Introduction
INTRODUCTION
OVERVIEW
The Terminal And Plotter User Manual explains how to operate the public computer
terminals and graphics plotters made available by CUCCA (Columbia University Center for
Computing Activities). This manual will help you select the terminal which best suits your
needs, and once having done so, operate it successfully; no knowledge of computing or
computer terminals is required.
Included for those who have never used a computer
terminal before are special introductory sections as well as a glossary. For advanced users,
general technical information and terminal settings are provided for reference.
In addition to the sections on public terminals, instructions are included for using the DEC
WS78 and DECMATE word processors as ASCII terminals to connect to the IBM 3031,
4341, and DECSYSTEM-20 computers. Privately purchased, these word processors are
located in many administrative and academic offices; they are not made available by CUCCA.
Information about the word processors is presented in Appendix I.
Non-technical information relating to terminal usage and availability is detailed in the CUCCA
GUide To Research and Instructional Facilities and the Newsletter, both available in the
Reference Room in the SSIO (Self-Service Input-Output) area (see immediately below for
location). Similarly, for instructions on how to establish communications with the computer
1I0gging in), please refer to the IBM 4341 Log In Procedures sheet or the DECSYSTEM-20
Reference Card, both available in the Reference Room.
Software for setting up many
terminal features is explained in the DEC-20 Reference Card, the IBM 4341 Wylbur Manual
and the CMS Wylbur Technical Note.
Copies of the Terminal And Plotter User Manual are available in the Reference Room,
1 15A, in the SSIO area located in the basement of Uris Hall, or by calling 280-4330.
HOW TO USE THIS MANUAL
Chapter 1, The First Step In Using The Computer, is extremely valuable for new users,
and more advanced users can reference the information about terminal settings as needed
The remaining chapters are divided by category: crt terminals, hardcopy terminals and
graphiCS terminals. Each section contains the technical information you need to use the
terminals, and provides a reference to vendor manuals. Particularly, the subsection SeWng
Up the Terminal, included for every terminal, tells you precisely how to use that terminal
for either the IBM or DEC-20 systems.
A subsection on specific problems, Troubleshoot/ng, outlines the common problems which you might encounter while using a specific
terminal.
Also included is a chapter on repair and installation procedures, an appendix on common
terminal problems and their remedies, and a summary of Hewlett-Packard terminal information. The Table of Contents is very specific, and can refer you directly to the section
you need. If you want to know something very specific and very quickly. e.g., how to

change the parity on the Concept APL-8 terminal, please check the index under the logical
headings, in this case either "Concept-APL, Parity, changing" or "Parity, Concept-APL."
(
SELECTING A TERMINAL
Choosing a terminal depends on need and availability. Crt (cathode ray tube) terminals are
best for programming, text entry and editing, and can print at higher baud rates (speeds)
than hardcopy terminals. Crt terminals have screens similar to a television screen, and are
also referred to as vdt's (video display terminals), although there are some differences.
Hardcopy terminals have print elements but do not have screens, and are used for printing
output, either text or graphics, although they also can be used for programming and editing.
Some terminals combine both video and printing features. Graphics terminals often have
both a video screen and a hardcopy capability. Some hardcopy units are independent of
the crt, some are attached.
All CUCCA terminal keyboards have upper and lower case. CUCCA also provides terminals
with APL character sets, and terminals specifically for graphics. All the terminals described
in this Manual can be used with both the DECSYSTEM-20 and IBM 4341 computers.
SUMMARY OF TERMINALS
New terminals are continually being installed on the Morningside campus. The list provided
below presents a brief description of those currently available.
Further explanations,
information about availability, restrictions, or special equipment are provided in the specific
sections.

NOTES FOR NEW USERS
(
CUCCA offers several kinds of computer terminals to meet different needs. The preceding
paragraphs should familiarize you with the facilities. However, if you have never used a
computer terminal before, a few points might make your adjustment easier and thus
expedite your work,
USING A COMPUTER TERMINAL FOR THE FIRST TIME
If you have never used a computer terminal. it is best that someone show you the basics.
Consultants are available in the 5SI0 area and in Room 272A Engineering Terrace to answer
your questions and instruct you in the operation of the terminals. However, you may wish
to take instructions directly from the Manual.
A HELPFUL COMPARISON
For many new users, the sight of the computer terminal keyboard immediately brings to
mind a typewriter.
This is particularly true of hardcopy terminals, which have print
elements instead of screens. The terminal keyboard closely resembles the keyboard of an
electric typewriter. The alphabetic and numeric arrangements are identical. although some
Backspace, caps lock, and shift keys
terminals have separate number pads as well,
perform the same function as on a typewriter. The carriage return key is located on the
right-hand side of the second bank of keys, as it is on an electric typewriter, and
performs roughly the same function, For further explanations of these keys as they relate
to typewriters and terminals, see the Concept 108 Users Manual pps. 1-4: 1-6, available in
the Reference Room in the SSIO area.

