of suppliers who
are actively pursuing the communications processor
market. Virtually every currently marketed small computer system is now equipped with some sort of data
communications capability, ranging from simple batch
terminal emulation to sophisticated communication
software and hardware packages that permit it to serve
effectively as a complete communications processing
product. Interfacing with mainframe equipment and / or
other small computers permits these systems to perform
an endless variety of communication processing functions,
including front-end processing, remote concentration,
message switching, network processing, and terminal
control. The small computer system's internal processing
and storage capabilities enable it to do some data processing locally as well as handling code translation, editing
and control functions in connection with the data communications activities. Whether utilized as a dedicated
communications processor or as an applications processor
that performs some communications functions, a minicomputer or small business computer can be used to form
a basic building block of a data communication network.
In general, the level of sophistication of the data communications capabilities of a particular system can be assessed
by the variety and number of communications featuresboth hardware and software-it supports. Naturally, not
every small system is supported for all types of functions
to the same extent.
Support may be provided only for basic batch terminal
communications. Remote job entry products and
procedures established in the 1960's by IBM, Burroughs,
Control Data, Honeywell, and Univac have become
de facto standards for batch data communications and it is
not uncommon on small computer systems for a vendor to
provide a variety of interchangeable software packages
with which the user can emulate IBM's 2780 or 3780 Data
Communications Terminal or its 360/20 HASP
Multileaving workstation, Burroughs' TC Series
terminals, Control Data's 200 User Terminal, Honeywell's
GERTS, or Univac's 1004 or OCT 2000.

(

More extensive communications capabilities are represented by those systems that can support multiple workstations, enabling the system's processor to function as an
intelligent clustered terminal controller. Some systems
provide emulation packages for popular interactive mainframer-produced terminals, such as the IBM 3270
Information Display System. while others leave the
management of the interaction between the workstations
and a remote host to be programmed by the user.
Systems that can handle multiple communication lines,
support a variety of communications protocols, and serve
in any of several communications capacities are available
from a number of minicomputer and small business
computer vendors. For example, Data General's Nova
JUNE 1980

A concise description of the communications
capabilities currently available on small computer
systems. Included are comparison charts featuring
167 models offered by 52 different manufacturers
that have been selected by Datapro as having
substantial communications processing capabilities.

and Eclipse minicomputers have been continuously
enhanced with communications hardware and software
to provide for a wide range of communications applications, and can be configured as channel-attached front-end
processors, remote communications concentrators, or
distributed processing systems. And Digital Equipment's
PDP-II family supports virtually all modes and types of
data communications protocols, and facilities, and provides
over twenty different line controller and interface sets to
handle local, remote and interprocessor communications.
When not available directly through the manufacturer,
communications features are often added by OEMs,
distributors, and similar third party organizations. And,
of course, because the equipment is essentially a computer,
the user can program whatever special requirements are
not supported by the vendor.

The Comparison Charts
The comparison chart data presented in this report was
gathered as a part of Datapro's preparation of the 1980
versions of "All About Minicomputers" and "All About
Small Business Computers", which appear in OAT APRO
70, and "Minicomputer Specificati<;ms", and "Small
Business Computer Specifications", which appear in
DATAPRO REPORTS ON MINICOMPUTERS. As
the title of the present report suggests, the broad-based
information presented in the "All About. ... " reports has
been condensed and edited, to enable us to zero in on those
products which provide significant data communications
features and to concentrate on just those capabilities. All
models selected for inclusion in this report were judged
to have substantial communications capabilities using
several criteria. For example, systems to which at least
16 communications lines can be attached or that provide
interprocessor communications functions under major
network architectures have been included.
The resulting comparison charts can be effectively used
to conduct a first-level search of minicomputers and small
business computers that meet your communications
requirements. For example, if you are looking for a system
that can support high speed data transmission to a remote
host, quickly scan the charts and jot down those vendors /
models which provide the range of speeds you require.
Or, if you know that your applications require a certain
minimum main memory capacity for off-line processing,
and you are looking for a system that can also provide
support for interactive IBM 3270-type data communica- I:>

requirements can easily be made.
Once your search has narrowed down the manufacturers
and model numbers of equipment that satisfies your
needs, you may wish to know full details about the
computers you've selected. If so, simply turn to the Index
of this service and locate each system's detailed report,
which contains complete information on the communications capabilities of the system, including our analysis of
how it fits )nto data processing environment from a data
communications point of view and pricing details of all
communications hardware and software features offered.
Whenever you seek more information on a system that
is not covered in an in-depth report in DAT APRO
REPORTS ON DATA COMMUNICATIONS, please
contact us directly via the Inquiry Service and get thefacts
you need by telephone or mail. (This service is fully
described behind the Inquiry Service index tab.)
Comparison Chart Entries

