MANAGEMENT

SUMMARY

In

June

1977,

Varian Data Machines

was

merged into

the Univac Division

of

Sperry-Rand and

is

now called

the Sperry Univac

Minicomputer

Operation. Varian

introduced the

V70

Series

in

1974

and

in

December

1976

released the

V77

series with increased memory and other

options.

Soon

after Sperry Univac's acquisition

of

Varian, software packages were announced making the

V77

line compatible with Univac hardware, and thereby

enrolled the

V77

line in Univac's Distributed Communi-

cations Architecture (DCA). In December

1978,

Univac's

Minicomputer

Operation

announced the V77-800, a

significantly improved model which extends the

V77

line

upwards. Since then, additional enhancements to both

. the

V77

hardware and software offerings, including new

disc drive, matrix printer, line printer, and magnetic tape

unit models and new system and applications software

modules, have been added. A new line adapter that sup-

ports multiple protocols (UDLC, SDLC, HDLC, and

ADCCP) has also been introduced.

The

V77

family can support slightly over one million

words (or over two megabytes)

of

main memory, depend-

ing on the model and system configuration. The systems

can perform as remote nodes and front-ends for each

other in a

V77

CONFIGURATION

The

V77

family

of

minicomputers includes four basic

models, each with a different processor, to provide four

levels

of price and performance.

The

V77-800

features a microcode processor

cycle

time

of

ISO

nanoseconds, and contains a lK-word, ISO-nanosecond

cache memory; this

is

more than twice the speed

of

the

V77-

600's cache memory. The

V77-800

is

reported to have double

the performance

of

the

V77-600,

which

is

the next fastest

V77

model.

1:> processors in either Univac, IBM, or packet-switching

networks. A complete software library supports these

applications,

as

well as time sharing,

HASP

/ RJE,

data

base management,

or

pure communications processing.

The intermediate-speed and high-speed

V77

models are

attractive from a communications standpoint because

they support shared memory. When a

V77

is

used as a

front-end to another

V77

host, shared memory between

them gives the host immediate access to data stored by

the front-end from communications lines. The extra step

of

moving data from the front-end to the host's memory

is

eliminated. Similarly, data released by the host for

front-end processing

is

available to the front-end without

first having to be transferred to the front-end memory.

Shared memory arrangements also permit establishment

of

a network where a secondary host

or

a secondary

front-end

is

able to access

data

awaiting prime processor

action when the prime processor fails; this

is

a definite

fallback advantage.

The ability to give special high-priority direct memory

access to disc files, at transfer rates up to 604K (16 bit)

words per second, should be

of

interest to networks that

require especially heavy access to random

files.

Binary Synchronous Communications protocol

is

sup-

ported

at

speeds up to 50,000 bps. Other control pro-

tocols are supported

at

speeds up to 9600 bps. Adapters

supporting the

UOLC

and

SOLC

bit-oriented protocols

are also available.

The utilization

of

different minicomputers for each

of

the

four models

of

the

V77

family

is

a departure from the

V70

product line where essentially one minicomputer served

almost all models.

The offering

of

predefined starting configurations sim-

plifies system building within

an·

architecture that

is

1:>

...

The

V77-600

features a 165-nanosecond, 64-bit word micro-

code processor which

was

essentially an improved version

of

the

V76

model

of

the

V70

minicomputer series. The

600

can execute a macroinstruction

in

two or three microcycles.

Cache memory

is

available

as

an option with the

600.

The intermediate-speed

V77-400

has a 220-nanosecond, 32-

bit word microcode processor. The processor executes a

macroinstruction in three

or

four microcycles.

The slowest-speed

V77-200

has a 165-nanosecond, 24-bit

word microcode processor. This processor requires two to

three microcycles

to

execute a macroinstruction.

The

V77-800

has an average main memory

cycle

time

of

600

nanoseconds. Main memory for the other three models

features the same

660

nanosecond

cycle

time.

All

processors

have a 16-bit word organization.

In addition to the processor differences, the models differ

in

their: maximum allowable memory

size;

internal data

transfer methods; firmware options; number

of

memory

ports; and supportability

of

cache memory, memory parity,

memory protect, and floating-point options.

Multi-line communications controllers are available

to

handle synchronous and asynchronous

lines

in either full-

or half-duplex modes with speeds up to

9600

bps. Binary

Synchronous Communications protocol

lines

are supported

up to

50,000

bps. Standard interfaces include RS-232-C,

CCITT

V.24,

20

ma and

60

ma current loop and telegraph

network-compatible.

Vortex Telecommunications Access Method (VT AM)

modules drive the communications controllers, handle the

communications lines for supported protocols, and provide

for network control and modification.

Along with the announcement

of

the

V77-S00

in

December

1978

came the release

of

a

new

operating system, Summit,

which

can run on either the

600

or

800

models and includes

all Vortex

II

features. Additionally, Summit can operate

with a number

of

separately-priced software features in-

cluding compilers for Fortran

77

and Pascal compilers and

QL/77, an inquiry language that works with the TOTAL

data base management system. Not all

of

these features can

be used on the

600,

because

of

its limited memory. Summit

USER

REACTION

It

is

against Sperry-Univac policy to provide user names;

however, three

V77

users did respond to the Computer

Systems survey Datapro conducted

in

early

1980.

All were

using V77-600 models, which had been installed for

an

average

of

15

months. Two

of

the users each had one

V77-600, and the third had 6 units. Applications for which

these systems were being used included accounting,

manufacturing, transportation, word processing, distri-

buted processing, transaction processing, and engineer-

ing/ scientific applications.

Because

of

the small number of respondents, it

is

in-

appropriate to calculate user ratings based on these

users' responses. Instead,

we

will

present a narrative

summary

of

their experiences, as follows:

These users had widely varying opinions

of

their

V77

systems. The most satisfied user, whose ratings were

consistently in the excellent-to-good range, felt

that

response time was good, that Univac had correctly

represented the V7Ts compatibility with the user's pre-

decessor system, that the productivity aids provided with

the system helped keep programming costs down, and

that delivery was on schedule and installation/ start-up

was smooth. The only negative comment by this user

was that the vendor had underestimated the disc require-

ments

of

the system.

The second user, whose ratings

fell

mostly

in

the good-

to-fair range, agreed that response time was good, and

that the productivity aids were helpful. He also noted

that

he

felt that the power

of

the system's mUltiprogram-

ming capabilities was a real asset. On the negative side,

he

felt that Univac's enhancements to the system (hard-

ware and software) were hard to keep up with.

The third user, whose ratings

fell

primarily in the fair-to-

poor range, reported that the system as proposed by

Univac was too small for his applications, that deliveries

of both hardware and software had been late, that costs

had exceeded the expected total, and that Univac did

not

live up to its promises in terms

of

software and

support. He specifically pointed out that he had had

"excessive problems with Eagle discs."

With as widely varying a group of opinions as these

users represent, it would be unwise to draw any firm

conclusions from their experiences. However, the specific

advantages and disadvantages they have found should

provide a starting point for future investigation.D

~

includes

an

interactive monitor for time-sharing, text editor,

PRONTO, and the communications access method.