The First Step In Using The Computer
CHAPTER 1
THE FIRST STEP IN USING THE COMPUTER
1.1. PROCEDURES
The procedures for using the computer, listed in order of occurrence, are as follows:
1. Set up the terminal.
2. Turn on the PACX box and make a connection to the system.
3. Log in.
4. Do your work.
5. Log out.
This chapter presents comprehensive information about point 1.
1.2. SETTING UP THE TERMINAL IN THEORY AND PRACTICE
The first step in using most computer systems is to make sure that your terminal is set up
or "configured" for the system you will be using. This includes setting baud rate (terminal
speed!. parity, duplex and other parameters. (See the Glossary on p. 71 for definitions of
these terms.)
There are three distinct aspects to consider when configuring your terminal:
1. The IBM and DEC-20 systems require different values for certain settings,
e.g., parity. duplex etc.
2. Each terminal differs in the kinds of settings which are available and have to
be changed, although most terminals do share some common settings (see
below, section 1.4). For example, not all terminals have a handshake parameter,
but many have a duplex parameter. In short, different terminals have different
features; what you must change on one will not necessarily be present on
another. This will become clear after you have used at least two different
makes of terminals.
3. Each terminal differs in the physical manner in which these values are
established, i.e" older terminals tend to have switches and buttons, while the
newer terminals take typed-in sequences.

The First Step In Using The Computer
1.3. TWO BASIC RULES TO FOLLOW
(
1. Turning on the terminal is the first step in using one; it must be turned on
before it can be configured.
If you do not hear a beep or the screen
brighten after a minute to signify it is powered on, the terminal may be out
of order, although you should check to see that the brightness is turned up
and that the unit is plugged in. For hardcopy terminals you may physically
feel that the power is on if there are no indicator lights, but usually the print
element moves slightly to signal power on.
2. You should configure your terminal for the proper system before making a
connection with the computer through the PACX Gandalf blue box located
near the terminal. Some systems will not recognize changes in settings once
you have logged in, although others will. For PACX information see the 4341
Log In Procedures sheet or the DEC-20 Reference Card.
1.4. COMMON AND IMPORTANT TERMINAL SETTINGS
No matter what terminal or system you are using, you should be aware of the following
three parameters. Please note however that when using graphics terminals and plotters,
certain values must be synchronized with the host terminal. (Baud rates are subject to
change. See below the special note on baud rates, section 1.4.0.1 for further information.)
1. Baud Rate. The speeds appear as 300; 1200; 1800; 4800; 7200; 9600.
(
2. Parity. Parity value names differ for each terminal. but should generally be set
to none for both systems, although some terminals equate mark with none.
Please check each section for the choices.
3. Duplex. The settings will always appear as half or full.
The current values for these settings are:

1.4.0.1. SPECIAL NOTE ON BAUD RATES
The speeds indicated above are the maximum that PACX. not hardwired terminals, can
comfortably support. Development work is currently underway to allow a higher baud rate
for the IBM systems. But at present, 1BOO is the maximum baud rate for terminals
connected through the PACK Users also should note that individual crt's may have built-in
restrictions and therefore may not be capable of operating at the maximum speeds listed
above.
Hardcopy Baud Rates
Unless otherwise indicated, CUCCA's hardcopy terminals must be run at speeds of 300
baud or lower.
Graphics Terminals and Plotters
The HP pen-plotter can be run only at 1200 baud or lower. All other graphics terminals
may be run at the specified baud rate for that system. But the baud rate must be
synchronized with the host terminal. Consult the individual sections.