The accompanying comparison charts summarize the key
characteristics of the data communications functions of
167 commercially available minicomputers and small
business computers from 52 vendors. The information
presented in the charts was supplied by the manufacturers
and suppliers during November and December 1979. The
cooperation of the vendors who provided this information
to the Datapro staff for these reports is gratefully
acknowledged.
Main Storage

Our comparison charts show the amount of main storage
available for each computer in terms of the minimum
capacity and maximum capacity, expressed in words or
bytes.
The amount of internal storage is one of the most significant characteristics in appraising the power of any
computer. The amount of productive processing that a
computer can perform during anyone run is largely
determined by the number of instructions and/ or
operands it can hold. It is important to choose the right
storage capacity; for nonmultiprogramming systems, that
usually means enough storage to hold your largest
program and all associated subroutines and data, but not
too much more than that. It's also wise to make sure that
your computer's main storage capacity can be expanded
if necessary, preferably by simply plugging in an additional
storage module.
Number of Workstations Connectable

device, whether remotely or locally connected, that can
input and/ or receive data from the minicomputer or small
business computer. When the system is used in a business
environment, for instance, the workstation would normally be a data processing device or terminal, but in a
manufacturing or distribution environment the workstation could be a sensor or transmission unit that simply
transmits signals back to the system for processing.
Communications Capabilities

To utilize this information properly, the reader must take
into consideration two important factors. First, the line
mix (the number of lines of each type and speed) and the
resource mix (the number and type of workstations,
peripherals, and other facilities) determine the actual
practical limits of the system. For example, the number of
high speed communications lines that are physically
attachable to a processor is generally much less than the
number of low or medium speed lines. Secondly, the
throughput capabilities of the system vary radically,
depending not only on the physical configuration of the
hardware but also on the system's software requirements.
Even if the system is configured within recommended
physical bounds, a heavy processing load can reduce
throughput to below an acceptable level.
Synchronous and asynchronous have entries of standard,
optional, or no, indicating their availability, and also a
notation as to the speed of each line in bits per second
(bps). Most entries are of the type "to 4800 bps," indicating
one or more lines supporting transmission up to a maximum of 4800 bps.
Protocols supported indicates the type of communication
protocols accommodated by hardware and software Jor
the model.
Network architecture supported indicates the communications network architecture support by this model.
Entries may include, for example, Burroughs NDL,
DEC's DECnet, or IBM's SNA.
RJE terminals emulated indicates whether there is software available from the vendor for this system to enable it
to function as a "look-alike" for remote job entry
terminals. The terminals for which support is provided are
indicated.
IBM 3270 emulation is listed as a separate entry as a result
of an increasing amount of interest from our users concerning the emulation of the IBM 3270 Information
Display System.

Minicomputers -

Basic Characteristics

Many of today's mIniCOmputers are available with
communications interfaces and operating systems. When
equipped with appropriate peripherals, such as diskette
drives, and appropriate additional software, these systems
can perform communications related processing
functions, such as serving as distributed processing workstations, IBM 3270 or HASP emulation, and message
switching.

Dynamism and proliferation continue in the world of the
minicomputer. We hear daily of a continual stream of new
products entering the marketplace, with hardware and
software that take on many names. We hear of minicomputers, microcomputers, programmable controllers, microprogrammable data entry units, intelligent terminals,
accounting machines, large-scale programmable calculators, etc. We also regularly hear of old-line peripheral
device and terminal manufacturers announcing their entry
into the "minicomputer business" as they add programmable logic and memory to their formerly
unintelligent, hard-wired devices.

The net result of all these happenings is, more often than
not, confusion-at least when one tries to grasp the
meaning or direction of the industry in any overall sense.
The confusion may well be compounded when one sets
out to satisfy a known in-house need and wonders where
to begin looking for a specific minicomputer that will
satisfy that need at the best available price.

