This operating and service manual covers general
information, installation, programming, theory of opera·
tion, maintenance, and replaceable parts for the Hewlett·
Packard 12653A Line Printer Interface Kit (see figure 1-1).

GENERAL DESCRIPTION.
1-4.
The HP 12653A Line Printer Interface Kit pro·
vides the necessary equipment to enable using the
HP 2767 A Line Printer with an HP 2114, 2115, or 2116
Computer. The kit contains the following items:
a. The Device Command signal (called Data Strobe at
the line printer) indicates when data is available for transfer
to the line printer.
b. Output register bits 0 through 6 (called Data
signals 1 through 7 at the line printer) represent an ASCII
(American Standard Code for Information Interchange)
character for printout or one of the following control
words: line feed, form feed, or carriage return.
1·7.
The following infonnation is transferred from the
line printer, to the interface card:
a. 12653-60002 Line Printer Interface Card.
a. Input register bit 0 (called Demand Line signal at
the line printer) indicates the line printer busy status.
b. 12653-60001 Cable Assembly.
c. 12653-90002 Operating and Service Manual.
1-5.
The line printer interface kit uses a printed·circuit
card with integrated circuits (positive-true logic) to transfer
data and status information between the computer and the
line printer. The interface card contains two 16-bit registers;
one for output from the computer and one for input to the
computer. Seven data bits are transferred from the computer
through the output register to the line printer, and two status
bits are transferred from the line printer through the input
register to the computer. In addition to the two registers, the
interface card contains control and interrupt logic circuits
that permit programming of the 1/0 functions.
b. Input register bit 15 (called Ready signal at the line
printer) indicates the line printer ready status.
c. The Device Flag signal (called Demand Line signal at
the line printer) indicates when the line printer is uncondi·
tionally able to accept new data.
1-8.
IDENTIFICATION.
1·9.
Printed·circuit card revisions are identified by a
letter, a date code, and a division code stamped on the card
(e.g., A-1024·22). The letter code identifies the version of
2.115-6

the etched trace pattern on the unloaded card. The date
code (four middle digits) refers to the electrical characteristics of the loaded card. The division code (last two digits)
identifies the Hewlett-Packard division that manufactured
the card. If the date code stamped on the printed-circuit
card does not agree with the date code shown on the title
page of this manual, there are differences between your
card and the card described in this manual. These differences are described in manual supplements available at the
nearest HP Sales and Service Office.

PROGRAMMING.
2-15.
The following paragraphs provide information for
programming the line printer interface card and line printer.
This information consists of the line printer characteristics,
status and timing considerations, and a sample assembly
language program. Additional programming information is
available in the software manuals supplied with the
computer.
2-16.
a. The single line control word is programmed by an
octal 012 and causes the paper to advance one line. A
request for new data is initiated before the paper stops. If
the first input data for the next line is also a single line
control word, the request for new data is cancelled and the
printer advances paper to the next line. To avoid printing
on perforations, an Automatic Perforation Stepover signal
is initiated by the line printer. When a page boundary
(perforation) is sensed, the Automatic Perforation Stepover
signal causes the next single line control word to advance
the paper six lines, three above and three below the
perforation.
b. The top-of-form control word is programmed by an
octal 014 and causes the paper to advance to the top of the
next form. The paper automatically stops at the third line
following the next perforation. A request for new data is
initiated before the paper stops.
LINE PRINTER CHARACTERISTICS.
2-17.
The line printer prints up to 475 characters per
second depending upon the message length and pattern.
Each character requires 7-bits of data (ASCII code) and
when each twentieth character is loaded in the line printer
input buffers, a print cycle is automatically initiated. Print
cycles require from 0.57 to 34.2 milliseconds to complete
depending on the distance around the print drum to the last
printed character. During the print cycle, characters cannot
be loaded into the input buffers.
2-18.
Characters are printed in 1 to 4 fields across the
print drum with up to 20 characters being printed in each
field and a maximum of 80 characters per line. Printing
fewer characters per line increases the number of lines
printed per minute and decreases the average number of
characters printed per second due to the increased time
used to feed paper. The minimum printing rates using the
four fields are shown in table 2-2.
2-19.
The line printer accepts ASCII coded data over
seven data lines from the interface card. This data is
converted into 64 printed characters and 3 format control
words by the line printer input buffers. Printed characters
include the 36 standard alphanumeric characters, 27
punctuation marks, and a space. The format control words
are: single line, top-of-form, and carriage return. Each of
these control words causes the printer to finish printing any
characters remaining in the input buffers and then to
perform the control word action as follows:
c. The carriage return control word is programmed by
an octal 015 and clears the control registers so that the next
character is printed at the left margin.
2-20.
STATUS SIGNALS.
2-21.
The line printer supplies two status signals that are
sent to the interface card. These signals appear as bits 0
and 15 of the input register. Conditions indicated by the
status bits are as follows:
BIT
CONDITION
o
Busy signal. Logic 0 indicates that the
line printer is unconditionally able to
accept new data (on line and ready).
Logic 1 indicates that the line printer is
storing a character, a print cycle is in
progress, or the printer is not on-line and
ready.
15
Ready signal. Logic 0 indicates that the
line printer is ready to be put on-line and
that the following five conditions are
true: (1) line printer power is on,
(2) paper is loaded, (3) drum gate is
closed, (4) motor is running up to speed,
and (5) paper feed motor is not over
heated. Logic 1 indicates that a fault
condition exists in the line printer.

