INTRODUCTION
The Texas Instruments Silent 700* Model763 memory
send/receivedata terminaland the Model765portable
memory data terminal are designed for easy, versatile
storage and communication of data. The memory
in
both models is implementedusing a revolutionary new
electromagnetic
bubble memory device manufactured
by Texas Instruments. The Model 763 is a compact,
table-top data terminal designed for office use. The
Model 765 is a portable unit furnished with
an attache-
case-like cover to make it useful wherever a standard
telephone and an electrical outlet are available. Both
models are capable of sending
and receiving
information over long or short distances with equal
ease.
A memorydata terminal, usually referred to as an auto-
matic send/receive (ASR) dataterminal,
is equippedto
store data in its memory (magnetic bubble, magnetic
tape, paper tape, diskettes, etc.) from its built-in key-
board or from a communications line (usually a tele-
phone line). The stored datais then availableforediting
(corrections, changes, deletions, additions to the re-
corded text), printing, and for transmission to other de-
vices at much higher speeds than manual keyboard
typing.
For storage of data, the Models
763/765 use the new
Texas
Ins~ruments bubblememory, which has no mov-
ing parts and retains its stored information even with
power switched
off (called nonvolatile memory). The
bubble memory offers important advantages overcom-
monly used paper tape, tape cassette, and diskette
memoriesused in otherdataterminals: Fasteraccessto
its stored data, smaller size, less weight, and lower
power consumption are only a few advantages
of the
bubble memory in the Models 763/765 dataterminals.
Data Terminal Communications
A dataterminal generates codes. The Models 763/765
memory data terminals use the American Standard
Code for Information Interchange (ASCII), commonly
called "as-key",
orthe equivalentC.C.I.T.T. codes. The
codes can
be recorded in the 763/765 bubble memory
and/or transmitted to, and understood by, other de-
vices. The Models 763/765 terminals also understand,
record, and print ASCII or C.C.I.T.T. codes from other
devices such as data terminals, computers, video ter-
minals, and dataloggers.
The code system consists of various combinations of
ones and zeros corresponding to numbers, alphabet
characters, control characters, or symbols. Combina-
DATA TERMINAL

tionsofones and zeros are transmitted and received at
very high speeds as digital signals. The digital signals
areon and
off signals; usuallya one is an onSignal, and
a zero is
an offSignal. Forexample, the alphabet letter
"U" isa series ofon off on off on off on (imagine flipping
a lightswitch on and off) or 101010
1.
How are the digital signals transmitted from one device
to another? Ifthedistanceisabout15meters(50feet)
or
less, cables are used to interconnect the devices and
the devices are referred to as hard wired together
(directly cabled). For example, when a data terminal is
connected to a computer for use
as the computer con-
sole, it is usuallyhardwiredtothe computer.

Longerdistances require the use of telephone lines, and
the digital signals (ones and zeros) must be converted
to analog signals (the human voice
is an analog signal).
The device used to convert digital signals (from and to
data terminals) to analog signals (to travel over the
telephone lines) is called a data set or a modem
(for modulator/demodulator). The modem can be
built into the data terminal or external to it, and
a modem is required
at both ends of the telephone
lines.

Also available for communicating analog signals over
telephone lines is the standard telephone handset.
However, the digital signals from the dataterminal must
be converted to sound signals (called VOice-grade
signals) for transmission over the telephone lines. The
device that converts digital signals to sound and vice
versa
is called an acoustic coupler which can be built
into the dataterminal (as in the Model 765) orexternalto