This report presents the salient characteristics of
251 minicomputers from 74 vendors. Prices and
capabilities of these machines span a wide range.
so prospective users should carefully check the
details of this report and the accompanying comparison charts.

This report on Minicomputer Characteristics can cut
through a lot of this confusion by providing a convenient
way to scan qUickly a comprehensive list of available
minicomputers, together with their primary speCifications
and prices.
The comparison charts that follow can be effectively used
to complete a comprehensive, first-level search of the
minicomputer universe in just a few minutes. For
example, if you want a minicomputer but know you can't
pay more than $5,000 for the basic CPU and memory,
then you can quickly scan across the charts noting the
entry "Price of CPU, power supply, front panel, and
minimum memory in chassis" and jotting down the name
and model number of each minicomputer that applies. Or,
your requirements may be for a minicomputer that has a
BASIC programming language in addition to removable
disk pack storage. A similar quick scan across the entries
called "Disk pack/cartridge drives" and "Compilers" will
produce a complete list of those minicomputers that
satisfy both requirements.
A significant aspect of any evaluation and procurement
cycle is to gather information about how well the product
has worked out for other customers. True, you are not
likely to find someone with exactly yoyr processing
requirements or company/information set-up, but there
will be similar elements.

THE COMPARISON CHARTS

Honeywell's powerfUl new Level 6 Model 47 minicomputer can
provide up to 2 million bytes of main memory and can process
COBOL programs seven times faster than the earlier Model 33.
The corifiguration shown includes (left to right) a 900-lpm printer,
VIP 7200 console display/keyboard, 500-cpm card reader, CPU
with 320K bytes ({{ memory, two diskette units above the processor,
two magnetic tape units, and two 256-megabyte disk units. Prices
for the Model 47 begin at $28,050.

The key functional characteristics of 251 commercially
available minicomputers from 74 manufacturers are presented in the accompanying comparison charts. Nearly
all of the information in the charts was supplied and I or
verified by the manufacturers during the months of
August and September 1978; their close cooperation with
the Datapro Research staff in the preparation of these
charts is greatly appreciated.
The chart entries and their significance to potential
minicomputer users are explained in the following
paragraphs, together with some useful guidelines for
selecting the most suitable minicomputer for your
application.

Minicomputers -Basic Characteristics

I:> Data Formats
Probably the single most important distinguishing
characteristic of a minicomputer is its word length, bits;
i.e., the number of bits (binary digits) that can be stored
in or retrieved from main storage during a single cycle. In
general, the longer the word length, the greater the
efficiency and accuracy of a computer's internal
operations-and the higher its price tag. Most of the
minicomputers currently on the market have a 16-bit
word length; this size neatly accommodates two 8-bit
bytes (characters) and has been shown to yield an
attractive balance between economy and performance for
many applications. Other widely used models have word
lengths of 8, 12, 18, 24, or 32 bits. The 8-bit
minicomputers are suitable for many functions where low
cost is more important than high precision or
sophisticated instruction repertoires-and they can be
particularly effective when extensive manipulation of
8-bit bytes must be performed. Entries also indicate parity
__ and error correction bits when applicable.

For most minicomputers; the fixed-point operand length,
bits is the same as the word length. Some machines,
however, have "extended precision" facilities which
enable them to handle arithmetic operands two or more
words in length. For many applications, extended
precision arithmetic is a valuable feature that helps to
overcome the limitations upon number range and
accuracy which are otherwise imposed by the short word
lengths used in most minicomputers. Some of the 8-bit
minicomputers are really byte-oriented machines, designed for efficient processing of variable-length operands
composed of one or more 8-bit bytes.

Instruction length, bits is one word in most computers,
but some are capable of using instructions which are two
or more words in length. In most two-word instruction
formats, the first word defines the operation to be
performed and the second word contains the address of
the required operand. The use of two-word instructions
greatly increases the number of storage locations that can
be directly addressed. This in turn simplifies programming-but the simplification is usually gained at the
expense of two words of storage space to hold each
instruction and two memory cycles for each instruction
retrieved for processing.