DEVICE FLAG SIGNAL. To initiate a Device
Flag signal the line printer must be in ready status, placed
in the on-line mode by the operator, and not busy processing a previous input. The line printer is in ready status
when the power is on, drum gate is closed, paper is loaded,
and no fault conditions exist. When the line printer is
ready, the ready status signal goes low and remains low.
The operator selects the on-line mode by setting a switch
on the line printer. With these two conditions met, the line
printer can receive and process inputs from the interface
card. Inputs from the interface card consist of characters
and control words (containing seven bits each) that are
transferred serially to the line printer. Each character or
control word received by the line printer is stored in the
input buffers. The input is then decoded and the control
word action performed. The line printer is busy when it is
transferring data to storage or performing one of the control
word operations. While the line printer is busy, the Device
Flag signal is high. The Device Flag signal is low only when
operations are complete and the line printer is not busy.
TIMING.
Note
In the following discussion, high refers to
the more positive signal and low refers to
the less positive signal.
2-23.
Line printer operation is synchronized through
Device Flag and Device Command signals. (These signals are
called Demand Line and Data Strobe, respectively, on the
line printer diagrams.) The Device Flag signal is initiated by
the line printer when it is able to accept an input from the
interface card. The Device Command signal is initiated on
the interface card by a programmed instruction. Device
Command signals are sent to the line printer to indicate
when interface card outputs are ready to be transferred to
the line printer. Figure 2-1 shows the interface card signal
timing.

Section II
2-25.
The Device Flag signal is used by the interface card
to indicate busy status, to acknowledge the transfer of data
to the line printer, and to indicate to the computer when
the line printer is ready to accept new data. To indicate
busy status, the Device Flag signal line is connected to the
input register Bit 0 FF. When the flip.flop output is a
logic 0, the line printer is not busy (figure 2-1). To
acknowledge data transfer, the Device Flag signal transition
from low·to·high is used to clear the Device Command FF.
The Device Flag signal goes from low·to.high when the line
printer receives and is processing new data. As soon as the
data processing is complete, the line printer is again not
busy and the Device Flag signal goes from high·to-low. This
transition from high-to-Iow causes the Flag FF to be set.
Setting the Flag FF indicates that the data processing is
complete and the line printer is ready to accept new data.
additional data until the transferred data is stored. When
the character or control word is . transferred to the line
printer, the line printer causes the Device Flag signal to go
high. During the low-to-high transition, the Device Flag
signal acknowledges the data transfer by causing the Device
Command signal to go low. The Device Command signal
remains low until the computer is again programmed to
transfer data.
2-26.
DEVICE COMMAND SIGNAL. The Device Command signal is initiated by programming a set control, clear
flag (STC,C) instruction with the line printer select code.
First, a character or control word is transferred from the
computer to the interface card output register by an OTA
or OTB instruction. Then, the set control portion of the
STC,C instruction initiates the Device Command signal. The
Device Command signal enables the transfer of data from
the interface card to the line printer. The clear flag portion
of the instruction causes the computer to hold any
2-28.
2-4
2-27.
The line printer accepts and stores 20 consecutive
characters and then automatically initiates a print cycle. A
print cycle is also initiated by any of the three control
words. When the line printer receives any control word, it
first prints the characters that are stored in the line printer
input buffers and then performs the control word function.
The control word functions are: single line paper advance,
top-of-form paper advance, and carriage return.
ASSEMBLY LANGUAGE PROGRAM.
2-29.
Table 2-3 provides an assembly language program
that indicates the operations and instructions required to
transfer data from the computer memory to the line printer
for print out. This program, when assembled on an object
tape, will perform a print out using the skip-if-flag-set (SFS)
method. The interrupt method is also availlible; however,
the program is more complex because of subroutine
requirements.

