3)

1721 or 1722 Paper Tape Reader (Optional)

4)

1723 or 1724 Paper Tape Punch (Optional)

5)

1729 Card Reader (Optional)

The common synchronizer provides the interface logic between the computer A and Q
registers and the four peripheral devices.
controller.

Each peripheral device contains its own

The station codes assigned to the common synchronizer and peripheral

devices are as follows:
1)

Station 0 - Common Synchronizer

2)

Station 1 - Teletypewriter

3)

Station 2 - Paper Tape Reader

4)

Station 4 - Paper Tape Punch

CIRCUIT DESCRIPTION
This part of the manual contains operational descriptions of the teletypewriter, paper
tape reader, paper tape punch, and card reader.

These descriptions are intended as

an aid to the understanding of the logic diagrams contained in Part 1.

PROGRAM PROTECT
The program protect feature of the 1700 Computer System applies to the paper tape
reader, the paper tape punch, and the card reader of the low speed synchronizer.
Bit 17 of the Director Function code is designated as the protect bit.

If the PROGRAM

PROTECT switch is on, and the controllers for the paper tape reader, punch, and the
card reader are on, only those functions from the computer which have a protect bit of
"1" will be accepted by the respective controller.

All other instructions will be

If the respective controller PROGRAM PROTECT

switch is off, all instructions from the computer will be accepted and replied to.

1711-A/B/ 1712-A/ 1713-A/B TELETYPEWRITER
INTRODUCTION
The CONTROL DATA 1711-A/B Teletypewriter consists of a model KSR (keyboard sendreceive) teletypewriter and its associated controller.

The KSR teletypewriter is a basic

typewriter consisting of two units, a keyboard and a printer.

It provides for transmitting

messages by manual operation of the keyboard, and for receiving and printing messages
on paper.
The CONTROL DATA 1712-A Teletypewriter consists of a model ASR (automatic sendreceive) teletypewriter and its associated controller.

The model ASR teletypewriter is

. the same as the model KSR except that, in addition, it contains a paper tape punch and
a paper tape reader.

It provides for transmitting messages either by manual operation

of the keyboard or by reading punched tape.

It provides facilities for recording messages

by punching them on paper tape and/ or printing them on paper.

2-1

Information can be

Rev. W

prepunched into tape and the tape can be used to read this information into the system.
Also, messages coded in other than ASCII (American Standards Code for Information
Interchange) code can be transferred from tape to computer or computer to tape.

Inter-

connection of the various units of the ASR is accomplished via a 5-position rotary switch
located on the typewriter.
The CONTROL DATA 1713-A/B Teletypewriter consists of a model ASR teletypewriter
with its associated controller.

The 1713-A model is the 60Hz version and the 1713-B

model is the 50 Hz version. '!'hese are the same as the model 1712 ASR Teletypewriter
with these execeptions:
1) The 5-position rotary switch is replaced by an Electrical Relay Chassis with

relays contr0lling the five teletype operational modes.
2) It provides facilities for the programmed selection of teletype operational modes
in addition to the manually selected modes.
TELETYPEWRITER SYSTEMS
There are two communication systems used with teletypewriter stations and these are
termed the full-duplex system and the half-duplex system.

Full-Duplex System
The full-duplex system (Figure 2-1) allows simultaneous, two-way communication
between two teletypewriter stations.

A current loop between the keyboard of one station

and the printer of the other station allows the bits, representing the character selected
at the keyboard, to be transferred serially to the printer in the other teletypewriter
station.

Half-Duplex System

1700 TELETYPEWRITER SYSTEM

The 1700 teletypewriter system (Figure 2- 3) uses a combination of the full-duplex and
the half-duplex systems.

The teletypewriter is connected with independent current loops

but the controller ties the two current loops together to make the system represent a
half-duplex system.