memory in their new products. It is clear that the demand
for higher performance at lower cost, togeth~r with continuing improvements in semiconductor technology, have
accelerated the trend toward the use of semiconductor
memories.
Two types of semiconductor memories appear in the
charts, MaS (metal oxide semiconductor) and bipolar
(bipolar tranSistor). MaS is decidedly more popular
because of its compactness and price. However, bipolar
technology, a type of transistor-transistor logic, offers a
classic trade-off-higher speed at the expense of more
space and greater power consumed, as well as greater cost.
The cycle time, microseconds/word for a storage device is
the minimum time interval that must elapse between the
starts of two successive accesses to anyone storage
location. Though cycle time ranks with word length as
one of the most significant individual indicators of a
computer's performance potential, it is definitely not safe
to assume that the computer with the fastest cycle time
will be the best overall performer in a particular
application. Other parameters that have an important
effect on a minicomputer's performance include the
flexibility and power of its instruction repertoire, the
number of storage cycles it requires to execute each
iflstruction, its input/output capabilities, etc.

Access time, microseconds/word is the actual elapsed time
between the CPU's request for data and the time when
that data is received (read). In core memory, the access
time is usually one-half the cycle time; semiconductor
memories do not display a similar relationship.
Our comparison charts show the amount of main storage
available for each computer in terms of the minimum
capacity and maximum capacity, expressed in words. In
the great majority of cases, storage is available in all the
usual binary increments of capacity. Thus, if a computer
has minimum and maximum storage capabilities of 4,096
and 32,768 words, respectively, it's safe to assume that
capacities of 8,192 and 16,384 words are also available.

It is important to choose the right storage capacity; for
nonmultiprogramming systems, that usually means
enough storage to hold your largest program and all
associated subroutines and data, but not too much more
than that. It's also wise to make sure that your computer's
main storage capacity can be expanded if necessary,
preferably by simply plugging in an additional storage
module.

Main Storage
The storage type generally falls into one of two basic
categories, magnetic core or semiconductor memory.
Magnetic core storage has been widely used for more than
a decade, and has proved to be fast, flexible, and reliable.
Semiconductor memories began to appear in commercially available minicomputers late in 1970, and most
minicomputer makers are now using semiconductor

Parity checking is a standard feature of some minicomputers and an extra-cost option for others. In still other
cases, the manufacturers maintain-with some justification-that the reliability of modern magnetic core and
semiconductor memories is so high that parity checking is
an unnecessary luxury unless absolute accuracy is a must.
Parity checking requires the addition of one more bit to
each main storage location. This added bit is set to the I>

1::> appropriate value (0 or 1) whenever a word is written into
main storage and checked each time the word is read out;
the technique permits detection of most, though not all,
read and write errors_
Error correction is a rather new feature which is beginning
to appear in some of the recent minicomputer offerings.

(

This feature involves appending five or six check bits to
each word of memory. The check bits, called a Hamming
code, and special algorithms allow a system to detect and
correct single-bit errors, and also to detect a fair proportion of the multiple-bit errors that occur.
Storage protection is a feature that prevents unauthorized
writing in certain areas of main storage. The protection
can be accomplished by hardware means, software means,
or a combination of both. Though unnecessary in simple
dedicated systems, an effective storage protection scheme
is an essential element in multiprogramming and
time-sharing environments.
Central Processor

Although there are many variations in their internal
architecture, the great majority of currently available
minicomputers are parallel, binary processors with
single-address instructions and fixed word lengths of 8,
12,16,18,24, or 32 bits.

(~-

Basic Characteristics

In single-address computers, the number of accumulators
can have a significant effect upon internal flexibility and
processing power. An accumulator is a register that holds
one operand and permits various arithmetic and logical
operations to be performed upon it (e.g., a second
operand might be added to the operand contained in the
accumulator, with the sum replacing the first operand in
the accumulator). In computers with multiple accumulators, instructions involving operands in two of the

accumulators can often be executed more rapidly than
instructions which require the retrieval of an operand
from main storage.
Indexing is an important form of address modification in
which the contents of a special register called an index
register are added to the machine address contained in an
instruction prior to its execution. An effective indexing
scheme is particularly desirable in minicomputers, since it
can help to compensate for their limited direct addressing
capabilities. The number of index registers serves as an
indication of a computer's programming flexibility and
efficiency. Prospective buyers should note, however, that
there are wide variations in the indexing schemes used in
current minicomputers. It is important to determine
whether the index registers are separate hardware registers
or simply reserved locations in main storage, whether
special instructions are provided for loading, incrementing, and testing the index registers, and how much
additional time (if any) indexing adds to the instruction
execution times. It should also be noted that many of the
current computers use "general registers" which can serve
as either accumulators or index registers.