A

V77

system

is

built around a mainframe chassis with

plug-in slots for additional memory modules, communica-

tions multiplexers, and

I/O

controllers. Generally, a

V77

system consists

of

a mainframe chassis with

24

slots. A

supplemental chassis can be configured within the main-

frame chassis for an additional

24

slots and, should more

be required, an expansion cabinet

is

available which pro-

vides

stilI

another

24

slots. The plug-in components are

detailed throughout this report along with the number

of

slots required.

V77-800

The

V77-800

represents the largest member

of

the

V77

family. Main memory ranges from

128K

to 2 megabytes

with an average

cycle

time

of

600

nanoseconds, some-

what faster than the other

V77

models. The performance

doubling compared to the

V77-600

is

achieved through the

faster memory (600- vs. 660-nanosecond cycle), faster

processor

(150-

vs.

16S-nanosecond cycle), and faster cache

memory (150-

vs.

370-nanosecond cycles); cache memory

is

a standard feature

on

the 800,· and optional on the 600.

Main memory for the

800

is

single-port, and can be shared

among up to four

800

systems via memory bus attachments.

The V77-800 also features as standard the Megamap

memory management system, which

is

available as

an

option on either the

400

or

600

systems. Megamap

is

not

available,

or

required, with the V77-200because main

memory is limited to

32K

words

(64K

bytes).

Both the

V77-800

and

600

can be configured to support up

to

256

communications lines. Both utilize the same

Data

Communications Multiplexers and line adapters, and can

support the same peripheral and

I/O

devices (including up

to

4800

megabytes

of

disc storage each).

Not

all

of

the software available on the

800

with the Summit

operating system

is

available on the

600.

For example, the

600

loaded with the Summit system cannot support the

Fortran

77

or

Fortran

IV

compiler.

V77-600

The foundation

of

the

V77-600

architecture

is

a dual-port

memory and up to three busses that permit variable,

or

even

customized, arrangements

of

data

transfer paths. Each

16K-, 32K-, 64K-word memory module has an

"A"

port

and a "B" port.

In a typical single processor arrangement, only the "A" port

is

used.

It

is

attached to the Memory Bus A and is the only

access to memory. The bus

is

also attached to a

370

nano-

second Cache Memory. In addition to being a funnel for all

transfers to and from memory, the Cache Memory, with

1024

words,

will

have the most recently used instructions

and data readily available for processor

use;

the information

is

accessible in little more than half the time required to

retrieve it from the

660

nanosecond main memory. The

Cache Memory is also attached to the Megamap and the

Option Board features. The latter feature, in

turn,

is

attached to one

of

the two processor lines. Data, instruc-

tions, and memory address commands traveling from the

processor to memory "functionally" go through the gauntlet

of:

processor to Option Board, Option Board to Megamap

for any address extension necessary, then to the Cache

Memory, to the Memory Bus A, and finally into memory

through Port A. Information traveling from memory to the

processor runs the same gauntlet in the other direction.

The largest memory addressable by the basic instruction

repertoire

is

32K words. When the memory size is greater

than 32K, the Megamap option

is

required. This memory

management feature divides physical memory into lK-byte

pages.

modate the above features. The 14-inch high version

is

identical to the 7-inch version, except that an additional 9

Each bus

that it does not support Cache Memory, Priority Memory

Access,

CONNECTION TO HOST COMPUTER

When a

V77

is

used as a front-end processor and another

V77

is

the host, the front-end can merely place data destined

for the host into memory shared

by

both the host and the

front-end. Conversely, data destined for a communications

line

is

placed by the host

in

the shared memory. Control

words resident in the shared memory and constantly moni-

tored by both processors serve as a means for inter-

processor communications. Alternatively, a conventional

V77-V77

Channel Interface can connect the front end and

host.

All

memory need not be shared. Each processor can have

one Memory Bus attached to the shared memory and an-

other Memory Bus attached to the non-shared memory.

Software modules are available which allow

V77

operation

within either Univac, IBM, or public packet-switching net-

works. One package, for example, allows Uniscope ter-

minals, and software, to operate with

V77

systems, and

permit V77's to communicate as distributed systems with

Univac hosts. Such communications emulates Univac

1004

remote batch protocol. Another package permits

V77

access

to an IBM 360/370 system in

3270

emulation, and yet an-

other permits.

V77

operation as a

HASP/RJE

workstation.

Another package provides X.25 compatibility permitting

V77

access to Canada's DATAPAC public packet-switching

network.

TRANSMISSION

SPECIFICATIONS

Multi-line controllers are offered for support

of

communi-

cations lines. Three Data Communications Multiplexers

(DCM) are offered to support

8,

32, or

64

lines. One

of

the

DCM's come in two versions; one version

is

for systems

with the Megamap feature, and the second

is

for systems

without Megamap. Nine types

of

Line Adapters are pro-

vided for attachment to the Data Communications Multi-

plexers. Depending upon the adapter selected, RS-232-C,

CCITT

V24,

20/60 ma current loop, or 20/60 ma relay

current loop interfaces are supported. One adapter provides

BSC protocol, one supports UDLC, SDLC, ADCCP, and

HDLC protocols and the others are for other character

control protocols. Where applicable, the required character

control protocol and line speed can be selected program-

matically.

All

Line Adapters, except the BSC and UDLC

Line Adapter, can support up to four lines operating at up

to

9600

bps. The BSC Line Adapter can support only one

line at up to

bps. The UDLC Line Adapter can sup-

port only one line

at

up to

9600

bps. Table

2,

Line Adapters

for the Data Communications Multiplexers, lists the line

interfaces offered.

Each

of

the

Data

Communications Multiplexers requires

two slots in either the mainframe chassis

or

the expansion

cabinet. Both the

V77-200

and

V77-400

are limited to a

single eight-line multiplexer, which

is

located in the main-

frame chassis for either system. The

V77-600

and

V77-800

can each support up to four 64-line multiplexers, yielding

up to

256

communication line interfaces. Whether the'multi-

plexers are housed in the main or expansion cabinet, or

both,

will

depend on the number

of

slots that are occupied

by

I/O

controller units. The maximum system configura-

tions for the

600

and

800

of

256

lines assumes that each

system

is

devoted almost entirely to communications

processing. The addition

of

I/O

controller units

will

pro-

portionately decrease the number

of

multiplexers (and lines)

that can be configured.

SOFTWARE

The

V77

operating system

is

VORTEX, a multi-program-

ming, disc-oriented system. For systems with a minimum of

16K and a maximum

of

32K

words

of

memory, VORTEX

I

is

the operating system. VORTEX II

is

used for systems

with more than 32K words

of

memory. The difference

is

that VORTEX II provides software support for the Mega-

map feature necessary to develop addresses greater than

32K.

The Summit operating system, announced

in

December

1978, is an expansion

of

VORTEX II.

It

is

designed to

operate on either the

V77-600

or

V77-800

system, although

each

will

also function with VORTEX II. Integrated within

Summit are the PRONTO transaction manager, a modifi-

cation

of

the

VORTEX

Telecommunications

Access

Method (VT AM), an interactive monitor for time-sharing

applications, and the capability to perform all the program

development

and

operating system functions

that

were

available with VORTEX II. Communications

is

enhanced

with

Summit

by

the addition

of

separately-priced modules

which

include a DCA package offering

V77

models the

capability

of

communicating with Univac

90

or

1100

Series

computers

in

a Distributed Communications Architecture

environment. A complete DCA package

is

available which

provides support for a mix

of

transaction and interactive

processing and remote job entry. Other options available

with Summit are the TOTAL data base manager, QL/77

(an inquiry language which works with TOTAL), and both

Pascal and Fortran

77

compilers.