General Operating Guidelines and Notes
1. References in this manual to data terminal or
terminal apply to both Models 763 and 765unless
specifically stated otherwise. The two models dif-
fer basically
only in their intended use and built-in
communications circuits. The Model 765 is de-
signedforportablefield usewith its integral acous-
tic coupler mated to a telephone handset. The
Model 763 is intended for table-top, hard-wired,
nonportable applications.
2. Press means momentarily push down the desig-
nated keyboard key and release it. Depress
means push down a key or switch until it locks.
Press andhold means push down a key and hold
it down while performing some otherstated action
(similar to the SHIFT key on a standard
typewriter).
3. Communications line or simply line refers to the
cable
or telephone line over which the terminal is
"connected" to anotherdevice. On line meansthe
terminal is set so as to transmit
and receive coded
data over the communications line. Offline (also
called local) means the terminal is electronically
disconnected from the communications line.
4. Press the PAPER ADVance key to advance the
paper (the printhead does not move). This key
does not generate a code, and its action is neither
transmitted
nor stored in memory. Press and hold
the PAPER ADV key to feed the printing paperout
of theterminal.

5. Press the SKIP key to move the printhead to the
leftmargin and advance the paper(equivalentfoa
standard typewriter carriage return).
Or you may
press both the LF (line feed) and CR (carriage
return) keys to generate the equivalent to a
standard typewritercarriage return.
6. Note the operating CAUTIONS throughout this
manual. Most notably, do not operate the data
terminal without printing paper: the platen and
printhead could be damaged, voiding the
warranty.
7. The Models 76317E25 terminals arenormally in the
ASR mode. To enter the COMMAND mode, sim-
ply press the CMD key. The terminal will stop
whatever it maybe doing to awaityourcommand,
so be careful not to press the CMD key accident-
ally.
8. Theword record is used extensively inthis manu-
al to define two entirely different terms. Ref-cord
refers to a contiguous block of data stored in the
memory. Re-cord'
(as' in RECORD ON,
RECORD OFF, etc.) refers to the act of storing
data in memory. Although no accent marks are
used in the text to distinguish the meaning
of the
word, the context in which it is used should signify
its intended meaning.

loaded: Damage to the printhead
and platen could result, voiding
the warranty.
• Take care when first operating
the terminal after it has been
stored at temperatures exceed-
ing the normal operating range.
The terminal is designed to oper-
ate between
10°C and 40 °C (50
of and 104 OF) and should be
allowed to come within this oper-
ating range before power
is ap-
plied. Operation of the terminal
outside
of this range may cause
malfunctions.
• After switching power off, wait at
least 15 seconds before switch-
ing poweron again: Malfunctions
may result.
1. Check that the power cord is plugged into the
terminal and the wall outlet. Check that paper is
loaded (see
Loading Paper).
2. To switch the terminal ON, set the power switch
(located on the top right rear of the terminal)
toward the rear of the terminal. The terminal will
respond by moving the printhead over to the left
margin and typing the message "READY" fol-
lowed by two characters that indicate the revision
number
of the terminal internal programming. The
word "PROM",followed by anumber, also maybe
printed to indicatethe model ofthe programmable
read-only memory (PROM) installed in your
terminal.
3. To switch the terminal OFF, set the power switch

modes of terminal operation. The use of these special
purpose keys
is described in Section II of this manual.
The control characters generated in conjunction with
the
CTRl key are shown in Section IV and Appendix A.
CMD (Command) Key
The 763 and 765 have two modes of operation: com-
mand and interactive. Pressing the orange CMD key on
the upper right corner of the keyboard sets the terminal
to the command mode and causes the COMMAND
indicator lamp to light. Pressing the CMD key and then
the SKIP key returns the terminal to the interactive
mode. These modes of operation are described more
fully inSection II ofthis manual.
UPPER CASE Lock Key
The UPPER CASE lock key is very similar to the shift
.lock on a standard typewriter, with one exception: when
the terminal is
in UPPER CASE lock, it still requires the
use
of the SHIFT key to print shifted nonalphabetic
characters. For example, even with the UPPER CASE
key depressed, the SHIFTkey is still requiredto printthe
percent (%) symbol. The UPPER CASE lock key re-
mains active until it is pressed again to release
it.