The number of directly addressable words of main storage
is an important characteristic that may require some
explanation if you're investigating minicomputers for the
first time. The problem is that the short word lengths
impose serious limitations upon the number of bits that
can be assigned to hold the address part of each
instruction. A typical 16-bit minicomputer instruction
might consist of three parts: operation code, address
mode field, and the address itself. If 6 bits are assigned to
hold the operation code (permitting up to 64 distinct
operations) and 2 bits are used to designate the addressing
mode (permitting speCification of indexing and/or indirect
addressing), then only 8 bits are left to hold the address
field. Since these 8 bits permit direct addressing of only
256 distinct memory locations, it is clear that other means

Minicomputers -

t> will need to be employed to access most regions of the
computer's main storage. The most common solutions to
the problem are the use of multi-word instructions,
indexing, and/or indirect addressing.
Number of addressing modes refers to the number of
different types of additional addressing modes (other than
direct) available to the user. There are many addressing
modes being offered today: program-relative, base~
relative, indexed, base plus displacement, auto increment/
decrement, and many others. Many of these modes can
also be combined with indirect addressing, the most
popular of all non-direct addressing modes, to create an
almost unlimited list of addressing schemes.

Since indirect addressing is so prominent, it deserves a
short explanation. Indirect addressing is an address
modification technique in which the address part of an
instruction speCifies a storage location that contains
another address rather than the desired operand itself.
This second address may in tum be either the address of
the desired operand or another indirect address; the latter
case is called multi-level indirect addressing. Indirect
addressing permits the use of an entire word to hold an
operand address. It can also simplify programming and
speed up execution times in some applications by making
it possible to change the effective address of numerous
instructions by altering the indirect address in a single
storage location. Ea(;h level of indirect addressing,
however, usually requires one additional storage cycle of
execution time.
Control storage is an indication of the microprogrammability of the minicomputer. Microprogrammability is a
trait that enables the vendor and/or the user to tailor a
. minicomputer's internal processing capabilities to suit his
particular needs. In place of conventional hard-wired
logic, a microprogrammed computer uses sequences of
microinstructions, usually stored in a special read-only
memory (ROM), programmable read-only memory
(PROM), or bipolar read-only memory (BROM) unit, to
define the effects of each instruction in its repertoire. In
some cases the microprograms can be altered by the user
himself, while in others they are accessible only to the
vendor. Microprogrammability can greatly increase the
flexibility of a minicomputer, but its presence may
involve a trade-off in terms of reduced performance or
increased price. Entries here indicate both the type and
the size of central storage.

Although it is undeniably dangerous to make inferences
about a computer's overall performance capability on the
basis of instruction execution times, our charts show the
basic add time, microseconds to give a first-level
indication of fixed-point arithmetic speeds. In general, the
indicated add times are the times required to retrieve a
one-word operand from main storage and add it to
another operand already contained in an accumulator,
with no indexing or indirect addressing. Comparisons
based on add times can easily be misleading, however,
because of differences in word lengths and instruction
repertoires.

Basic Characteristics
Hardware multiply/divide facilities are standard in some
minicomputers and optional in others. When no hardware
facilities are present, multiplication and division must be
performed by means of programmed subroutines at a
significant reduction in execution speeds. Many minicomputer applications, however, impose little or no need for
multiplication or division operations, and in these cases
the hardware facilities would be superfluous.
Hardware /loating-point facilities are not included in the
standard instruction repertoires of most of the currently
available minicomputers, despite the fact that floatingpoint arithmetic is highly desirable, if not essential, in
many scientific applications. Where available, these
facilities can dramatically reduce the execution times for
certain programs by eliminating the need for timeconsuming floating-point subroutines.
Hardware byte manipulation is the ability to conveniently
process information expressed in the 8-bit character codes
which are rapidly becoming an industry standard.
Obviously, most of the 8-bit minicomputers are effective
byte manipulators, and many of the 16-bit machines offer
special instructions that permit either half of a word to be
addressed and processed as an 8-bit byte.
Battery backup is a feature unique to minicomputers with
semiconductor memory, which is volatile and requires
refreshing at regular intervals to retain the datil that has
been written into it. In the event of a power failure, the
contents of memory would be lost if the regulator power
supply were not backed up by the battery pack.
An interesting solution to this problem with semiconductor memories is furnished by Computer Talk, Inc., whose
battery backup feature causes the contents of memory to
be recorded on the system disk if a power failure occurs.
When power is restored, memory can be recreated by
copying from the disk.