Utilizing the Megamap memory, VORTEX

II

or

Summit

divides main memory into 512-word pages. Each user appli-

cation can utilize up to

64

pages

of

memory, or

32K

words.

This limitation

is

imposed by the maximum self-relative

address containable in the instruction format. The Mega-

map system keeps track

of

the actual memory locations

of

each user page. Importantly, the pages for a particular user

application need not be contiguous pages.

A set

of

modules that handle the telecommunications func-

tion are designated the Vortex Telecommunications Access

Method (VT AM). One module, the Communication Con-

trol Module,

is

required to drive the communications con-

trollers. A copy

of

the module

is

required for each type

of

communications controller attached to the system. For

instance, the Data Communications Multiplexors would

require a copy

of

this module to operate them. This module

performs the

I/O

handler function.

Another VTAM module

is

the Terminal Control Module.

This module performs the terminal handling function for

each type

of

terminal attached to a specific line (Line

Adapters).

The Network Control Module performs the logical link

function and provides the operator with an interface to the

communications system. Using a Network Definition Lan-

guage, the operator can instruct this module to alter the

network configuration. In this manner, lines or terminals

can be dropped

or

added, logical links can be rerouted, and

the status

of

a line can be ascertained.

Univac provides application packages that interface with

VT

AM. Included are:

•

HASP/RJE

-Permits a

V77

to serve as a remote work

station for

an

IBM 360/370.

• TEN04 -Emulates a Univac

1004

terminal.

• PRONTO -Provides interface control between com-

munications and

file

access function.

It

can multi-task

transactions and access

files

sequentially, index sequen-

tially,

or

via TOTAL. TOTAL

is

the VORTEX data base

management system. PRONTO permits a

V77

to operate

as a host to buffered asynchronous or IBM 3270-type

terminals. A

V77,

with PRONTO, can also operate as a

communications interface between an IBM 360/370 and _

multiple terminals. -

Programming languages offered include COBOL, FOR-

TRAN

77

and FORTRAN IV, RPG II, and DASMR (a

macro assembler),

MIDAS

is

the microassembler used

when the system includes

the

Writable Control Storage

option.

Several recently introduced packages include the VORTEX

Interactive Package (VIP),

the

Global Resource Access

Manager (GRAM), and the MANMAN Manufacturing

Management System. VIP provides multiple-terminal

V77-

600

and

-800

systems with the capability to edit source

files

on-line and submit background jobs, and includes a set

of

file

utilities; VIP can also be used as the base for QL/77

inquiry language programs and other optional software.

GRAM consists

of

several routines that provide terminal-

to-program, program-to-program, and distributed process-

ing module-to-program interfacing between a

V77

system

and

a

DCA

host. Both VIP and GRAM run under

PRONTO. MANMAN

is

an on-line interactive data base

management package for

V77-600

and

-800

systems that

provides a set

of

seven applications for manufacturing

environments: inventory control, purchasing work-in-

progress,

bill

of

material, material requirements planning,

capacity planning and scheduling, and cost accounting.

MEMORY

Within the

V77-600,

dual-port memory can

be

expanded

to

two million bytes

in

128K-byte increments.

Within the

V77-400,

dual-port memory can

be

expanded

to

SI2K bytes in 64K-byte increments.

Within the

V77-200,

16K, 32K, or

64K

bytes

of

single-port

memory

is

available.

The Memory Management System, Megamap,

is

required

on the V77400, 600, and 800

when

memory exceeds 32K

words. This feature, along with software support provided

in

VORTEX II, provides the addressing scheme that per-

mits attachment

of

over one million memory words, equiva-

lent to over two million bytes.

Cache Memory

is

available for the

V77-600

(370-nano-

second cycle time,

and

V77-800 (ISO-nanosecond cycle

time). Cache Memory

is

interjected between the processor

and main memory and can almost double the speed for

90

percent

of

the processor/main memory transfers. This

is

accomplished

by

continually loading the

1024

words

of

this

special memory with the most recently used instructions

and data

in

anticipation

of

use

by

the processor.

Available only on the V77400,

600,

and

800,

the Writeable

Store (WCS) option permits user incorporation into firm-

ware subroutines

of

instructions that are frequently used in

his

applications

or

that are time critical. When frequently

used instructions are microcoded, the overall overhead

of

the system

is

reduced. WCS

is

available for the V77400 and

600

in

a single 1024-word increment. Up to

12K

bytes

of

WCS

is

available for the

V77-800.

The

V77-800

can also

support

2K

bytes

of

PROM in conjunction with WCS.

PROCESSOR FEATURES

The Priority Interrupt Module feature permits assignment

of

processing priority to up to

64

interrupt-type devices

attached to the

I/O

Bus. Each device can

be

assigned one

of

eight priorities. The registers to store the mid-stream

processing

of

a lower priority

device

in

order to service

a higher-priority interrupt are included. Each module

occupies one slot

on

the Cardframe Chassis.

When direct memory access devices are attached to the

I/O

Bus, the Block Interlace Controller feature

is

required. This

feature

will

accommodate up to ten devices. A maximum

of

eight Block Interlace Controllers can

be

added to one

system and

will

handle a total

of

eight

devices.

Each con-

troller occupies one slot on the

chassis_

The Priority Memory

Access

feature provides for high-

speed data transfer between

discs

(or special interfaces) and

memory. This feature provides direct memory transfer

of

blocks

of

data over four channels. Each channel has a hard-

wired priority. Although two disc units can be physically

attached

to

a channel, only one unit can

be

active

at

a time.

The

PMA

feature requires the presence

of

Block

Tran&fer

Controller. A maximum

of

four such controllers are

allowed, with each controller occupying three slots

of

the

Cardframe Chassis.

MANAGEMENT

SUMMARY

In June

1977,

Varian Data Machines was merged into

the Univac Division

of

Sperry-Rand and

is

now called

the Sperry Univac Minicomputer Operation. Varian

introduced the

V70

Series

in

1974

and in December

1976

released the

V77

series with increased memory

and other options. Soon after Sperry Univac's acquisi-

tion of Varian. software packages were announced making

the

V77

line compatible with Univac hardware. and

thereby enrolled the

V77

line

in

Univac's Distributed

Communications Architecture (DCA). In December

1978,

Univac's Minicomputer Operation announced the

V77-

800, a significantly improved model which extends the

V77

line upwards.

It

is

scheduled for delivery

in

July

1979.

The

V77

family can support slightly over one million

words (or over two megabytes) of main memory, de-

pending on the model and system configuration. The

systems can perform as remote nodes and front-ends

for each other

in

a

V77

network, as independent proc-

essing systems,

or

as remote communications and dis-

tributed processors in either a Univac or IBM network.

A complete software library supports these applications,

CONFIGURATION

The

V77

family

of

minicomputers includes four basic

models, each with a different processor,

to

provide four

levels of price and performance.