Concept-APl8
CHAPTER 2
CRT TERMINALS
(
2.1. CONCEPT-APL8
The Concept-APl8 terminal is a microprocessor-based terminal which offers an APl
character set and advanced features such as hardware windowing. which are well
supported by EMACS on the DEC-20. The Concept-APl8 also has a 132 column display
capability.
2.1.1. DOCUMENTATION
Copies of the Concept Manual and Reference Card are available in the Reference Room in
SSIO.
2.1.2. TURNING ON THE TERMINAL
The ON/OFF switch for the Concept is located In the rear center of the terminal. It should
be pressed to the left to turn on the terminal. The brightness knob is located on the left
side of the terminal under the screen housing. Turn it counterclockwise to brighten the
display.
(.
2.1.3. SETTING UP THE TERMINAL -- CONFIGURATION MODE
RESET/STAT Key
The Concept uses typed-in characters rather than switches to set its operation modes.
After turning on the terminal. press the RESET/STAT key on the Cursor Control Pad on the
upper right side of the keyboard (see photograph 2-3). This will display the inverse video
status line (white background with dark lettering), across the bottom of the screen. The
status may display many different values.
Following is a mode line configured for the

2.1.3.1. CHANGING THE SETTINGS
The MULT CODE Key
The values of the settings are changed by issuing MULT CODE character sequences, That is,
each sequence is prefaced by pressing the MULT CODE key located on the Cursor Control
Panel on the upper right side of the keyboard. You press it only once with regular
pressure, and do not hold it down, Unfortunateiy, nowhere is it indicated that the MULT
CODE has been depressed, In MULT CODE sequences, the case of the ietters is extremely
important Often a feature is enabled or disabled depending on the case of the letter, i,e"
upper or lower case, In the following. unless the word shift precedes a letter, be sure to
use the lower case or unshifted form, Shift indicates that you enter a capital letter by
depressing the shift key; If you do not change the setting as desired on the first try, you
must begin the entire sequence over again, I.e., by depressing the MULT CODE key again,
followed by the proper command, The MULT CODE key cannot be depressed repeatedly to
achieve the desired setting,
NOTE: Before attempting the following, you must place the terminal in Programmer Mode,
which is included in the list below, by pressing MULT CODE Shift U, Otherwise, the MULT
CODE .sequences will have no effect. Important settings are in italics,

The Numeric Keypad -- An Easy Way to Setup the Terminal
Note that some of the settings are clearly displayed on the Numeric Pad on the right side
of the keyboard (see photograph 2-3). For instance, "8" corresponds to Duplex, "9" to
Local/Remote, "5" to upper!lower case, and "0" to ASCIi/APL. Those markings on the top
half of the keys indicate that you use them in shifted mode, i.e., while depressing the shift.
You may use these numeric keys after typing a MULT CODE instead of the numeric keys
on the top row of the regular keyboard.

2.3. HEWLETT-PACKARD 2621A
The HP 2621 A offers an attractive character set and a large range of special functions
which give it the versatility necessary for use with much of the software currently available
at Columbia. For a summary of instructions about the HP 2621 A and HP2621 National
terminals. please see Appendix III, p. 76
(
Photograph 2-7:
Hewlett-Packard 2621 A
PLEASE NOTE
The HP 2621 A and the HP 2621 AlP National terminals are physically identical, but they
have slightly different settings.
Still. almost all of the information listed in this section
applies to the HP National as well. and thus is not repeated in that section. Currently. most
of the HP National terminals are located in the Carman terminal room. although this may
change.
The easiest way to determine which terminal you are using is to enter Configuration Mode
(see beiow section 2.3.3 p. 19) and examine the lower mode line. If LANGUAGE instead of
EX I T appears in the left most setting of the lower mode line it is a National terminal. The
mode lines are the white blocks with dark lettering which appear at the top and bottom of
the screen. Check p. 20 to see the mode line for the HP 2621A Also, check the Straps
parameter on the upper mode line. If it does not appear exactly as specified on p. 20,
i.e.. the National has an "a" in the field on the upper mode line, see below. 2.4. p. 25.

2.3.3. SETTING UP THE TERMINAL
2.3.3.1. FUNCTION KEY GROUP
The Function Key Group consists of eight Function Keys located across the top of the
keyboard (as illustrated opposite), and the Labels Key (the only blank key). located to the
right above the carriage return. These keys are used in a shifted mode, i.e., while holding
down the shift key, to configure the terminal for a given computer system. When the
keys are used without the shift key, they control cursor and scrolling functions. When
using these keys to configure your terminal. the computer has no knowledge that the
cursor has been moved. You cannot use these keys to position the cursor when using an
editor, e.g., EMACS.
After the terminal is turned on, eight labels--the Primary Labels--will appear along the
bottom of the screen. Each label corresponds to one of the eight function keys located
along the top of the keyboard.
There are six different sets of labels that may appear, depending upon what mode the
terminal is in. For the HP 2621A however, we will discuss only two sets, the Primary
Labels and the Configuration Mode Labels.
Note: When depressed, the Labels key calls back the primary labels, no matter what mode
you are in.
2,3.3.2, EXECUTING TERMINAL FUNCTIONS
Each of the labels along the bottom of the screen names a terminal function that you may
execute to achieve a desired effect.
There is a one-to-one correspondence between these labels and the function keys larrows)
on the top of the keyboard. The functions are executed by pressing the corresponding
function key while holding down the shift key.
When the terminal is turned on, the Primary Labels are initially displayed. In order to set
the values of various configuration parameters. you must put the terminal into
Configuration Mode.
NOTE: It is impossible to enter Configuration Mode unless the Primary Labels are currently
displayed. At any time you may recall the Primary Labels by pressing the Labels key, the
blank key on the right.
a
To enter Configuration Mode. hold down the shift key while pressing the
key.
Parameter labels and values will appear along the top of the screen. and the bottom labels
will change to the Configuration Mode labels.
The labels for the upper mode line are
displayed as follows for the DEC-20:

The SuperBrain is a Z80-based 8-bit microcomputer manufactured by Intertec Data
Systems Corp. It is equipped with two double-density 5-1/4 inch "minifloppy" disk drives
with a capacity of approximately 160K characters each. Up to 64 files can be stored on
a single floppy.
The SuperBrain runs the Intertec Data Systems version of the CP 1M
operating system.
The primary purpose of the SuperBrain is as a facility for copying files from either the
DEC-20 or IBM 4341 to floppy disks. It can only be used as a terminal if no other users
wish to copy files. See below section 2.5.1 for information on how to copy files. and
section 2.5.2 for further policy on usage. Information on how to use the micro as an
ASCII terminal is also presented below. Currently there is one SuperBrain terminal available
in Room 272A Mudd.

2.5.1. DOCUMENTATION FOR FILE TRANSFER
KERMIT is the program used for copying files to and from the DEC-20 or IBM computers.
The Kermit Technical Note for the IBM 4341 is available free of charge. For the DEC-20,
the Kermit Manual is available for purchase, but an excerpt of the Manual is also available
free of charge in the Reference Room in the SSIO area, room 115A.
2.5.2. USAGE POLICY AND SCHEDULING
The primary purpose of the SuperBrain is for file transfer to and from floppy disk.
Anyone using them for other purposes. i.e., as a terminal, must yield to users who need to
transfer files. Signup sheets are provided for scheduling of 20-minute slots. The length. of
the slot may be adjusted depending on requirements and demand. During periods of heavy
usage, t(he end of the semester), CUCCA reserves the right to limit use of the micro for
floppy access only.
2.5.3. OPERATING THE SUPERBRAIN
2.5.3.1. TURNING ON THE TERMINAL
1
To turn on the SuperBrain, flip up the toggle switch located on the back right-hand side.
This is known as a cold start. On a cold start the micro is automatically "booted", i.e. the
operating system is loaded into memory from the System floppy and started. After the
appropriate disks are loaded, (see below section 2.5.5), the following message will appear:
64K SUPERBRAIN DOS VER 3.1 FOR CP/M 2.2
A>
The "A>" is the micro's prompt. which signifies it is ready to accept input.
2.5.3.2. INTERRUPTING THE PROGRAM
There are two red keys located at the bottom corners of the main keypad. If these two
keys are depressed at the same time a warm start takes place; this means that whatever
program may be running is interrupted. the operating system is reinitialized, and you are put
back at CP/M command level. This is preferable to shutting off the terminal.

2.5.4. USING THE SUPERBRAIN AS AN ASCII TERMINAL
(
The SuperBrain emulates a VT52 terminal. Start up the micro with the system disk mounted
in the A drive. The B drive should be empty.
2.5.5. USING FLOPPY DISKS WITH THE SUPERBRAIN
The SuperBrain uses a pair of 5-1/4 inch single-sided, double density, soft-sectored
floppies, A (left) and B (right).
The System floppy disk should be mounted in Drive A, and should not normally be
removed. The System Floppy is available from the consultant when you leave your ID card.
The system disk contains the CP/M operating system and utilities, and the SuperBrain
version of Kermit, Kermit-80.
Drive B is available for user floppies. It is the vertical opening on the right. To insert a
disk in Drive B, open the drive by applying a very slight outward pressure on the small flat
door located in the center of the opening. Insert the disk with the label facing right, away
from the screen, notched edge up. Make sure the disk is all the way in by applying a
gentle' pressure on the rear edge of the disk. Once you are certain that the disk is fully
inserted, you may close the disk drive door by applying a slight pressure on the door,
pulling it back in the direction from which it was originally opened. Once the micro has
been started, you may give it commands.
(
When you are finished using the SuperBrain, remove the disks and turn it off. Turning of
the terminal with the disks still in place can cause damage.
2.5.5.1. DEC-20
Then run Kermit and login on the DEC-20 as follows. You type what is in italics. All text
starting with a "!" to the end of the line is a comment, and everything else represents