In this way, certain control advantages inherent in the full-duplex

system are obtained, while the disadvantage of not being able to observe what is being
typed from the keyboard is eliminated.
The transfer of data bits representing a character, between the teletypewriter and the
controller, is performed serially.

The 7 bits of data and 1 bit of parity are enclosed

within 3 bits of synchronization to form an 11- bit or unit code for each character or
function.

When no operation is in progress, the current loop between the teletypewriter

and the controller is in a Mark condition (20-milliamperes current flowing in the loop).
Refer to Figure 2-4.

The clutch in the teletypewriter engages and rotates a cam containing ten

Eight lobes are used for contacting code bars representing data bits (7 data and

1 even parity bit), one for the code bar representing a Start signal, and one for the code
bar representing a Stop signal (the Stop signal lobe is twice as long as the other lobes).
A timing chain is used in the controller to simulate the rotating cam in the teletypewriter.

This keeps the proper logic (Holding register, etc.) in the controller synchronized with
the teletypewriter.
With an open current loop, the first code bar contacted represents the Start signal.

A

logical "0" Start signal is sent to the controller, the printer current loop is opened, the
clock is started, and the controller and the teletypewriter are synchronized.

The second

If a lobe contacts

a code bar, a Mark (indicating a logical" 1" condition) is sent to the controller.

If a

lobe does not contact a code bar, a Space (represented by a logical "a") is sent to the
controller.

The tenth lobe contacts the code bar representing a Stop signal and initiates

a logical "l" Stop signal to the controller.

The teletypewriter clutch releases and the

cam stops in an off position, waiting for the next character to be selected on the keyboard.
As the Mark and Space signals are received by the controller, they are re-transmitted
to the printer.

The printer assembles the bits and types the character selected.

They

are simultaneously sampled and gated to the appropriate Holding register flip-flop
within the controller.

Each bit transferred, including the Start signal, requires 9. 09

milliseconds to transfer one character and Stop requires 100 milliseconds.

Data transfer

occurs in a similar manner when the model ASR teletypewriter paper tape reader is used
instead of the keyboard.

If the controller is Busy, the Select Read Mode signal is

not enabled to the Write Mode FF and the Reject FF sets.

A Reject signal is then sent to

the computer.
NOTE
Certain functions (Select Read Mode, Select Write Mode, and
Clear Controller) will be rejected if the controller is busy.
However, since it is possible to transmit several function commands from the computer A register simultaneously, it is possible that a function will be replied to even if the controller is
busy, i. e., end of operation interrupt request may be sent along
with one of the above functions. In this case, a Reply will be

returned from the controller. The legal function, in this case
the end of operation interrupt request, will be performed but the
function which would normally have been rejected will not be
performed. It is therefore necessary to determine the condition
of the controller either before or after issuing such a function.
This is done using a status check.

Either

of the two flip-flops are used depending upon whether the controller is in Read or Write
mode.

The Read Data FF is set in this case, since the controller is in Read mode.

When the Clock Control FF clears, there is a delay of about 10 milliseconds before a
lOa-nanosecond pulse clears the Mechanical Busy FF.

The interval from the end of

time 9 through time 11 provides time for internal movements in the teletypewriter to
cease prior to the controller going Not Busy and allowing a new operation to start.

(The

la-millisecond delay is adjusted so that the Mechanical Busy FF just fails to clear when
the teletypewriter is running at full speed, which is 10 characters per second.) For
slow-speed operation, this flip-flop should stay set for approximately 100 milliseconds.
The Data status (A03) signal is sent by the Data Read FF to the computer to indicate
that data is available at the controller.

(If the Data Interrupt FF had been previously

set by Function and Select Data Interrupt instructions, the Interrupt signal would also
be sent to the computer at this time.) When the computer issues a Read signal, the gate

A Lost Data status signal is sent to the

Setting the Break FF opens the current loop between the teletypewriter and

the controller for 180 milliseconds.

This is equivalent to sending two Null codes to the

teletypewriter which shuts off any transmission, stops the paper tape reader if it is
running, and locks the keyboard.