The newly-announced

V77-800

features a microcode proc-

essor

cycle

time

of

ISO

nanoseconds, and contains a IK-

word, ISlklanosecond cache memory; this is more than

twice the speed

of

the V77-6oo's cache memory. The V77-800

is

reported

to

have double the performance

of

the V77-600,

which

is

the next fastest

V77

model.

t>

The intermediate-speed and high-speed

V77

models are

attractive from a communications standpoint because

they support shared memory. When a

V77

is

used

as a

front-end to another

V77

host, shared memory between

them

gives

the host immediate access to data stored

by

the front-end from communications lines. The extra

step of moving data from the front-end to the host's

memory

is

eliminated. Similarly, data released

by

the

host for front-end processing

is

available to the front-

end without first having to be transferred to the front-

end memory. Shared memory arrangements also permit

establishment

of

a network where a secondary host or

a secondary front end

is

able to access data awaiting

prime processor action when the prime processor

fails;

this

is

a definite fallback advantage.

The ability to

give

special high-priority direct memory

access to disc

files,

at transfer rates up to

604K

(16

bit)

words per second, should be of interest to networks that

require especially heavy access to random

files.

No feature

is

yet provided that supports a bit-oriented

line control protocol, but Univac

has

stated that adapters

supporting UDLC and SDLC

will

be

available

in

early

1979.

Binary Synchronous Communications protocol

is

supported at speeds up to

50,000

bps. Other control

protocols are supported at speeds up to

9600

bps.

The utilization

of

different minicomputers for each

of

the

four models of the

V77

family

is

a departure from the

V70

product line where essentially one minicomputer

served almost

all

models.

The offering of predefined starting configurations simpli-

fies

system building within an architecture that

is

already

devoid of complicated exceptions and conditions, making

it easy to tailor a configuration. 0

of

the

V76

model

of

the

V70

minicomputer series. The

600

can execute a macroinstruction in two

or

three micro-

cycles.

Cache memory is available

as

an option with the

600.

The intermediate-speed

V77-400

has a 220-nanosecond, 32-

bit word microcode processor. The processor

is

a new

Varian development for the

V77

family that executes a

macroinstruction in three

or

four microcycles.

The slowest-speed

V77-200

has a 165-nanosecond, 24-bit

word microcode processor. This processor requires two to

three microcycles

to

execute a macroinstruction.

The

V77-800

has an average main memory

cycle

time

of

600 nanoseconds. Main memory for the other three models

features the same

660

nanosecond' cycle time.

All

proc-

essors have a l6-bit word organization.

In addition

to

the processor differences, the models differ

in their: maximum allowable memory

size;

internal data

transfer methods; firmware options; number

of

memory

ports; and supportability

of

cache memory, memory parity,

memory protect, and floating-point options.

Multi-line communications controllers are available to

handle synchronous and asynchronous lines

in

either

fuIl-

or

half-duplex modes with speeds up to

9600

bps. Binary

Synchronous Communications protocol lines are supported

up

to

50,000 bps. Standard interfaces include RS232C,

CCITT

V24,

20

ma

and

60

ma current loop and telegraph

network-compatible.

Vortex Telecommunications Access Method (VT AM)

modules drive the communications controllers, handle the

communications lines

for

supported protocols, and provide

for network control and modification.

Along with the announcement

of

the

V17-800

in

December

1978

came the release

of

a

new

operating system, Summit,

which can run on either the

600

or

800

models and includes

all Vortex II features. Additionally, Summit can operate

with a number

of

separately-priced software features

including compilers for Fortran

77

and Pascal compilers

and QL/17, an inquiry language that works with the

TOTAL data base management system. Not

all

of

these

features can

be

used on the 600, because

of

its limited

memory. Summit includes an interactive monitor for time-

sharing, text editor, PRONTO, and the communications

access method.

A

V77

system

is

built around a mainframe chassis with

plug-in slots for additional memory modules, communica-

tions multiplexers, and

I/O

controllers. Generally, a

V77

system consists

of

a mainframe chassis with

V77-800

Sclleduled for delivery

in

July 1979, the

V77-S00

represents

the largest member of the

V77

family. Main memory

ranges from I2SK

to

2 megabytes with an average

cycle

time

of

600

nanoseconds, somewhat faster than the other

V77

models. The performance doubling compared to the

V77-600

is

achieved through the faster memory

(600-

vs.

660-nanosecond

cycle),

faster processor (150-vs. 165-nano-

second cycle), and faster cache memory (150-vs 370-nano-

second

cycles);

cache memory

is

optional for both the

600

and

SOO.

Main memory

for

the

SOO

is

single-port, and can

be

shared

among up

to

four

SOO

systems via memory bus attachments.

The

V77-S00

also features as standard the Megamap memory

management system, which

is

available as an option on

either the

400

or

600

systems. Megamap

is

not available,

or required, with the

V77-200

because main memory

is

limited

to

32K words

(64K

bytes).

Both the

V77-S00

and

600

can be configured

to

support

up

to

256

communications lines. Both utilize the same

Data Communications Multiplexers and

line

adapters, and

can support the same peripheral and

1/0

devices (including

up

to

4S00

megabytes

of

disc storage each).

Not

all

of

the software available on the

SOO

with the

new

Summit operating system

is

available

on

the 600. For

example, the

600

loaded with the Summit system cannot

support the Fortran

77

compiler.

V77-600

The foundation of the

V77-600

architecture

is

a dual-

port memory and up to three busses that permit variable,

or even customized, arrangements of data transfer paths.

Each 16K-, 32K-, or 64K-word memory module has an

"A" port and a

"B"

port.

In a typical single processor arrangement, only the "

A"

port

is

used.

It

is

attached to the Memory Bus A and

is

the

only access to memory. The bus

is

also attached to a 370

nanosecond Cache Memory. In addition to being a funnel

for

all

transfers to and from memory, the Cache Memory,

with 1024 words,

will

have the most recently used instruc-

tions and data readily available

for

processor use; the

information

is

accessible in little more than half the time

required to retrieve

it

from the

660

nanosecond main

memory. The Cache Memory

is

also attached to the Meg-

amap and the Option Board features. The latter feature,

in turn,

is

attached to one

of

the two processor lines. Data,

instructions, and memory address commands traveling from

the processor to memory "functionally" go through the

gauntlet of: processor

to

Option Board, Option Board

to

Megamap for any address extension necessary, then to the

Cache Memory, to the Memory

Bus

A, and finally into

memory through Port

A.

Information traveling from mem-

ory to the processor runs the same gauntlet in the other

direction.

The largest memory addressable

by

the basic instruction

repertoire i'i 32K words. When the memory size

is

greater

than 32K, the Megamap option i'i required. This memory

management feature divides physical memory into I K-byte

pages.

The

I/O

Bus

is

attached

to

I/O

device controllers. Con-

trollers are provided for communications lines, disc drives,

magnetic tape drives, diskette drives, printers, and display

stations.

Data being transferred between a device attached to the

I/O

Bus

and memory can be transferred directly or through

program control (interrupt). The method

is

dependent on the

type of controller employed and

VT

AM software support.

Direct memory transfer

is

accomplished without the time-

consuming processor intervention. Devices that cause inter-

rupts can be assigned one

of

eight priorities for processor

servicing.