2.5.6. NOTES ON FLOPPY DISKS
Floppy disks (flexible disks. diskettes!. provide economical "removable media", i.e.. a cheap
way to store files offline such that they can be restored at a later time. Floppies consist
of a flexible platter mounted permanently inside a square cardboard jacket. The platter
turns inside the jacket. The machine's read-write head actually comes in contact with the
surface of the platter through a slot in the jacket. The rubbing of the platter against the
inside of the jacket and the read-write head can cause the the floppy to wear out after
prolonged or repeated use.
,
The jacket, in turn. is often kept in a paper envelope. The floppy is taken out of the
paper envelope and inserted in the drive with its jacket on. Floppies should never be
removed from their cardboard jackets. The shiny surface of the disk should never be
touched; always handle disks by their jackets. Disks shouid be stored in a box or solid
container. Never have the disks in their drives while the power is being turned on or off.
Do not bend the disk, or allow liquids or moisture to come in contact with the disk. Do
not place disk where they might be subject to magnetic fields, temperature extremes. dust,
or other contaminants. Finally. to not write on the jacket with a ball point pen.

Diablo 1620 Hyterm Printer
3.2. DIABLO 1620 HYTERM PRINTER
The Diablo 1620 terminal is a letter-quality printer which is used to print final copies of
essays, dissertations, etc. The quality of Diablo output is comparable to that of an electric
typewriter. Unlike most hardcopy terminals at CUCCA, the Diablo has been modified to run
at 1200 as well as 300 baud. The higher speed will expedite your work. To use this
terminal you must purchase a print wheel and ribbon available in the User Services Office,
Room 115, Computer Center (see below section 3.2.2). The Diablo terminal is located in
Room 272A Engineering Terrace.
3.2,1. USAGE POLICY AND SCHEDULING
The Diablo should not be used in lieu of a crt terminal but expressly

3.2.3. PAPER
CUCCA supplies scrap output paper, the standard continuous-form, pin-feed type in size
11 x 14 inches for login and logout procedures. All other paper must be supplied by the
user. Do not print directly on the platen; always print on paper.
3.2.4. AN IMPORTANT WARNING ABOUT DIABLO USAGE
The front cover plate has been removed in order to facilitate usage with several
computers. Warning messages are printed inside the terminal chassis. Please keep your
fingers, pens, etc. out of this area. The Diablo print head can move very quickly: if a
glitch character is encountered during transmission or receiving, if a system goes down, or
there is difficulty in attaching to a PACX line during the login procedure, the print head

3.2.5. BEFORE TURNING ON THE TERMINAL
Print Wheel and Ribbon Installation
To prepare the terminal for operation, first install the print wheel and ribbon cartridge,
These two operations must be done with the terminal power off (power light will be
off). NEVER attempt to install these Items when the power switch is ON,
All CUCCA consultants have been instructed in the proper use of the Diablo, Please ask
the consultant how to install the ribbon and wheel as well as how to handle the feeding
and allgrment of paper,
3.2.6, SETTING UP THE TERMINAL
There are three control panels on the Diablo, all of which should be checked before use,
3.2,6.1. INSIDE CONTROL PANEL
Note: These switches should be set with the terminal off,
Because of poor design, these switches are located within the housing of the terminal.
The cover plate has not been installed so that you may have access to these switches, All