Section I
SKIP Key
The SKIP key performs the same function as acarriage
return on a standard typewriter. Pressing the SKIP key
causes the paperto advance and the printhead to return
to the left margin. When the terminal is
ON LINE, the
SKIP key also creates an end-of-line (EOl) code which
is added to the data being transmitted or recorded.
Additional usesofthe SKIP keyare detailed
in Section II
ofthis manual under EDIT Mode.
PAPER ADVance Key
The PAPER ADV key will advance the paper one line
each time it is pressed. If it is pressed and held, it will
cause the paper to advance continuously until it is
released. The PAPER ADV key does not generate a
code that can be stored
in memory ortransmitted.
LF (Line Feed) Key
The line feed (IF) key causesthe paperto advance one
line. The printhead doesnotmove. This key generates a
code which can be transmitted and/or stored
in
memory.
CR (Carriage Return) Key D LEi) [
The carriage return (CR) key causes the printhead to
move to the left magin. The paper does not line feed.
This key generates a code which can be transmitted
and/or stored in memory.
Programmable KEY
_81
The key labeled KEY causes the terminal to processthe
single character for which the operator has pro-
grammed
it. The definition for the KEY may be changed
by a simple command entered through the keyboard.
Your terminal may already
be set for a special function:
referto the Systems Manual for
detail~.
SHIFT Keys [SHIfT] ($tilFY )
The SHIFT keys perform the same function as the
SHIFTkey on astandard typewriter. Pressing and hold-
ing either SHIFT key, in conjunction with any printable
characterkey, causes printing ofthe appropriate upper-
case alphabet letterorthe symbol atop the keycap. For
example, pressing the SHIFT and 4 keys will generate
the
"$" sign.

Section I
Repeating Keys
If orie of the following keys is pressed and held longer
than 1/2 second, their action or character will continu-
ously repeatuntil the key is released:
•
Spacebar
• Underscore (_) key
• Minus/hyphen (-) key
• Period (.) key
• Asterisk (*) key
• C~ARacterforward space/backspace key.
DoubleSpace Printing
Off-line double line spacing maybe obtained simply by
pressing and holding the FCTN (function) key while
quickly tapping the PAPER ADVance key. All subse-
quent lines will be printed double space. To return to
single space printing, again press the FCTN and
PAPERADVance keys.

The Commands
The Models 7631765 memory terminals accept certain
English-text commands which enable the operator to
modify the operational parameters of the terminal,
manipulate data and how it is stored
in the terminal
memory, andprintouttheterminalstatusdisplay. Other
commands cause the terminal to test itself and auto-
maticallyexecute commands stored in memory.
The commands afford the user the ability to configure
the terminal for a wide range of diverse applications.
The ability to modify communications parameters en-
ablestheterminal tocommunicatewith severaldifferent
types of networks using the appropriate telecommuni-
cations conventions foreach.

Interactive Operation
Interactive (on-line) operation describes the ability of
the terminal operator to communicate with the terminal
itself and, through the terminal, with remote data proc-
essing equipment.
Communications procedures may differ from one data
terminal installation to another, depending
on the type of
data processing devices with which the Models 763/
765 may be communicating. Therefore, specific step-
by-step instructions must be tailored for your communi-
cations network. General operating principles appli-
cable to
all communications networks employing the
7631765, however, are described in Section IV,
Terminal Communications.
Model 763
The Model 763mustbeconnected to acommunications
line before on-line operations are possible. See the
Systems Manual for cabling information, and refer to
Section IV of this manual for more details.
Model765
Operation of the Model 765 using its built-in acoustic
coupler requires only a standard telephone set and an
electrical outlet. Detailed instructions for using the
acoustic coupler are contained in Section IV of this
manual.
ASR Operation
When the terminal is switched on, it is in the interactive
mode which permits ASR (automatic send/receive)
operations. The terminal will remain in the interactive
mode until the COMMAND mode isentered by pressing
the CMD key. The FCTN key,
in conjunction with the
numberkeys
on the top row ofthe keyboard, are usedto
access different ASR functions such as recording data
into or playing back data from the memory, along with
manyotherkeyboard and communications operations.
7
Section I
KSR Operation
KSR (keyboard send/receive) is also possible in the
interactive mode. KSR is the transmission of any key-
board characters via the communications link
and
printing of any characters received via the communica-
tions link. Some communications links may require your
terminal to transmit its answer-back memory (ABM)
contents before you can commence data transmission
(see Section
III of this manual), and some links may
require use of the "BREAK" to signify that you wish to
transmit
or receive messages. The ABM contents are
triggered by pressing and holding the CTRL key
and
pressing the 1 key, called "HERE IS". The BREAK
signal is generated by pressing
and holding the CTRL
key and the 2 key. Neither of these keys
is labelled as
such on your7631765 keyboard.