The Cache Memory

is

an optional feature that the manu-

facturer estimates increases the transfer rate

of

90

percent

of

the data between memory and the processor.

The mainframe chassis

is

available in two sizes. The seven-

inch high version accommodates the control panel, the

processor,

256K

words of memory, and the Option Board

and provides accommodation for the

I/O

and Memory

Expansion Chassis. Seven bus slots are required to accom-

modate the above features. The 14-inch high version

is

identical

to

the 7-inch version, except that an additional 9

slots are available for certain options, such as memory,

Megamap, Cache Memory, and Floating-Point.

When more memory than can be accommodated

ill

the

mainframe

is

required, the Memory Expansion Chassis

and system power supply are required.

A System Console and a Real-Time Clock are integral

with the basic V77-600.

In a two-processor arrangement, memory can be shared.

A Memory Bus

is

attached to each

of

the two memory

ports. Each bus

is

attached to one.

of

the two processors

(via Cache, Option Board, etc.). Each processor can be

simultaneously accessing different modules ofmemory under

this arrangement. When both processors attempt to access

the same module simultaneo'lsly, the processor whose

Memory Bus

is

attached to Port A

of

the memory

will

receive first priority. The bus attached

to

Port B

will

always have to wait until the Port A access

is

completed.

V77-200

The

V77-200

is

designed for applications requiring SK, 16K,

or

32K

16

bit words of main memory. The memory size

limitation eliminates the need for the Megamap feature.

V77-200

main memory

is

single-port. Cache memory, Writ-

able Control Storage, and Priority Memory Access are not

supported

by

this model; Direct Memory Access and the

system console are standard. Using a 4-Channel Interface

Controller, the

V77-200

can be connected

to

a V77-600.

The

V77-200,

then, can

be

utilized

as

a tightly coupled

front-end processor to the V77-600 host.

V77-400

The V77-400, although equipped with a slower speed proc-

essor,

is

functionally the same as the V7-600, except that it

does not support Cache Memory, Priority Memory Access,

or

Floating-Point. A system console

is

included with the

basic system.

This model supports a dual port memory controller and can

share memory with a

V77-600,

thus lending itself to use as a

tightly coupled front-end communications processor

to

a

V77-600

host.

CONN ECTION TO HOST COMPUTER

When a

V77

is

used as a front-end processor and another

V77

is

the host, the front-end can merely place data destined

for the host into memory shared

front-end. Conversely, data destined for a communications

Memory Bus attached

to

the non-shared memory.

Software modules are available which allow

controller units. The maximum system configurations

for the

600

and 800

of

256 lines assumes that each system

is

devoted almost entirely

to

communications processing.

The addition

of

I/O

controller units

will

proportionately

decrease the number

of

multiplexers (and lines) that can

be configured.

SOFTWARE

The

V77

operating system'is VORTEX, a multi-program-

ming, dhc-oriented system.

For

systems with a minimum

of

16K and a maximum

of

32K words

of

memory, VORTEX I

is

the operating system. VORTEX II

is

used for systems with

more than 32K words

of

memory. The difference

is

that

VORTEX

II

provides software support for the Megamap

feature necessary

to

develop addresses greater than 32K.

The Summit operating system, announced

in

December 1978,

is

an expansion

of

VORTEX II.

It

is

designed to operate

Processors

Sperry Univac

V77

Family Communications Capabilities

on either the

V77-600

or

V77-800 system, although each

will

also function with VORTEX II. Integrated within

Summit are the PRONTO transaction manager, a modifi-

cation

of

the VORTEX Telecommunications Access Method

(VT AM), an interactive monitor for time-sharing applica-

tions, and the capability

to

perform all

the

program

development and operating system functions that

were

available with VORTEX II. Communications

is

enhanced

with Summit

by

the addition

of

separately-priced modules

which include a DCA package offering

V77

models the

capability

of

communicating with Univac

90

or

1100

series

computers

in

a distributed Communications Architecture

environment. A complete DCA package

is

available which

provides support for a mix

of

transaction and interactive

processing and remote job entry. Other options available

with Summit are the TOTAL data base manager, QLf77

(an inquiry language which works with TOTAL), and both

Pascal and Fortran

77

compilers.

Utilizing the Megamap memory, VORTEX II or Summit

divides main memory into SI2-word pages. Each user

application can utilize up to

64

pages

of

memory, or

32K

words. This limitation

is

imposed

by

the maximum self-

relative address containable in the instruction format. The

Megamap system keeps track

of

the actual memory locations

of

each user page. Importantly, the pages for a particular

user application need not be contiguous pages.

A set

of

modules that handle the telecommunications func-

tion are designated the Vortex Telecommunications Access

Method

(VT

AM). One module, the Communication Con-

trol Module,

is

required

to

drive the communications con-

trollers. A copy of the module

is

required

for

each type

of

communications controller attached to the system. For

instance, the Data Communications Multiplexors would

require a copy

of

this module to operate them. This

module performs the

I/O

handler function.

Another

VT

AM module

is

the Terminal Control Module.

This module performs the terminal handling function for

each type

of

terminal attached

to

a specific line (Line

Adapters).

The Network Control Module performs the logical link

function and provides the operator with an interface to the

communications system. Using a Network Dermition Lan-

guage, the operator can instruct this module to alter the

network configuration. In this manner, lines or terminals

can

be

dropped or added, logical links can be rerouted, and

the status of a line can

be

ascertained.

Univac provides application packages that interface with

VT

AM. Included are:

•

HASP

/RJE-

Permits a

V77

to

serve as a remote work

station for an IBM 360/370.

•

TEN04-

• UT

200-

•

PRONTO-

Emulates a Univac 1004 terminal.

Emulates a

CDC

UT200 User Terminal.

Provides interface control between com-

munications and

file

access function.

It

can mUlti-task transactions and access

files

sequentially, index sequentially, or

via TOTAL. TOTAL

is

the VORTEX

data base management system. PRON-

TO permits a

V77

to

operate

as

a host

to

buffered asynchronous

or

IBM 3270-

type terminals. A

V77,

with PRONTO,

can also operate as a communications

interface between an IBM 360/370 and

mUltiple terminals.

Programming languages offered included COBOL, FOR-

TRAN,

RPG

II, and

DASMR

(a macro assembler). MIDAS

is

the microassembler used when the system includes the

Writable Control Storage option.

MEMORY

Within the V77-600, dual-port memory can be expanded

to two million bytes in 128K-byte increments.

Within the V77-400, dual-port memory can be expanded

to

SI2K bytes in 64K-byte increments.

Within the V77-200, 16K, 32K,

or

64K bytes of single-port

memory is available.

The Memory Management System, Megamap,

is

required on

the V77-400, 600, and 800 when memory exceeds 32K words.

This feature, along with software support provided in

VORTEX II, provides the addressing scheme that permits

attachment

of

over one million memory words, equivalent

to

over.

two million bytes.

Cache Memory

is

available for the V77-600 (370-nano-

second cycle time, and V77-800 (ISO-nanosecond cycle time).

Cache Memory

is

interjected between the processor and

main memory and can almost double the speed for 90

percent

of

the processor/main memory transfers. This

is

accomplished by continually loading the

1024

words

of

this

special memory with the most recently used instructions and

data in anticipation

of

use

by

the processor.