3.2.7. CHANGING THE BAUD RATE
CUCCA has installed a special switch to enable you to use the Diablo at 1200 instead of
300 baud.
NOTE: Please be aware however, that the baud rate switch on the inside control panel
must be set initially to 30 for either system. The Diablo terminal may only be used reliably
at 1200 baud in conjunction with specifically designed programs. The Diablo program on
the DEC-20 is the only such program supplied by CUCCA. If you are experiencing
problems at 1200 baud. it is advisable to switch back to 300 baUd. DEC-20 users must
reset the speed of the terminal before using this switch.
The 1200 baud toggle switch is located under the keyboard on the left side of the
terminal. It is clearly marked for both speeds; DOWN for 300 baud; UP for 1200 baud.
3.2.8. TURNING ON THE TERMINAL
Only after setting the above switches and installing the print wheel and ribbon should the
terminal be turned on. The ON/OFF switch is the red rocker switch on the upper right hand
side of the terminal. Press it to the ON position.
3.2.8.1. RIGHT CONTROL PANEL--RED ROCKER SWITCHES
Several red rocker switches which provide more terminal control are located on the front
panel above the keyboard and to the right (see photograph opposite).
ERROR LAMP
A red light to indicate a problem with the software or
terminal.
RESET
To be depressed once the error lamp is lit to clear the
error condition and extinguish the light. For more information on error recovery see below, 3.2.11.
FORMFEED
Primarily for use with forms tractor which is not supplied
in Room 272A.
SET TOF
Used with Formfeed.
SCROLL
ON or OFF; leave off.
POWER
ON or OFF. The main power switch.
NOTE:
Because the front cover plate is not instalied. the white cover button located
directly in the middle of the terminal must be kept in the middle position (it will lock). If
this button is in the down or up positions. the terminal will not operate.

3.2.11. RESETTING THE TERMINAL AND ERROR RECOVERY
Reset Button
When the Error lamp is lit an alarm will sound. Press Reset to clear the condition. The
terminal settings, i.e., baud rate, duplex, etc.
remain the same. See below "Troubleshooting."
Clear Button
The red Clear button located on the right most side of the inside of the control panel
resets the terminal to the original settings. The print head is returned to the left It should
be used to clear a printer check error, or when the Reset button does not extinguish the
error light. Be aware however that the Clear button can clear all the software settings,
although it leaves the baud rate etc. as set. It should be used only if pressing the Reset
button does not clear the condition.
3.2.12. TROUBLE-SHOOTING
There could be a number of reasons why the error light is lit and the alarm sounds. At
times, it could be an erroneous error message which really does not require pressing the
Reset button, i.e" you could continue with the error lamp lit. However, to be safe you
should press Reset to extinguish the light. What follows is a brief summary of the most
common problems.
Problem
Cause/Remedy

The following problems will cause the Error lamp to light and the alarm to sound.
Ribbon Ended
When using a single-strike film ribbon, a series of colored
x's will appear to signal the end of the ribbon. You should
also check the window on the top of the ribbon. You can
only print a few more pages after seeing the x's. If
possible, replace the ribbon when the Diablo stops by
pressing LOCAL and removing the cartridge. If, unfortunately, the ribbon reaches the end in the middle of a
program, the Error Lamp will light and the alarm will sound.
Put the terminal in LOCAL, replace the ribbon and press
Reset, and your program should continue exactly where it
left off, so be sure to position your paper correctly.

CHAPTER 4
GRAPHICS TERMINALS
4.1. HEWLETT-PACKARD 2623A
The HP 2623A graphics terminal physically resembles one of the many HP 2621 A and
National terminals found at campus terminal sites. However. the HP 2623A is a graphics
terminal. It contains both an alphanumeric and a graphics display memory. The 2623A has a
built-in heat copier. which is capable of copying both the alphanumeric and the graphics
memory. The resolution of the graphics memory is 512 pixels across by 390 pixels up
and down the screen. in graphics mode. characters can be plotted in one of 8 different
sizes and at various slants. although there is only one hardware font available.
A certain level of competence is assumed for those using this and other graphics terminals.
Thus. we will cover only the most basic configuration information. Users should consult the
HP manual available in room 272A Mudd.
The HeWlett-Packard graphics terminals and plotters were donated to CUCCA by an
alumnus employed by Hewlett-Packard.

(
The HP 2623A user manual is available in the consultant's office in 272A Mudd. The HP
Graphics Plotter Operating and Programming manual is also available. The consultant can
assist you in the operation of the terminals.
4.1.2. A SPECIAL NOTE ON BAUD RATES
The HP 2623A can be used at 4800 baud for the DEC and 1800 for the IBM. However,
when used in conjunction with the pen plotter (see below 4.2), it must be set to 1200
baud for both systems.
4.1.3. TURNING ON THE TERMINAL
Like the other HP terminals, the ONIOFF switch is a wide black rocker switch on the back
right side of the terminal. Push it to the right to turn on the terminal.

Baud Rate
Usually, the terminal should be left at 1200 baud, which is
good for both the DEC and IBM systems. This is also the
maximum speed at which the plotter runs, and the two
must be synchronized. If you are not using the plotter, you
may set the baud rate to 4800 for the DEC and 1800 for
the IBM by positioning the cursor under the values and
pressing the F2 and F3 keys.