Section I
The Terminal Memory System
One of the important features of the Models 763/765 is
theirability to record into and playback information from
theterminal memory. The memory enablesyou to enter
all your information, review it, correct it as required, and
then transmit the information to other data processing
equipment.
Files
To store information (data) in memory, first it is neces-
sarytoestablishareas in memorywherethedatacan be
stored. These areas of memory are commonly called
files. The size ofthe files used in the memorysystem is
determined when the file is created (see below). This
means the file can be made larger or smaller, when
created, depending on the amount of information to be
stored in the file. Just as the memory system is com-
posed of files, the file itself is composed ofrecords.
Records
The term record is used to describe the basic unit of a
file. The records of a file are adjustable in size from 1to
80 characters long at the time the file is created. The
records in separate files maybe different lengths, butall
records in the same file must be created the same
length.
Creating Files
The files used in memory must be created by the
operator, andeach file hasfourparametersthatmustbe
specified bytheoperatorwhen creating thefile. Thefour
factors are FILE NAME, FILE FORMAT, FILE SIZE, and
RECORD SIZE. The following paragraphs describe
each parameter in detail.
File Name
Each file in memory is assigned its own name.This
name must be used
in all future references to the file.
This system is very similar to files in an office file
cabinet. When a particularfile isdesired, one looks forit
under its name. The name of a file
in memory must
contain at leastone letterand no more than sixletters or
numbers total. The file name must begin with a letter.
No spaces are permitted between characters.
File Format
The format of a file determines how the terminal will fill
up the file with the information entered. The two formats
are LINE and CONTINUOUS. Each has its own advan-
tages and disadvantages, as the following paragraphs
explain.
8
Line Format. In the LI NE formateach record in memory
contains onlyone line of data. Forlinesshorterthan the
operator-designated record length, memory area is
reserved between the end of the line of data and the
designatedend ofthe record. Forexample, ifthe record
of a file is deSignated as 72 characters long (80 charac-
ters is the maximum) and the number of characters
entered is only 62, the 10 characters of memory space
between the end
of the line of data (62) and the end of
the record (72) would be reserved; that is, not used.
Although the LINE format is particularly helpful in pre-
paring
and/or editing a data file, it does not provide
maximum use of memory: From the above example, 10
charactersworth of memorywere notused on the single
line.
Continuous Format. In CONTINUOUS format each
designated record is filled before another record is
started. Therefore, each record may contain one or
more lines of data. If the line from the above example
was recorded in a CONTINUOUS-formatted file, after
the 62 characters were entered the terminal would use
the first 10 characters of the next line to fill up the
remaining space
in the record. Although this format is
more difficult to edit than the LINE format, it makes
maximum use of memory. When the data stored in
terminal memory is transmitted to a remote device
through the communications channel or printed by the
terminal printer, it will appear identical, whether re-
corded in LINE orCONTINUOUS format.
File Size
This, simply, is how large the file will be. The size of the
file is measured in lines (records) oftext.
Record Size
Record size is a measure of how many characters will
be contained
in each record of text: The maximum
record size is
80 characters.