Available only on the V77-400, 600, and 800, the Writeable

Store (WCS) option permits user incorporation into firmware

subroutines of instructions that are frequently used in

his

applications

or

that are time critical. When frequently used

instructions are microcoded, the overall overhead

of

the

system

is

reduced. WCS

is

available for the V77-400 and 600

in a single 1024-word increment. Up

to

12K bytes of WCS

is

available for the V77-800. The V77-800 can

also

support

2K bytes

of

PROM

in conjunction with WCS.

PROCESSOR FEATURES

The Priority Interrupt Module feature permits assignment

of

proc(!S!;ing

priority to up to

64

interrupt-type devices attached

to the

I/O

Bus. Each device can be assigned one

of

eight

priorities. The registers to store the mid-stream processing

of

a lower priority device in order

to

service a higher-priority

interrupt are included. Each module occupies one slot on the

Cardframe Chassis.

When direct memory access devices are attached

to

the

I/O

Bus, the Block Interlace Controller feature

is

required. This

feature

will

accommodate up

to

ten devices. A maximum

of

eight Block Interlace Controllers can

be

added to one

system and

will

handle a total of eighty devices. Each

controller occupies one slot on the chassis.

The Priority Memory Access feature provides for high-speed

data transfer between discs (or special interfaces) and mem-

ory. This feature provides direct memory transfer

of

blocks

of

data over four channels. Each channel has a hard-wired

priority. Although two

disc

units can

be

physically attached

to a channel, only one unit can be active at a time.

The

PMA

feature requires the presence

of

Block Transfer

Controller. A maximum

of

four such controllers are allowed,

with each controller occupying three slots

of

the Card-

frame Chassis.

PERIPHERAL DEVICES

Up

to

four magnetic tape drives can be added to one mag-

netic tape controller, which occupies six slots

of

the

I/O

Cardframe Chassis. The units support 9-track,

800

bpi

recording at either

25

ips or 37.5 ips with read after

write. Drives with 1600 bpi and 800/1600 bpi formats that

operate

at

45

ips and

75

ips are also aVailable.

Family Communications Capabilities

The

powerful

V77-600

in

the background, allowing other

family members, the

V77-400

with the pedestal cabinet and the

V77-200

held by the model,

to

MANAGEMENT

SUMMARY

Evolution

of

the

V70

series minicomputers, which have

been marketed

by

Varian since

1974,

has produced the

V77

family, with more memory and options than pre-

viously available. The

V77

family can support slightly

over one million words (or over two million bytes)

of

main memory.

The intermediate-speed and highest-speed

V77

models

are attractive from a communications standpoint because

they support dual-port memory. The dual ports permit

two local processors to share or have access to the same

memory module. When a

V77

is

used

as

a front-end to

another

V77

host, shared memory between them

gives

the

host immediate access to data stored by the front-end

from communications lines. The extra step

of

moving

data from the front-end to the host's memory

is

elim-

inated. Similarly, data released by the host for front-end

processing

is

available to the front-end without first

having to be transferred to the front-end memory. Shared

memory arrangements also permit establishment

of

a

network where a secondary host

or

a secondary front end

is

able to access data awaiting prime processor action

CONFIGURATION

The

V77

family

of

minicomputers includes three basic

models, each with a different processor, to provide three

levels

of

price and performance. The highest-speed

V77-600

is

based on a

165

nanosecond,

64

bit microword processor.

This processor

is

essentially an improved version

of

the

V76

model

of

Varian's

V70

minicomputer series. The

V77-

600

can execute a macroinstruction in two

or

three micro-

cycles.

The intermediate-speed

V77-400

has a

220

nanosecond,

32

microword processor. The processor

is

a

new

Varian de-

velopment for the

V77

family that executes a macroinstruc-

tion

in

three

or

four microcycles.

The slowest-speed

V77-200

has a

165

nanosecond,

24

bit

microword processor. This processor

is

also newly developed

and requires two

to

three microcycles to execute a macro-

instruction.

Main memory for all three basic models features the same

660

nanosecond

cycle

time and

16

bit word organization.

The ability to

give

special high-priority direct memory

access to disc

mes,

at transfer rates up to

604K

(16

bit)

words per second, should be of interest to networks that

require especially heavy access to random

meso

While no feature

is

yet provided that supports a bit-

oriented line control protocol, Varian has stated that it

intends to support SDLC. Binary Synchronous Commu-

nications protocol

is

supported at speeds up to 50,000

bps. Other control protocols are supported

at

speeds up

to

9600

bps.

The utilization of different minicomputers for each of the

three models of the

V77

family

is

a departure from the

V70

product line where essentially one minicomputer

served almost

all

models.

The offering of predefined starting configurations simpli-

fies

system building within an architecture that

is

already

devoid

of

complicated exceptions and conditions, making

it easy to tailor a configuration.

The destiny

of

Varian Data Machines is, at the moment,

being determined in the board rooms

of

Varian Asso-

ciates and the Sperry Rand Corporation. While both

parties explore the possibility

of

Varian Data Machines

becoming part of the Sperry Univac organization, the

industry can do little but wait, watch, and calculate the

odds for a June wedding. 0

~

In addition to the processor dift'erences, the models differ

in

their: maximum allowable memory

size;

internal data

transfer methods; firmware options; number

of

memory

ports; and supportability

of

cache memory, memory parity,

memory protect, and floating-point options. The bask: pro-

cessor models with certain options are offered with unique

sulHnodel numbers.

For

instance, a basic

V77-600

with

Priority Memory Access is designated the

V77-601.

Single and multi-line communications controners are avail-

able to handle synchronous and asynchronous lines

in

either

full-

or

half-duplex modes with speeds up to

9600

bps.

Binary Synchronous Communications protocol lines are

supported up to

50,000

bps. Standard interfaces include

RS232C, CCITT

V24,

20

ma and

60

ma current loop and

telegraph nefwork-compatible.

VTAM

is

the telecommunications access method software

for the V71s operating system, VORTEX. VTAM modules

drive the c.ommunications controners, handle the com-

munications lines for supported protocols, and provide for

network control and modification.

V77

-600

Architecture

The foundation

of

the

V77-600

architecture

(see

Figure

1)

is a dual-port memory and up to three busses that permit

variable,

or

even

customized, arrangements

of

data transfer

paths. Each

16K,

32K,

or

64K

word memory module has

an "A" port and a

"B"

port.'

In a typical single processor arrangement, only the "A" port

is used.

It

is

attached

to

the Memory Bus A and

is

the

only

aCcess

to memory. The bus is also attached to a

370

nanosecond Cache Memory. In addition to being a funnel

for all transfers

to

and from memory, the Cache Memory,

with

1024

words,

win

have the most recently used instruc-

tions and data readily available for processor use; the

information is accessible

in

little more than half the time

required

to

retrieve

it

from the

660

nanosecond main

memory. The Cache Memory

is

also attached to the

Meg-

amap and the Option Board features. The latter feature,

in

turn, is attached

to

one

of

the two processor lines. Data,

instructions, and memory address commands traveling from

the processor to memory "functionally"

go

through the

gauntlet of: processor to Option Board, Option Board to

Megamap for any address extension necessary, then to the

Cache Memory, to the Memory

Bus

A, and fmally into

memory through Port

A.