It will be necessary to press the BREAK REL (Break
!

Release) button on the keyboard to resume transmission in a Read operation.

However,

the computer program may initiate a Write operation to output data or initiate a new
function without the keyboard being released.

To do this, the valid data being held in the

Data register must be read out in order to drop the Data and Busy status before the

(See Note under Select Read Mode. )

WRITE
When the computer issues a Write signal and the data to be typed, the gate to the Write
Enable circuit is made if the Write operation has been previously selected and Data
status is present.

ignored by the teletypewriter) of data (one character) from the computer to the Holding

This sequence repeats until all 8 bits of data

have been transferred to the teletypewriter at time 9.

Time 10 has no effect on the

characters per second.

The Mechanical Busy FF will stay set for approximately 100

microseconds. )
When the next Write signal and data to be typed are received, after the Mechanical
Busy FF clears, the Write sequence repeats.

INTERRUPTS
If the MANUAL/INTERRUPT switch on the teletypewriter keyboard is pressed at any

time during an operation, the Manual Interrupt FF sets. Both the Interrupt status and
the Manual Interrupt status are sent to the computer.
Data interrupt may be selected before or during an operation, which causes the Data
Interrupt Enable FF to set.

An interrupt will occur if any of the following conditions

are present:
1)

If the Data Interrupt Enable FF is set uI>0n selection of Write mode,

2)

If Write mode is selected and the Data Interrupt Enable FF is not set, upon

setting the Data Interrupt Enable FF,
3)

If Write mode is selected and the controller is Busy, and the Data Interrupt

Enable FF is not set, upon going Not Busy, or
4)

If Read mode is selected and the Data Interrupt Enable FF is set, upon setting
the Data Read FF.

If the end of operation interrupt is selected before or during an operation, the End of

Operation Interrupt Enable FF sets. The Interrupt signal is sent to the computer 12
milliseconds after the timing chain clears at the end of the timing cycle if another Start
pulse from the teletypewriter has not been received by the controller.

The interrupt is

used to inform the computer that the controller may be changed from Read mode to Write
mode.

The interrupt is not normally used in Write mode because the termination of an

operation takes place when a Write signal is not issued by the computer.
If the interrupt on alarm is selected before or during an operation, the Alarm Interrupt
FFsets. The Interrupt signal is sent to the computer when the teletypewriter becomes
Not Ready, a Lost Data condition occurs, or an Out of Tape condition is present (1713 Teletypewriter only). The Alarm status is available to the computer whenever the teletypewriter
is in a Not Ready condition.

TELETYPEWRITER OPERATIONAL MODES
The following five functions are programmable through the 1713 Teletypewriter controller
only.

They select operational modes in the teletypewriter.

The modes are also

manually selectable by use of momentary pushbutton switches.

Five switches are pro-

vided, each switch corresponding to a teletypewriter operational mude.

The 1712

Teletypewriter provides for manual mode selection only, by a rotary switch.

These

modes are not used in the 1711 Teletypewriter.
NOTE
The logic diagrams are referred to by page
number, card location number, and card pin
number. For example, 25.1-C17-14 refers
to logic page 25.1, card location B17, and
pin 14. Page numbers in parentheses refer
to the 1704 Computer logic diagrams.
Selection of a teletypewriter mode (either by a function or manually) will result in
setting one of the corresponding mode FF's.

These five FF's are K, KT, T, TTS, and

TTR modes located on module Z33 25. 1-C1 7.

1721/1722 PAPER TAPE READER
INTRODUCTION
Four models of the CONTROL DATA 1721 Paper Tape Reader and two models of the
CONTROL DATA 1722 Paper Tape Reader are available for use with the 1700 Computer
System.

Each of the models contains its own controller and a CONTROL DATA 350 or

370 Paper Tape Reader.

The 350 reader reads 5-, 7-, or 8-level tape at a rate of 350

characters per second; the 370 reader reads 5-, 7-, or 8-level tape at a rate of 400
characters per second.