SECTION II
DETAILED TERMINAL OPERATIONS
This section describes in detail some of the basic termi-
nal operations. Topics discussed include entry and
definition of commands, setting terminal configuration
parameters, using the ASR functions, and basic text
editoroperations. For additional details
on these opera-
tions, see Section Iofthe Systems Manual.
Terminal Commands
The COMMAND mode of the terminal enables you to
perform a variety of functions to control the operation
and configuration of the terminal. All commands are
in
English-text form which describes to the terminal the
operation you want performed. The syntax (format) and
entry instructionsfor each command are described later
in this section.
Syntaxdiagrams are used in thissection to illustratethe
format of commands; Syntax diagrams are graphs,
always flowing from left to right, which represent the
syntax rules to be followed while entering commands.
An exampie of a syntax diagram is shown in the follow-
ing figure.
In this figure a portion of the COPY command syntax is
illustrated. Following the flow of the diagram from left to
right, we see that the COPY command must precede
any of the other parameters. Then two alternate paths
are available: Each alternative describes a valid syntax
option which may be chosen.
In this example, the KEY
(keyboard) orthe FILENAME options may be selected.
The diagram then continues to flow, from left to right, to
the end of the selected path.
In order to simplify the
syntax diagrams, the required spaces between com-
mand parameters are not illustrated.
Accessing theCOMMAND Mode
The COMMAND mode is accessed by pressing the
CMD key located at the upper right corner of the key-
board. The terminal signifies its entry intothe command
mode by sounding
an audible tone, printing the com-
mand promptsymbol
~ atthe leftmargin ofthe page,
and lighting the COMMAND indicator lamp
in the lower
9
right area of the keyboard. The COMMAND indicator
lamp will remain lit until command mode operations are
completed. Once the terminal enters the command
mode, it will remain in that mode until the desired
command is entered andthe command
is accomplished
bythe terminal.
Pressing the CMD key requests the immediateattention
oftheterminal; care should
be exercised in its use, since
when you press the CMD key, the terminal will immedi-
ately halt any operation in progress, go into the com-
mand mode, and await entry of yourcommand.
Entering a Command
The Models 763/765 provide 14 basic commands. All
commands can be entered using a single line of text
which may be edited during its e.!!!')' using the CHAR
(charact~r backspace) key. The CHAR (forward sp;ce)
and FIELD (forward) keys are disabled during com-
mand entry. Command parameters must
be separated
by at leastone space.
Correction of characters
in the command text may be
donebyusing the printhead as a "characterpointer". By
positioning the pointer below the character to be modi-
fied, the correction is made simply by typing the correct
character. Thus, the CHAR key
is used to position the
--
pOinter (printhead) to the location where a change is
desired, or the FIELD key may be used to return the
--
pointertothe left margin. Wheneverthe pointerposition
is changed, all characters to the right of the pointer will
be erased from the terminal memory and must be re-
ntered.
Once a command is entered, command entry
is termi-
nated by pressing the SKIP keywhich causesthe termi-
nal to executethe specified command. Commands may
be cancelled atanytimeduringentryby usingtheCHAR
--
keyto discardthe previouslyentered command text and
then terminating the command using the SKIP key.
Definition ofCommands
As previouslymentioned, 14 basic commands are used
with theterminal. The 14commandsmaybedivided into
the following five categories:
• File structure display and modification com-
mands, also called file utilities

Section II
• Communications parameter modification
and terminal status displaycommands
• File editing command
• Terminal diagnostics(self-test) commands
• Automatic command execution.
Table 2-1 lists the commands in each category along
with the abbreviations that may be used to enter some
commands. Commands may be entered in uppercase
or lowercasetext.
File UtilityCommands
CREATE -The create file command allocates a con-
tiguous block of memory for a data file. The data file
allocated is identified bythe filename you specify.
Syntax:
• The filename parameter is a required parameter
you must use to assign the name by which a
particular file will be identified in all future opera-
tions. The filename may consist of up to six char-
acters and mustbegin with an alphabet letter(A to
Z). The filename may contain numbers, but may
not contain spaces. Filenames may not be KEY
and TO which are reserved words.
NOTE
When typing the filename, be careful to
type the name exactly the same each
time, in exactly the same character
case (lowercase and capital letters).
For example MYFILE, Myfile, and
myti/e are three differentfilenames be-
cause each is typed using a different
charactercase.