Rolled paper is provided in the plotter room. You may also purchase special paper in
Room 115. Gridless paper in sizes 8 1/2 x 11 and 11 x 15 1/2 is also available.
4.2.3. TURNING ON THE PLOTTER
The power switch is located underneath the front panel.
Push it in to turn on the plotter.
4.2.4. SETTING UP THE TERMINAL
The plotter can be in one of three basic modes: 2
1. Plotter is powered off.
An internal relay within the plotter connects the host
computer directly to the terminal.
The plotter never sees incoming or
outgoing data.
The host computer may operate at any baud rate that the
terminal and modem allow. This is not the case when the plotter is powered
on.
2. Plotter is powered on but not in plot mode. The plotter, when powered on,
passes data between the host computer and the terminal in the same way as
when the plotter is turned off, with two exceptions: (1) Since the plotter is
now powered up, it is actually interpreting the incoming data from the host
computer.
Therefore, the baud rate setting in the back of the plotter is
significant. This setting should be left at 1200 baud all the time, as should
the terminal and the host computer, to avoid confusion. (2) Since the plotter
is interpreting data when it is powered on, it can at any time intercept a
"plotter on" instruction from the host computer, at which point the plotter is
in mode 3 below.
3. Plotter is powered on and in plot mode.
At this point, the plotter will
intercept and interpret all incoming data from the host computer as plot data
up to the next "plotter off" command. The only thing seen at the terminal at
the time a "plotter on" instruction is sent is the "plotter on" instruction itself.
All other data following the "plotter on" instruction is intercepted by the
plotter and is not passed to the terminal until a "plotter off" instruction is
sent.

Upper Right
Move plotter arm to current upper right corner of plotting
area. If the Enter key is pressed prior to pressing this key,
the plotter sets the current arm position to be the new
upper right corner of the plotting area.
Lower Left
Move plotter arm to cu~rent lower left corner of plotting
area. If the Enter key is pressed prior to pressing this key,
the plotter sets the current arm position to be the new
lower left corner of the plotting area.
Enter
Enables alternate functions for some keys. When the Enter
key is pressed, the light in the center should start flashing
and continue to do so until another key is pressed which
executes the alternate function.
Pen position controls
The four buttons grouped around a larger button marked
"fast" are for manually positioning the plotter arm. Pressing
one of the buttons with the arrows on them moves the
plotter arm in that direction at the rate of 4.8 mm/sec.
Holding two adjacent direction buttons will move the arm in
a 45 degree angle between the directions specified by the
arrows. Pressing the "fast" button in conjunction with any
of the direction buttons causes the plotter arm to move in
the specified direction at a rate of 93.2 mm/sec. If the
plotter is in LOCAL mode and the Enter key is pressed
prior to pressing one of the direction keys, a rotation angle
is stored in the plotter causing subsequent relative plots to
be referenced in the direction of the arrow.
Pen Up
Raise pen arm off of the paper.
Pen Down
Lower pen arm on to paper.
Stby
Standby mode.
When this button is pressed, the light in
the center of the button comes on, the plotter buffer is
cleared of all unexecuted instructions, and the plotter
passes all data between the host computer and the terminal
unaltered.
The computer no longer has program control
over the plotter.
Local
Local mode. When this button is pressed, the plotter is
"listening" solely to the terminal. The light in the center of
the button comes on and any instructions currently in the
plotter buffer continue to be executed until the buffer is
empty. The host computer is disconnected from both the
plotter and the terminal. The plotter interprets instructions
coming from the terminal keyboard directly. If this button
is pressed repeatedly, the plotter goes alternately into and
out of "plotter on" mode.
This is indicated by the light
flashing when in "plotter on" mode. Graphics instructions
from the terminal are interpreted by the plotter only when
in "plotter on" mode (i.e" when the light is flashing).

When this button is pressed, the
plotter is "listening" to the host computer. The light in the
center of the button comes on and if the button is pressed
repeatedly, the plotter alternates between "plotter on" mode
and "plotter off" mode, as indicated by the light flashing
when in "plotter on" mode.
Any graphics instructions
currently in the plotter buffer continue to execute uninterrupted.
Pen select buttons
The four buttons marked with the digits 1 through 4 are
the pen select buttons.
Pressing one of these buttons
causes the plotter arm to pick up the corresponding pen,
returning any pen it already had to its stall. Pressing the
Enter key prior to pressing one of these keys has the
effect of returning the pen to that stall if the stall is
empty, and not picking up another pen.