The following indicates the contents of the various 1721 and

1722 Paper Tape Reader models:

The paper tape reader must be loaded with tape before operation can begin.

Refer to the

applicable paper tape reader reference manual listed in Part 3 for loading instructions.
Press the READER POWER switch.

Press the READY /MASTER CLEAR switch on the

reader to clear the controller for operation.

READ
When the tape reader is Ready, the controller provides Ready and Power On status
signals to the computer. To start the Read operation, the computer issues a Director
Function code (with the start bit 05 = "l ") which sets the Start FF. If the Data Ready

and Lost Data FFs are clear (no data in the Data register), the Clutch FF sets.

The

Clutch FF causes the clutch in the reader to engage and start moving the tape.
Setting the Clutch FF initiates a 40-millisecond delay.

If a change of state in the feed

hole is not sensed before the delay times out, the tape is not moving and the Paper
Motion Failure FF sets.

This provides a Not Ready status and an Alarm status to the

computer and enables the alarm interrupt.
In normal operation, a feed hole will be sensed before the 40-millisecond delay times

DATA INTERRUPT
When the data interrupt function is selected, the tape reader continues reading the tape
until a paper motion failure occurs (end of tape or a torn tape), a Lost Data condition
occurs, or until the interrupt function is removed.

The Lost Data condition occurs

when the last frame of data read was not transferred from the Data register of the
controller to the computer (Data Ready FF is still set) by the time the next feed hole
appeared.

This feed hole provides a signal which sets the Feed 1 FF.

1723/1724 PAPER TAPE PUNCH
INTRODUCTION
The CONTROL DATA 1723-A/B Paper Tape Punch consists of a controller and a
National Cash Register (NCR) EM-B1 Paper Tape Punch.

The CONTROL DATA

1724-A/B Paper Tape Punch consists of a controller, an NCR EM-B1 Paper Tape Punch,
and a NCR EM-B2 Tape Handler.

Each will punch 5-, 7-, or 8-level tape at speeds

from 0 to 120 characters per second.

LOADING
The tape must be loaded into the head of the paper tape punch before operation can begin.
Refer to the NCR EM-B2 Paper Tape Punch Manual, Pub. No. 60143600, for loading
instructions.

Press the POWER and READY /MASTER CLEAR switches on the punch.

The READY /MASTER CLEAR switch clears the controller for operation.

PUNCHING TAPE
When the paper tape punch is Ready, the controller provides a Ready signal and a Power
On status signal to the computer.

It also provides a Data status signal indicating that

the punch is not presently punching the tape.

To start the punching operation, the

computer issues a Director Function code (with start bit 05 = "l ") to the controller which
sets the Start FF.

The Start FF starts the motor in the punch and initiates a Busy signal

to the computer indicating that the controller is Busy.

The punch motor turns a timing

disc that generates Set and Clear Punch pulses, and Set and Clear Feed pulses to the
controller (Figure 2-5).

The Director Function code initiates a Reply signal to the

computer causing the start bit of the Director Function code to drop.

After the Start FF

sets, there is an 800-millisecond delay which permits the punch motor to reach operating
speed before pulses from the paper tape punch are accepted by the controller.
When the computer issues a Write signal with the data to be punched, the Reply FF sets.

signal is rejected until the punch has processed the data presently in the Holding register. )
After data is placed in the Holding register, the Set Punch pulse and the output of the set
Punch 1 FF sets the Punch 2 FF.

This provides a Feed Hole signal to the punch and

gates the data from the Holding register to the punch.

of data bits.

The Data status signal is returned to the computer indicating that the punch

is not punching and can receive additional data bits.

The Clear Feed pulse from the

punch clears the Feed FF and the punch stops moving tape.

On receipt of the next Write

signal and additional data bits from the computer, the punch cycle repeats.