A real-time clock or timer is another essential element in
most "time-conscious" systems. A real-time clock enables
the program to determine the time of day, while an
interval timer usually indicates the amount of time that
has elapsed since the occurrence of some significant event.
In many cases the timer can trigger an interrupt signal
when a predetermined -interval of time has elapsed.
Input/Output Control

A direct memory access channel (DMA) permits direct
transfer of I/O data between main storage and a peripheral
controller. When a DMA channel is used, the I/O data
bypasses the computer's main hardware registers, and the
I/O operation proceeds independently of program control
once it has been initiated by the program. In
minicomputers that lack a DMA channel, I/O data
transfers are generally carried out under direct program
control, with each word being transferred by way of the
processor's registers. Generally speaking, the DMA

and it causes far less interference with internal processing
operations. Regardless of the type of I/O control they
employ, most minicomputers can accommodate multiple
I/O devices and include appropriate facilities for
addressing the desired device.

Maximum I/O rate, words/sec is a measure of each
computer's potential ability to transfer data to and from
peripheral devices or other external sources. In machines
equipped with a DMA channel, the maximum I/O rate
frequently equals the cycling rate of the main storage
unit. These maximum I/O rates, however, can be quite
deceptive in the case of minicomputers. In general, their
storage capacities are limited, their capabilities for
simultaneous input/output operations are restricted, and
fairly complex programming is associated with I/O
operations. For all these reasons, I/O data rates
approaching the indicated maximum rates can usually be
handled only in short bursts, if at all.

An effective program interrupt facility is a requirement

for virtually all applications of a real-time nature. An
interrupt is a signal that causes a temporary suspension of
normal program execution so that the particular condition
that caused the interrupt can be dealt with. Interrupts fall
into two basic categories: internal and external. Internal
interrupts are usu?lly triggered by conditions such as a
memory parity error, an illegal instruction, or a power
failure. External interrupts usually indicate that a
particular peripheral device requires attention or has
completed an I/O operation. An interrupt usually results
in automatic storage of the current contents of the
instruction counter, followed by a transfer of control to a
software routine that determines the cause of the
interrupt and initiates the appropriate action.
The number of external interrupt levels provides a
reasonable indication of the power of a minicomputer's
interrupt system. It shows the number of different
external devices whose interrupt signals can be identified
by the processor-though it should be noted that this
identification process may require a fairly complex and
time-consuming sequence of instructions. Many of the
minicomputers offer additional external interrupt levels as
extra-cost options, and in these cases our charts show the
available range, from minimum to maximum.
Peripheral Equipment
The comparison charts summarize the standard peripheral
devices that are available for each minicomputer. (Full
details on the speCifications and prices of more than 900
peripheral and memory products can be found in the
Peripherals section of DATAPRO REPOR TS ON MIMCOMPUTERS. In addition, the individual minicomputer
system reports in the Computers section include coverage
of all the important peripheral devices offered with each
minicomputer.)
Users who are accustomed to larger general-purpose
computer systems will find that the term "standard
peripheral device" often has a somewhat different
DECEMBER 1978

Basic Characteristics
meaning when used by a minicomputer manufacturer.
Since comparatively few of the minicomputer makers
produce their own peripheral equipment, the indicated
availability of a given type of device may simply mean
that an appropriate interface is available to couple the
computer with a peripheral unit supplied by some other
manufacturer. In many instances the minicomputer
manufacturer buys the peripheral device from the
peripheral manufacturer and supplies an appropriate
interface for his minicomputer. Datapro has made every
effort to include only the peripheral devices that are
physically supplied by the minicomputer vendors;
therefore, prospective buyers should ask these questions
about each item of peripheral equipment they will need:
• Has it actually been installed and used with the
computer of interest?
• If so, what has the users' experience been'!
• What software support is available?
• Who will provide service for the device, and under what
conditions?
The inclusion of mass storage devices (magnetic disk
units) can greatly increase the data storage and processing
capabilities of a minicomputer system. Disk units enable
millions of characters of information to be constantly
accessible to the computer. Moreover, any desired record
can be retrieved, updated, and re-recorded on the disk,
usually within a fraction of a second.