Information traveling from mem-

ory to the processor runs the same gauntlet in the other

direction.

The largest memory addressable

by

the basic instruction

repertoire

is

32K words. When the memory size

is

greater

than 32K, the Megamap option

is

required. This memory

management feature

is

capable

of

expanding the address-

able space to

1,048,576,

which

is

the maximum amount

of

memory that can

be

attached to the system.

In addition to the processor and the Cache Memory being

attached

to

the Option Board, the

I/O

Bus and the Memory

Bus

B are attached. In this arrangement, the Memory

Bus

B

is

a misnomer.

It

is

really a bus providing a direct con-

nection between the processor, the Priority Memory

Access

(PMA) option, and the Option Board (for access to mem-

ory). The

PMA

provides four channels for attachment

of

high speed

I/O

interfaces

or

devices such as disc units. With

the PMA, data can be block transferred between disc and

memory without the

discs

having to contend for access on

an equal footing with the other I/O's. The four channels

have hard-wired priorities for servicing

by

Memory Bus

B.

The second processor line

is

attached to Memory Bus B

for direct control

of

disc transfers.

The

I/O

Bus

is

attached to the Option Board and back-

planes in the

I/O

Cardframe, Chassis. The Cardframe

Chassis has

24

slots for attacliment

of

I/O

devices. An

Expansion Chassis provides

aD,

additional

24

slots. The

chassis have multiple standard )Jackplanes; various Con-

nector Planes are available, dependent upon the

I/O

devices

to be added to the system.

Th~.

controllers necessary to

drive the selected

devices

are attached to the Connector

Plane and to the

devices

themselYes.

Controllers are pro-

vided for communications lines, disc drives, magnetic tape

drives, diskette drives, printers, and display stations.

Data being transferred between a device attached to the

I/O

Bus and memory can

be

transferred directly

or

through

program control (interrupt). The method

is

dependent on the

type of controller employed and VTAM software support.

Direct memory transfer

is

accomplished without the time-

consuming processor intervention. Devices that cause inter-

rupts can

be

assigned one

of

eight priorities for processor

servicing.

Up

to

64

such devices can be so assigned.

The Cache Memory

is

an optional feature that the manu-

facturer estimates increases the transfer rate

of

90

percent

of

the data between memory and the processor. When the

cache memory

is

not included

in

the configuration, Memory

Bus

A

is

connected to the Option Board & Megagroup

features.

The mainframe chassis

is

available

in

two sizes. The seven-

inch high version accommodates the control panel, the

processor,

256K

words

of

memory, the Option Board, and

fans and provides accommodation for the

I/O

and Memory

Expansion Chassis. Seven bus slots are required

to

accom-

modate the above features. The 14-inch high version

is

identical to the 7-inch version, except that an additional 9

slots are available for certain options, such as memory,

Megamap, Cache Memory, and Floating-Point.

When more memory than can be accommodated

in

the

mainframe

is

required, the Memory Expansion Chassis

is

required. The System system power supply also requires

its own chassis.

A Teletype/CRT controller, a Programmer's Console and a

Real-TIme Clock are integral with the basic

V77-600.

In addition to the vendor supplied microcode, the user can

optionally add up to

4096

words

of

his own microcode to it

64-bit, 190-nanosecond Writable Control Store.

of

the two memory

ports_

Each bus

is

attached

to

one

of

the

two processors (via Cache, Option Board, etc.). Each pro-

cessor can

be

simultaneously accessing different modules

of

memory under this arrangement. When both processors

attempt

to

access

the same module simultaneously,

the

pro-

cessor

whose

Memory

Bus

is

attached to Port A

of

the

memory

will

receive first priority. The bus attached to Port B

will

always have

to

wait until the Port A

access

is

completed.

To illustrate the variability of arrangements possible, the

PMA

in

Figure 2

is

not attached

as

described

in

Figure

Instead,

it

is

attached to the same bus that

is

co~eeted

to memory. In Figure

the

I/O

Bus has been

given

the

second line to the processor and, therefore, enjoys the kind

of

processor service that the PMA enjoyed in Figure

V77-200

Architecture

The

V77-200

is

designed for applications requiring

8K,

16K,

or

32K

16

bit words

of

main memory.

The

memory

size

limitation eliminates the need for the Megamap feature.

V77-200

main memory

is

single-port. Cache memory, Writ-

able Control

~torage,

Programmer's Console, and Priority

Memory

Access

are not supported

by

this model; Direct

Memory

Access

is

standard_

Using

a 4-Channel Interface

Controller, the

V77-200

can be conneeted to a

V77-600.

The

V77-200,

then, can be utilized as a tightly coupled front-end

processor to the

V77-600

host.

V77-400

Architecture

The

V77-400,

although equipped with a slower speed pro-

cessor,

is

functionally the same

as

the

V7-600,

except that it

does not support Cache Memory, Priority Memory

Access,

Floating-Point,

or

the Programmer's Console.

This model supports a dual port memory controller and can

share memory with a

V77-600,

thus lending itself to use

as

a

tightly coupled front-end communications processor

to

a

V77-600

host.

CONNECTION

TO

HOST COMPUTER

When a

V77

is

used as a front-end processor and another

V77

is

the host, the front-end can

merely

place data destined

for the host into memory shared

by

both the host and the

front-end. Conversely, data destined for a communications

line

is

placed

by

the host in the shared memory. Control

words resident in the shared memory and constantly moni-

tored

by

both processors serve

as

a means for inter-

processor communications. Alternatively, a conventional

V77-

V77

Channel Interface can conneet the front end and

host.

All memory need not be shared. Each processor can have

one Memory

Bus

attached to the shared memory and

anQther Memory Bus attached to the non-shared memory.

TRANSMISSION SPECIFICATIONS

Single-line and multi-line controllers are offered for support

of

communications lines.

The

communications controllers

are mounted

in

the

I/O

Cardframe Chassis or its expansion

chassis. Four Data Communications Multiplexors (DCM)

are offered

t~

support

8,

16,

32,

or

64

lines.

The four

DCM's come

in

two versions; one version

is

for systems

with the Megamap feature, and the second

is

for systems

without Megamap. Eight types of Line Adapters are pro-

vided for attachment

current loop interfaces are supported. One adapter provides

BSC protocol, and the others are for other character control

protocols. Where applicable, the required character control

protocol and line speed can be selected programmatically.

All Line Adapters, except the BSC Line Adapter, can

support

up

to four lines operating at up

to

9600 bps. The

BSC Line Adapter can support only one line at up to

50,000 bps. Table

2,

Line Adapters for the

Data

Commu-

nications Multiplexors, lists the line interfaces offered.

Each

Data

Communications Multiplexor requires four slots

in the Cardframe Chassis. Since the chassis has

no

back-

plane, a specific connector plane, the

Data

Communications

Connector Plane (DCM),

is

required

to

provide the appro-

priate connections for the four slots. Two

of

the slots pro-

vide the electrical connection for the multiplexor, and the

two remaining slots provide the connection for two Line

Adapters.

