Model 771
Intelligent Terminal

Model 771 Intelligent Terminal
The Model 771 Intelligent Terminal
is a single-station, video terminal
system employing diskette storage
and supporting batch and remote
data entry communications to a host
computer or another Series 700
family member. The system provides
a versatile, low-cost solution to
problems associated with distributed
processing applications such as:
•
•
•
•
•
•

Source data entry and update
Local file inquiry and response
Local file maintenance
Data communications
Local printing
Local data preprocessing.

With processing capabilities based
on TI's l6-bit TMS 9900
microprocessor, the 771 terminal
incorporates a 1920-character video
display, dual diskette drives, 24K
bytes of random-access user
memory, integral communications,
and a typewriter-style keyboard in a
functionally designed unit. The useroriented keyboard features separate
numeric pad, cursor control pad,
eight programmable function keys
and eight terminal-status indicator
lights. Also included is a self-test
feature to allow operator
verification of terminal operation.
An alternate configuration provides
a built-in 30-cps, 80-column thermal
printer with a 96 ASCII character
set for a totally integrated system.
For applications requiring
multicopy printing, the TI Model
810 l50-cps printer is available as an
external option with the 771
terminal.

TERMINAL EXECUTIVE
System operation on the Model 771
is supported by a multitasking
executive. This executive provides
operator communications, basic file
management, task scheduling, and
device input / output. The memoryresident executive does not require a
dedicated diskette drive .

TPL 700
TPL 700 is the application
programming language developed
specifically for VDT-oriented data
entry and local preprocessing. It
combines a powerful fill-in-theblanks forms package for data-entry
applications, with a high-level,
English-like procedure language for
data processing applications. The
two mod ules may be used
separately, or the resulting object
programs can be merged or linked
into a total system. Thus, the

advantages of each module can be
realized in any type of applications
task .

Communications
Optional ind ustry-compa ti ble
communications are available for
the Model 771 which supports two
ports for remote communications
via modems. One of the two ports
may be used for serial communication to local EIA devices. The 771
may act as a remote terminal to a
host computer or may act as host to
other remote 771 systems, Model
774 systems, or Model 770s.
Automatic dialing is supported .
Several communications packages
are offered that enable the Model
771 to communicate with host
computers concurrently with
practical use of diskette drives, the
video display terminal, and optional
serial printer or internal thermal
printer.

OptionsGraphics Kit
The 771 's graphics option is an
additional video display character
set providing characters for drawing
lines and graphs or creating special
enlarged characters. This capability
permits the creation of display
formats that closely match printed
forms, improving operator
acceptance.

Printer Kits
The Model 771 Intelligent Terminal
supports the ISO-cps Model 810A
serial printer, which is attached to
the 771 via the local serial
communications port. The Model
810A Printer kit incudes the Model
810 Printer, internal 771 interface,
printer ribbon, and 3.6-meter (12foot) cable. Standard printer
features provided with the kit are
ISO-cps bidirectional printing, 132
characters per line, 96-character
ASCII set, standard character
spacing (ten characters per inch),
slanted ribbon for extended ribbon
life, six or eight vertical lines per
inch (which is software or hardware
selectable), and printing of up to sixpart, high-quality printed forms. In
addition, each is equipped with a
quietized enclosure, which
effectively reduces the operating
noise of the printer. An imbedded TI
microprocessor, other MOS/ LSI
integrated circuits, and TI-built wire
matrix printhead are the keys to
performance and reliable, long-life
operation.
The options package provided with
the Model 810B Printer kit consists
of the basic kit described above with
the addition of compressed print and
vertical forms control features. The
compressed print feature allows the
operator or the application program
to select a character spacing of 10

characters per inch or 16.5
characters per inch. A full 132column width may be printed on a
203.2-mm (8-inch) line length. The
vertical forms control feature
provides up to eight separate vertical
formats that can be programmed
and selected by either the operator
or the application program.

Software
The software available for use with
the Texas Instruments Model 771
Intelligent Terminal provides a
complete set of tools for fast, easy
development of application software
on the 771. The software makes use
of the 771 memory-resident,
multitasking executive to provide
user-oriented support of the
following:
• TPL 700-A high-level language
specifically designed to enable
source data entry and perform
efficient stand-alone data
processing
• Utilities-A complete set of
system support and program
development utilities
• Communications-Includes easily used emulators for IBM 3780,
Teletype* terminals, and Texas
Instruments Model 742 terminals.
User applications programs can
maintain the terminal system under
program control at all times,
relieving the operator of tasks
normally associated with the
operation of a computer system.
The software system provides
capability to obtain automatically a
hard copy of the screen image.