By replacing or augmenting slower, less flexible file
storage media such as punched cards, paper tape, or
magnetic ledger cards, disk units can enable small
computers to handle applications and processing volumes
that would otherwise be impossible. The principal
disadvantages of disk units are their comparatively high
costs and the software complexities that are encountered
by users who attempt to harness their full potential. One
or both of these considerations will make disk units
impractical for many small computer buyers, despite the
obvious appeal of disk-oriented data processing.
The diskette, or "floppy disk," is an innovation that can
significantly reduce the cost of disk-oriented data
processing. The diskette itself consists of a flexible Mylar
disk, about 8 inches in diameter, that is permanently
housed in a plastic envelope. It can serve as an
input/output and/or random-access storage medium that
is conSiderably smaller in capability and slower in
performance than conventional disk units-but also far
lower in cost. Introduced by IBM in 1972, diskettes and
diskette drive units are now being produced by dozens of
vendors and are finding their way into numerous small
computer systems, such as the IBM System/32 and
I~urroughs B 80. Recent enhancements to the floppy disk
concept include more concentrated data storage and
"flippies" (floppy disks that utilize both sides of the
1>
diskette), allowing more data to be stored on-line.

Floppy disk (diskette) drives indicates whether floppies

Disk pack/cartridge drives signifies whether one or the
other, or both, types of devices can be interfaced to the
system and the minimum and maximum on-line capacities
available.
Drum/FIXed-head disk storage informs the reader as to the
availability of a drum or head-per-track (fixed-head) disk
drive and the minimum and maximum on-line capacities
offered.

Meta 4/5020 is $24.500.

1::> The other, more conventional types of mass storage
devices, cartridge and disk pack drives, provide access to
far more data and at significantly faster rates.
Unfortunately, they also carry price tags several times
higher than their floppy counterparts. Most of these 'units
employ cartridges or disk packs that can easily be
removed from the drive units and interchanged in much
the same manner as magnetic tape reels.
Some cartridge-type units either use nonremovable media
or use two cartridges, one fixed and the other removable.
Nonremovable disks impose two important limitations.
First, the system's file storage capacity is effectively
limited to the amount of information that can be stored
on-line. Second, disk dumps to create backup files for
efficient restart procedures in case of catastrophe are not
available to the user.
Interchangeable disks, conversely, provide great fleXibility
and make it practical to use small computers effectively
for both sequential and random data processing
applications. In sequential applications, files of virtually
unlimited size can be handled through the use of multiple
disk packs or cartridges.
Fixed-head (head-per-track) disk and drum units can
provide much faster access to on-line data than any other
type of mass storage device. The reason is that there is no
loss of time due to head positioning because a head is
provided for each track. The only delay is rotational delay
(latency), or the time required for the desired data to
move under the read/write head. But the price of this type
of equipment is higher than that of the preceding
varieties, and less data can be stored on-line. Fixed-head
devices are used when data bases are relatively small and
very rapid access to the information is required.

The indicated maximum storage capacities are shown in
thousands (K) or millions (M) of bytes and may be the
capacity of a single disk or the total capacity of two or
more (typically, four to eight) drives that can be
connected to one controller. It is difficult to imagine
minicomputer users wanting more disk storage, but if an
I/O slot is open, theoretically, another controller and its
associated drives can be added to most systems.
Magnetic tape cassettes and cartridges offer increased
convenience in that they can be transported and stored
with little fear of damaging the data that has been
recorded. What's more, price tags for cassette and
cartridge drives are significantly lower than those of the
more conventional reel-to-reel variety, but once again the
trade-off of slower transfer rates and reduced on-line
storage must be accepted. The charts indicate the
availability of magnetic tape cassettes/cartridges and
magnetic tape, %-inch drives and their associated transfer
rates in characters per second (cps) or thousands of bytes
per second (KBS).
Punched card input informs the reader if a punched card
reader is offered and its speed in cards per minute (cpm).
Serial (character-at-a-time) printers are enjoying increased
popularity with the prolific growth of the minicomputer
marketplace. The main reason is price; serial printers can
provide excellent-quality hard-copy reports for far less
money than the line-at-a-time printers used with larger
computers. However, for users who require faster printing
capabilities, line printers are also available for manY
systems. Serial printers generally range in speed' from
about 30 to 600 or more characters per second (cps),
while line printers operate at speeds of 100 to 2000 or
more lines per minute (Ipm). The user who needs faster
printed output can obviously get it, but he must be willing
to pay the higher price tag associated with the line
printers.