For

non-BSC protocol lines, two adapters so con-

nected support eight communications lines. When the Data

Communications Multiplexor

is

for

16,

32,

or

64

lines,

additional Line Adapters must be mounted in the chassis. A

second specialized connector plane, the Line Adapter Con-

nector Plane (LAD),

is

required

to

provide the electrical

connection. This backplane can support four Line Adapters,

or

a maximum

of

16

lines. The backplanes each utilize four

chassis slots.

Four

such backplanes and

16

Line Adapters

would

be

required for

64

lines. (See Table 1.)

The Single-Line Controllers, Table

3,

utilize one or three

chassis slots and include their own backplane.

SOFTWARE

The

V77

operating system

is

VORTEX, a multi-program-

ming, disc-oriented system.

For

systems with a minimum

of

16K and a maximum

of

32K words

of

memory, VORTEX I

is

the operating system. VORTEX

II

is

used for systems with

more than 32K words

of

memory. The difference

is

that

VORTEX

II

provides software support for the Megamap

feature necessary

to

develop addresses greater than 32K.

Utilizing the Megamap memory, VORTEX

II

divides main

memory into 512-word pages. Each user application can

utilize up

to

64 pages

of

memory,

or

32K words. This

limitation

is

imposed by the maximum self-relative address

containable in the instruction format. The Megamap system

keeps track

of

the actual memory locations

of

each user

page. Importantly, the pages for a particular user application

need not be contiguous pages. With TSS, the Vortex Time

Sharing Sub-system, up

to

16

users, each utilizing

up

to

64

pages

of

memory, can

be

active simultaneously.

A

set

of

modules that handle the telecommunications func-

tion are designated the Vortex Telecommunications Access

Method (VT AM). One module, the Communication Con-

trol Module,

is

required

to

drive the communications con-

trollers. A copy of the module

is

required for each type

of

communications controller attached

to

the system.

For

instance, the

Data

Communications Multiplexors would

require a copy

of

this module

to

operate them. This

module performs the

I/O

handler function.

Another VTAM module

is

the Terminal Control Module.

This module performs the terminal handling function for

each type

of

terminal attached

to

a specific line (Line

Adapters).

The Network Control Module performs the logical link

function and provides the operator with an interface

to

the

communications system. Using a Network Dermition Lan-

guage, the operator can instruct this module

to

alter the

network configuration. In this manner, lines

or

terminals

can be dropped or added, logical links can be rerouted, and

the status

of

a line can be ascertained.

Varian provides application packages

that

interface with

VTAM. Included are:

•

HASP

/RJE-

Permits a

V77

to

serve as a remote work

station for an IBM 360/370.

•

TEN04-

• UT

200-

•

TSS-

•

PRONTO-

Emulates a Univac 1004 terminal.

Emulates a CDC UT200 User Terminal.

Gives

users

of

up

to

16 local or remote

terminals access

to

interactive time-

shared BASIC, a timeshared editor, and

the VORTEX

II

background

job

stream.

The number

of

users as

well

as their

priority, timeslice, memory allocation,

and other variables are under operator

control.

Provides interface control between com-

munications and

file

access function.

It

can multi-task transactions and access

files

sequentially, index sequentially,

or

via TOTAL. TOTAL

is

the VORTEX

data base management system. PRON-

TO permits a

V77

to

operate as a host

to

buffered asynchronous

or

IBM

3270-

type terminals. A

V77,

with PRONTO,

can

also

operate as a communications

interface between an IBM 360/370 and

multiple terminals. .

~

Programming languages offered include COBOL, FOR-

TRAN, RPG II, and

DASMR

(a

macro assembler). MIDAS

is

the microassembler used when the system includes the

Writable Control Storage option.

MEMORY

Within the

V77-600,

dual-port memory can be expanded

to 1024K words

in

16K,

32K

or

64K

word increments.

Memory can be obtained with

or

without parity. When

parity

is

selected, each

16

bit word has two additional

bits

of

parity, one for each eight bits (one byte).

Within the

V77-400,

dual-port memory can be expanded to

1024K words

in

16K and

32K

word increments. Parity

is

optional.

Within the

V77-200,

single-port memory can be expanded

to

32K

words in 8K, 16K,

or

one 32K word increment.

Parity

is

not available.

The Memory Management System, Megamap,

is

required on

the

V77-400

and

600

when memory exceeds

32K

words. This

feature, along with software support provided

in

VORTEX

II, provides the addressing scheme that permits attach-

ment

of

over one million memory words, equivalent to over

two million bytes.

Available only on the

600,

the 37o-nanosecond Cache

Memory

is

interjected between the processor

..

and main

memory and can almost double the speed for

90

percent

of

the processor/main memory transfers. This is accomplished

by

continually loading the

1024

words

of

this bipolar

memory with the most recently used instructions and data

in anticipation

of

ruse

by

the processor.

Available only on the

V77-400

and

600,

the Writable Control

Store option permits user incorporation into firmware sub-

routines

of

instructions that are frequently used

in

his

applications

or

that are time critical. When frequently used

instructions are microcoded, the overall overhead

of

the

system

is

reduced. Writable Control Storage

is

available

for the

V77-400

in

IOU-word

(32

bits) increments up to

3072

words per system. For the

600,

Writable Control Storage

is

available

in

modules

of

512-,

1024-,

or 2048-word

(64

bits)

increments up to

4096

words per system.

PROCESSOR FEATURES

The Priority Interrupt Module feature permits assignment

of

processing priority to·up to

64

interrupt-type

devices

attached

to

the

I/O

Bus. Each device can be assigned one

of

eight

priorities. The registers to store the mid"stream processing of

a lower priority device

in

order to service a ·higher-priority

interrupt are included. Each module occupies one slot on the

Cardframe Chassis.

When direct memory access

devices

are attached to the

I/O

Bus, the Block Interlace Controller feature

is

required.

This

feature

will

accommodate up

to

ten devices. A maximum

of

eight Block Interlace Controllers can

be

added to one

system and

will

handle a total

of

eighty

devices.

Each

controller occupies one slot on the Cardframe Chassis.

The Priority Memory Access feature provides for high-speed

data transfer between discs (or special interfaces) and mem-

ory. This feature provides direct memory transfer

of

blocks

of

data over four channels. Each channel has a hard-wired

priority. Although two disc units can be physically attached

to

a channel, only one unit can be active at a time.

The

PMA

feature requires the presence

of

Block Transfer

Controller. A maximum

of

four such controllers are allowed,

with each controller occupying three slots

of

the Card-

frame Chassis.

PERIPHERAL DEVICES

Up

to

four magnetic tape drives can be added

to

one mag-

netic tape controller, which occupies six slots

of

the

I/O

Cardframe Chassis. The units support 9-track, 800 bpi

recording at either

25

ips

or

37.5 ips with read after

write. Drives with

1600

bpi and 800/1600 bpi formats that

operate at

45

ips and

75

ips are also available.

Up to four disc drives can be added to one disc controller,

which occupies from one

to

three slots

of

the Cardframe

Chassis, depending on the disc model. Capacity

of

up to

128.9 million

16

bit words per spindle

is

available at a

transfer rate

of

604K

words per second.

Fixed Head Disc

is

also available;

up

to

246K

words per

unit

is

provided. Each controller occupies three slots. The

transfer rate

is

105K

words per second.
