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 user-

oriented 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

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 memory-

resident 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-the-

blanks 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

1

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 communi-

cation 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.

Options-

Graphics 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 (12-

foot)

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 six-

part, 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 132-

column 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

eas-

ily 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 non-

computer-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:

*Trademark

of

Teletype Corporation

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-by-

character 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) user-

specified 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.

Arithmetic Operations. Addition,

subtraction, multiplication,

and

division

of

field

data

can be

performed.

Justification. Numeric

data

may be

left-

or

right-justified with leading

zeros

on

the display and in the

output.

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

4

._----------_._-

......

-

..........

_

....

_

..

..

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 high-

level, English-like language for easy

generation, compilation, and testing

of

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 single-

station

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

•

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/

decom-

pression.

If

the auto-call unit

is

selected, the

771

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 automati-

cally poll

771

and

742 terminals via

the switched telephone network, and

record the received

data

on IBM-

compatible 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.