Software

A critically important area to be evaluated is softwarethe programming packages and languages used to program
the computer and thereby direct its operations. It is
important that you carefully investigate the available
software. This investigation should include the operating
systems, programming languages, preprogrammed utility
packages such as sorts and me maintenance, and
application packages such as payroll, inventory control,
general ledger, etc. Prospective buyers should carefully
note whether the software they will require is included in
the cost of the system or offered at extra cost.

Vendors' claims and promises concerning the availability
and capability of software should be carefully checked.
This is particularly true of software that has been
announced but not yet released. Vendors have frequently
failed to live up to their marketing pUblicity.
An assembler is a special-purpose program that uses the
computer's power to facilitate the preparation of other
programs. It enables the programmer to. write his own
program in a simplified format that uses mnemonic
operation codes and symbolic operand addresses. The
assembler program then converts these symbolic instructions into their machine-language equivalents, producing
computer programs ready for loading and execution.
Entries here indicate the availability of an assembler or, in
some cases, a macro assembler.

A macro assembler is another software tool to aid the
programmer and make his job a little easier. Macro
routines can be called by the programmer and copied right
into his program. This saves the programmer from having
to recode the routine each time it is used and also
eliminates the possibility of keying errors when that part
of the program is entered. As usual, there is a price to
pay: the use of macros usually wastes memory space.

Entries in this section of the charts indicate whether an
assembler, a macro assembler, or both are available.

programs. Compilers are now used in Virtually all large and
medium-scale computer installations because of their
demonstrated ability to slash programming costs-and
they are becoming increasingly available for minicomputers. This trend is possible because of the more
powerful central processors now being used, since
compilation is an intricate process that requires more
storage space and processing power than the earlier
minicomputers provided. Where compilers are offered,
however, they frequently limit the programmer to
restricted subsets of the standard programming languages
and/or require the use of a larger computer to perform the
compilation process.
Entries in this section of the charts may include COBOL
(COmmon Business Oriented Language), RPG (Report
Program Generator), FORTRAN (FORmula TRANslator),
BASIC (Beginners All-purpose Symbolic Instruction
Code), ALGOL (ALGOrithmic Language), or proprietary
languages that are available from a vendor for use on a
particular system, and indicate the availability of those
compilers for each minicomputer. The key word of
warning here is that if you use a language that is unique to
a vendor, you will be faced with a big problem if someday
you decide to change vendors. Your investment in
software will be lost, since the programs will not operate
on any other system.
An operating system facilitates the operation of a
computer by handling functions such as: (1) scheduling,
loading, and supervising the execution of programs; (2)
allocating storage and I/O devices; (3) initiating and
controlling I/O operations; (4) analyzing interrupt signals
and dealing with errors; (5) handling communications
between the system and its human operator; and (6)
controlling multiprogramming or time-sharing operations. 1:>

Minicomputers Typical entries describing the available operating systems
include "batch," which means that the system processes
one or more jobs sequentially and requires all data to be
supplied before initiation (communication between
operator and system is not permitted once the job has
begun); "interactive," which means that the system allows
data, parameters, etc., to be entered as the job is
executing; "real-time," which means that the system
responds to external demands on a priority basis; or
"time-sharing," which means that the system allows
multiple users to access the system and share all its
resources at the same time.

Language implemented in firmware and operating system
implemented in firmware tell the reader whether or not
the language processor and/or the operating system are
contained in microcode. The entries stipulate "Fully,"
"partially," or "no" to indicate the extent of firmware
implementation. An advantage to the user is that a
language and/or operating system implemented in
firmware frees up more memory space for the user's
programs and data. Also, the microcode is usually
inaccessible to the user (generally contained in read-only
memory), eliminating any possible tampering with the
language processor or operating system and reducing
chances for error. A third advantage derived from
firmware implementation is the ability to create more
sophisticated and complex system functions at the
hardware level. Microcode routines can be substituted for
often-used subroutines, thereby increasing system performance.