The Tektronix 4631 hardcopy unit is used in conjunction with the Tektronix 4013 graphic
display terminal discussed above, Essentially, this terminal takes a photograph, or raster
scan, after the image is generated and displayed on the crt screen,
The ON/OFF switch is clearly marked on the front of the terminal, as are all other controls.
Turn on the unit a few minutes before use. Display your graphic on the crt then push the
Make Copy switch on the right side of the 4013. Your print will eject automatically from
the unit in a few seconds. Adjust the darknessllightness dial on the front of the terminal as
needed.

TERMINAL REPAIR AND INSTALLATION PROCEDURES
(
5.1. TERMINAL PROBLEMS
5.1.1. REPORTING TO SYSTEMS ASSURANCE
Hardware problems with CUCCA installed terminals and other teleprocessing equipment
should be reported to the Systems Assurance Group, 280-3100, or to the consultants in
SSIO, 280-3631, or in 272A Mudd, 280-3185. Each terminal has a two-digit identification number printed on red tape on the top of the terminal casing. Please tell Systems
Assurance the identification number as well as the location' of the terminal. Don't attempt
to repair CUCCA terminals yourself.
PACX problems should also be reported to 280-3100.
are planning to install teleprocessing equipment.
Contact Systems Assurance if you
5.2. PURCHASING A TERMINAL
It is strongly recommended that you consult with CUCCA before purchasing hardware which
is intended for use with any of the University's computer systems.
Requests for
information concerning types, performance, features of terminals, and possible discounts
should be directed to the Manager of User Services, Columbia University Computer Center,
612 W. 115th Street, New York, New York 10025, 280-3259.
Selecting the proper
terminal is especially important if you are considering using both the IBM 4341 and
DECSYSTEM-20 in conjunction with PACX.

Glossary and Abbreviations
71
GLOSSARY AND ABBREVIATIONS
ASCII
Most standard computer terminals are capable of transmitting 128 different characters that can be recognized by
the computer at the other end of the wire.
These
character codes make up what is known as the ASCII
(American Standard Code for Information Interchange) character set.
Baud Rate
A baud is a unit of signaling speed and refers to the
number of times the state of a line changes per second.
Simply, it is the speed of transmission to which the terminal
is set, e.g. 300 baud, 1200 baud, 1800 baud, or 4800
baud.
Baud is the shortened form of the name J. M.
E. Baudot, who designed a code for the French telegraph
system in 1877. The baud rate is generally 10 times the
characters per second (300b = approx. 30cps).
Cursor
The cursor is a special symbol--usually a blinking or
constant block of light, or an underscore, that signifies that
the terminal is on and charts your position on the screen.
It is roughly the equivalent of a print head on a printing
terminal.
Duplex
A full duplex terminal line is capable of transmitting data
in both directions simultaneously; a half duplex line can
transmit in either direction, but only in one direction at a
time. The duplex switch will normally determine whether or
not the terminal displays characters as they are typed,
regardless of the type of line being used to transmit those
characters to the computer.
Handshake
Handshaking, is the exchange of predetermined sequences
of control signals or control characters between two
systems to establish a connection, and lor control the flow
of data. A common handshake is XON/XOFF.
Local
Not connected to the computer; using the terminal in local
mode.
To use the computer you must be "online" or in
Remote mode. See below Remote.
Logging In
Log in or logging on--also signing on--to the computer. It
means identifying yourself to the system as a specific user.
You log in to the system by typing in your 10 name and
password. Each system differs in this procedure.
You
cannot use the computer until you log in.

Logging Out
Glossary and Abbreviations
Log out or signing off, the opposite of logging in, means
that you have finished your work on the system and want
to terminate your connection to the computer.
Parity
Since no transmission medium is totally reliable, it is important in some applications for computers and terminals to
notice when information is garbled during transmission.
Parity checking consists of sending one extra bit with each
character code transmitted. The extra bit contains information that can then be used for consistency checking with
the rest of the code.
Remote
Also referred to as ONLINE or LINE. You must be in
Remote mode to use the computer. The opposite of Local
or LaC.
CR
Carriage return often written as <cr> or (cr).
The key
iocated on the right side of the keyboard. Usually marked
(
Return.
LC
Lower case.
LF
Line Feed. Moves the cursor to the next line. Also as AUTO
LF for automatic line feed. Also CR/LF, carriage returnlline
feed.
LaC
Local. Not connected to the computer.
REM
Remote or connected to the computer.
TTY
Abbreviation for terminal, derived from teletype.
UC
Upper case.