TPL 700
TPL 700 Forms
TPL 700 Forms allows a noncomputer-oriented operator to draw
a form on the video display unit for
subsequent data-entry transactions.
It is not necessary to write a
program. After the form is drawn, a
set of field attributes, which test the
operator entries for each field, are
displayed in a menu fashion for
selection by the form designer. TPL
700 Forms capabilities include:

Interactive Form Design and Field
Attribute Specification. Forms are
drawn by the user on the screen
exactly as the operator will see them,
and validation is specified in a
prompting menu format. Using
graphic characters, display formats
can be created that closely match
printed forms.
Data Validation. Character-bycharacter and field-by-field data
validation is performed; thus, errors
are corrected immediately upon
occurrence and not after an entire
page has been entered.
Range Checking. Fields may be
tested to be within (or without) userspecified limits.
Table Lookup. Entered data can be
compared with user-specified data.
Data Substitution. For example, the
word Tennessee can be substituted
immediately upon striking the T and
skip keys, thereby saving key strokes
and errors.

based on data entered into a field or
in a fixed sequence specified by the
forms designer.
Multipage Forms. Large forms may
be implemented as multipage forms
with data passed between pages.
Invocation of Procedures. For
special cases, procedure language
code may be invoked to handle more
complex validation or processing
requirements.
TPL 700 Procedures
TPL 700 Procedures offers the
application programmer a highlevel, English-like language for easy
generation, compilation, and testing
of processing programs and complex
field-validation programs directly on
the 771. It is fully supported with an
interactive general-purpose editor
for generation and editing of source
code, a compiler for compilation of
source code, and a module linker for
linking procedures to forms, or
procedures to procedures. TPL 700
Procedures capabilities include:

Arithmetic Operations. Addition,
subtraction, multiplication, and
division of field data can be
performed.

• Logical 110 support of sequential
files, relative record files, internal
thermal printer, Model 810
Printers, and EIA-compatible
serial devices

Justification. Numeric data may be
left- or right-justified with leading
zeros on the display and in the
output.

• A powerful ENTER statement,
which provides display of
operator prompts or other data,
input from keyboard with
reformatting and character
validation using defined sets of
characters

Cross-field Validation. Either of two
sets of validation criteria may be
selected for a field, based upon the
data entered in a previous field.
Branching (Fixed and Conditional).
A form may be executed in other
than a left-to-right, top-to-bottom
manner. Form execution may be

Compatibility
The Model 771 Intelligent Terminal
is a member of the Series 700
Distributed Processing Systems
family, which includes the Model
770 Intelligent Terminal, the Model
771 Intelligent Terminal, and the
Model 774 Intelligent Terminal
System. The 770 is a single-station
terminal employing minicartridge
tape storage; the 771 is a singlestation terminal with diskette
storage; and the 774 is a multistation
intelligent terminal system offering
diskette and/ or hard disk storage.
Users of Series 700 systems may
easily and efficiently move from one
member of the family group to
another because of the functional
and operational compatibility
between systems. Compatibility
offers: file structure which is
addressed by all systems; identical
keyboard layout; the same menu
approach to program development;
and familial sharing of TPL 700, the
programming language used by all
systems. Only a minimum of time
and effort is necessary when
changing from one Series 700 system
to another or when mixing models
to fulfill varying needs at different
locations. The family gives a user a
direct path to total systems growth,
growth with minimum effort in the
areas that count:
• Operator. Same keyboard layout
on all three systems which allows
operators the flexibility to move
from one system to another with a
minimum of cross-training
• Programmer. Common TPL700
programming language on all
three systems for easy operation
and consistency. Instruction sets
are virtually identical with
enhancements for diskette or hard
disk systems to take full
advantage of these media

• TPL Source Code. Source code
transportability between the 770
and 771 by means of utility
software and EIA interface cable
(P/N 0993210-0001); diskettes
directly compatible between the
771 and 774
• Data Transportability. Data file
transportability between 770 and
771 using standard communication emulator; diskettes directly
compatible between the 771 and
774.

Communications
Model 771
Communications
Several communications packages
are offered that enable the Model
771 to communicate with host
computers. An interactive utility
program is provided with each
package, which allows a user to
specify the particular set of
communications characteristics
required by the host computer. This
special set of characteristics is
recorded in a diskette file so that
each time the communications
program is loaded into memory
these characteristics may be selected.
IBM 3780 Emulator
The IBM 3780 Emulator package
enables a Model 771 with a
synchronous communication kit
option to communicate with a host
computer, other 771s, 770s, 774s, or
other terminals with corresponding
emulators using IBM Binary
Synchronous Communications
protocol. The emulator is controlled
by a file of commands. Before using
the emulator an operator can build a
command file from a configuration

menu. Alternatively, the command
file may be prepared using the text
editor, or by a user program. The
entire emulator may be activated by
a user program. Special features
include support of transparency
mode, destination device selection,
and space compression/ decompression. If the auto-call unit is
selected, the 771 can operate in an
unattended mode by automatically
dialing user-specified telephone
numbers.

TTY*Emulator
The TTY Emulator package enables
the Model 771 to communicate with
time-sharing services and host
computers that use TTY protocol,
half- or full-duplex up to 1200 bps.
The operator may communicate
interactively using the keyboard and
display or may cause data to be
transmitted from or recorded onto
user-specified files on the diskettes.
The terminal will also operate in an
unattended mode and automatically
answer a phone call from a host
computer.

742 Emulator
The 742 Emulator package enables
the Model 771 to communicate with
the Terminal Polling System offered
by TI, using an asynchronous block
protocol. The TPS will automatically poll 771 and 742 terminals via
the switched telephone network, and
record the received data on IBMcompatible magnetic tape. This
system allows the tasks of data
collection and distribution to be
removed from the host computer,
resulting in a completely
independent terminal network.