The third parameter specifies the format in which
dataistobe stored in thefile. Theoption L assigns
a line format to the file. The option C assigns a
continuous formatto the file. Seesubsection 3.1.6
of this manualfor an explanation offile formats.
The number-of-records parameter (a positive
number) specifies the maximum numberof physi-
cal records in the file. File size cannot be ex-
panded or reduced once it is created.
The last parameter, record size, specifies the
fixed number
of characters per record. This pa-
rameter is optional and may have a value upto 80
characters per record (including spaces). If no
number is typed, 80 will be assumed.
Once the file is created, file parameters may not be
modifed. However, usingthe
COpy command it maybe
possibletotransferthefile contents toanotherfile ofthe
desired parameters.
In some cases a memory compression may be neces-
sary to obtain sufficient memoryto allocate the file. The
terminal will automatically compress the memory and
will then printthemessage, ONE MOMENTPLEASE, to
notify the operator
of a slight timedelaytocomplete the
memory compression process. No otheroperations are
possible until the compression is complete and the
DONE messageis printed. An example of creating afile
is shown below:

DELETE -The delete file command eliminates all
contents of the file specified from the bubble memory
catalog. Deletion
of locked files is not possible (see the
LOCK command below). The datastored in the file will
be deleted from memory. The area occupied by the
deleted file is available forfuture allocation.
Syntax: IDELETEH.(filename) I
ERASE - The erase file command causes erasure of
the contents
of a file. The data stored in the file will be
lost, but the filename will remain in the catalog for later
use.
Locked files cannot be erased.
Syntax: I

COpy -The copy command offers several options for
copying
data into or out of a file. The COpy command
options are described below:
•
NOTE
The COPY KEYboard to (filename)
and
COPY (filename) to (filename)
commands will "write over" data in the
second (filename) on a line-for-line
basis. Usethe END option to preserve
existing data inthe second (filename).
Copy file to printer with option to print or execute
control characters.
Syntax:
COpy [filename] TO PRINTER
COpy [filename] TO PRINTER CTRL
The CTRL option causes anycontrol characters in
the file to be printed but notexecuted. Ifthe CTRL
option is not entered, control characters will be
executed. Examples
of control characters are LF
(line feed) and CR (carriage return).

SectionII
• Copy file to file with an append option.
Syntax:
•
COPY[filename] TO[filename]
COpy [filename] TO[filename] END
Copying of data between files of differentformats
is possible, but a format change will occur. Also,
whenever copying data from one file to another,
any text editor filler characters will be removed
from all except the last record in the file. (For an
explanation
of filler characteroperation in the text
editorseeEDITMODEdescriptionin the Systems
Manual.) The END option causes the source file
(first filename) to be appended to the contents
of
the destination file (second filename). This option
should not be usedfor continuous-formatted files
ifthe source andthedestinationfilesare the same
file.
Copying from the keyboard to a file. This copy
command option permits entry of data directly
from the,keyboard into a file.
Syntax:
COPY KEY TO [filename]
COpy KEY TO [filename] END
The typing
of each record must be terminated by
pressing the SKIP key. Once all desired data is
entered via the keyboard, the COPY operation
must be terminated by pressing the ENTER key
immediately after pressing the SKIP key. The
END option appends the keyboard entry to the
end ofthe destination file.
• COPY KEY TO FILEt
~ COpy KEY TO FILEt END
CATALOG -The catalog command causes the bub-
blememoryfile catalog tobedisplayedonthe printer.
Syntax:
ICATALOG I
The file catalog information displayed includes the
names
of all existing files and their corresponding pa-
rameters. An
.L displayfollowing the file TYPE (format)
indicatesthe file is in a LOCKed state.
Once all files are listed along with their corresponding
parameters, the amount
of memory remaining is listed
in terms of 80-character ~rds. Thenames of the files
assignedtotheplaybackandrecordfiles alsoare listed.