INTERRUPTS
Two interrupts may be used during operation of the paper tape punch.

These are data

Either interrupt may be selected with or after

the Start instruction is issued.
When the data interrupt request is selected, bit A02 is a "1".

when power to the punch is off.
Interrupt conditions may be sensed by a computer status check whether the interrupts
are selected or not.

STOP
Upon completion of punching a frame of data, the punch remains ready to perform
another punch operation until the computer issues a Director Function code with stop
bit 06 equals "1".

The Stop signal clears the Start FF and turns off the punch motor.

Also, if there will be no punching within the next 60 seconds, the Stop signal should be
issued.

A RSE status is present 30 ms after

caused by an empty hopper, a feed
failure, or an operator error.

LOADING
The cards to be read should be placed face down in the card reader hopper with row
nine at the rear of the stack.

Pressing the Register (REG) switch on the card reader

will move one card from the hopper to the read station.

Arrival of the card will

cause the card reader to generate two signals to the controller.
1.

One signal indicates that the read station is not empty (RSE) and that this
signal will remain until the card leaves the read station.

2.

The other signal is a Field pulse of 3.5 ms duration.

The Field pulse and

the RSE signal set the Field 1 and Stop FFs.
The Field 1 FF (39-A03) sets on the leading edge of the Field pulse since the Field
2 FF (39-A03-test point 5) is clear.

With the Field 1 FF set, the RSE signal pre-

sent, and the Motion FF (41-B02) clear, the Stop FF (43-B04) sets.

Setting the

Stop FF will provide a Not Busy status and enable sending a Stop pulse to the card
reader.

The Field 2 FF remains set.

The column 79 Clock pulse starts the

As the information is transferred to the computer,

the reply clears the Data FF (41-B02); then the cleared Permit Read FF provides a

2-31

Rev R

Condition 1
When the MAN / A UTa switch is placed in the MAN (Manual) position, the card reader
will not feed cards from the hopper.

This places a "1" at 43-B04-4. As the card

leaves the read station, column 82 places a "1" at 43-B04-2.

With inverter D clear,

AND gate G outputs a "0" sending a "1" Stop signal to the card reader.
Condition 2
With the RSE (43-C03-8), pressing the REG switch will allow one card to come into
the read station.

This places a "1" at 43-B04-6 setting both FFs (D :: "0").

This

disables AND gate G and causes AND gate E to output a "0", sending a Stop signal
to the card reader.
During normal operation, if the card leaving the read station is not the last card to
be read, another card should enter the read station within 30 ms. If not, AND
gate E will output a "0", causing the card reader to stop.
Condition 3
As a card leaves the read station, the pressure rollers are raised, causing a "1" to
appear at 43-B04-10.

Since Clock pulses are generated up to column 82, this

enables the AND gate at test point 5 to output a "0", sending a Stop pulse to the card
reader.
Condition 4
With the Field 1 FF set, the Field 2 FF clear, the Motion FF clear, and a card
entering the read station (RSE), the Stop FF (43-B04) sets, sending a Stop pulse to
the card reader.

This stops the card on column 1.

The card reader must receive

"0" signal progresses through

the chain of inverters causing a Reject signal (41-B03-1 = "1").

The computer sends a request for each column of information it receives off the
card. A request places a "1" at 41-B02-8. If station 6 is present (card reader
connected), inverter H outputs a "0" to 41-B03-4, starting a O. 5-ms timeout in the

Setting the Motion FF will also clear the Stop FF (43-B04) re-

moving the "1" at 39-B01-1.

A function will not be replied to and it will be rejected

The reader becomes Not Ready when the

CLOCK AND FIELD PHOTODIODE POSITION
Remove the program disk and position a card on any column between 1 and 80 by

The amount of backward rotation corresponds to the 1 millisecond that the

Clock and Field pulses need to go to a "1" before the escapement wheel (column position).
If adjustment is needed, perform the following procedure.