INTRODUCTION.
3·2.
This section contains a functional description and
a detailed circuit description of the line printer interface
card. Also included at the back of this section is an opera·
tional flow diagram (figure 3·2) of the interface card.
3·3.
FUNCTIONAL DESCRIPTION.
3·4.
The line printer interface card contains an output
register and the necessary control circuits to transfer data
from the computer to the line printer. The interface card
also contains an input register used to transfer status infor·
mation from the line printer to the computer. All functions
are performed under programmed instructions and result in
characters being printed by the line printer. Programmed
instructions initiate the control signals that are sent from
the computer to the interface card (figure 3·1). These
control signals enable the interface card output register so
that data is transferred from the computer to the register.
Control signals then initiate a Device Command signal that
is sent from the interface card to the line printer. When the
line printer is on·line and ready to receive data, it responds
to the Device Command signal by printing.
printing or one of three control words. As the character or
control word is received by the line printer, the line printer
stores or processes the data as required and then returns a
Device Flag signal to the interface card. The Device Flag
signal indicates when the line printer is ready to receive
more data.
On the interface card, the Device Flag signal
3·6.
initiates either a Skip Flag or Interrupt Request signal
depending on the method programmed for data transfer.
The initiated signal is then sent to the computer to start the
next data transfer. Data transfer continues as long as the
computer is programmed to transfer data to the line printer
and the line printer remains on-line and ready.
3·7.
Line printer status is indicated by two status
signals that are sent from the line printer to the interface
card input register. To read status indications, Control
signals are used to enable the input register and send the
information to the computer. The signals indicate the line
printer ready and busy status and both signals are false
when the line printer is ready, on-line, and not busy processing data.
3-8.
3·5.
Data is transferred from the computer to the inter·
face card and then to the line printer in 7·bit parallel
ASCII. Each data transfer represents one character for

used to establish operating conditions for the integrated
circuits. These jumper wires must be installed or removed as
shown in table 2-1. The jumper wire configuration is also
shown on the line printer interface card schematic diagram
and parts location view, figure 4-1. In this configuration,
some components are not used and are not described in the
following paragraphs. Circuits that are described are divided
into eight circuit groups as follows:

TURN-ON AND PRESET CIRCUIT.
3-11.
The tum-on and preset circuit establishes initial
conditions for the interface card logic circuits. At computer
power tum-on or when computer preset is enabled, the
computer sends true POPIO(B) and CRS signals to the
interface card. The true POPIO(B) signal is inverted to set
the Flag Buffer FF which then enables the Flag FF at the
next time T2. This inverted POPIO(B) signal is inverted
again to provide a true Latch signal to the output register.
Computer inputs to the output register are false during
tum-on and preset so that a true Latch signal clears the
register. The true CRS signal is inverted to clear both the
Control and Device Command FFs.
3-12.
SELECT CODE DETECTOR CIRCUIT.
3-13.
The select code detector circuit enables the line
printer interface card to accept and perform the instructions intended for the line printer. When the line printer is
addressed by programmed instructions, the SCM and SCL
signals are both true at the interface card. The lOG signal
goes true when any instruction is programmed for an 1/0
device. These three signals are combined and inverted, and
then inverted again and distributed to the programmed
instruction signal input gates. Therefore, all three signals
must be true before the interface card will accept a programmed instruction.
3-14.
FLAG CIRCUIT.
3-15.
The flag circuit provides initial conditions that
allow the computer to send data to the line printer by
either the interrupt or skip flag method. This circuit
contains the Flag and Flag Buffer FFs and the device flag
pulse shaping network. One condition that is required to
transfer data is that the Flag FF be set. The Flag FF is
always set at T2 (ENF signal true) of the following machine
cycle after the Flag Buffer FF is set. Setting the Flag
Buffer FF is done by any of three methods; during power
turn-on and preset by the POPIO(B) signal, by programming an STF instruction, and by the Operation
Complete signal from the device flag pulse shaping network.
The Flag and Flag Buffer FFs are both cleared by a CLF
3-2
instruction and the Flag Buffer FF can also be cleared by
an IAK signal from the computer.
3-16.
The line printer sends a Device Flag signal to a
pulse shaping network on the interface card. During the
time that the line printer is busy storing or printing data,
the Device Flag signal is held true. When the line printer is
ready, on-line, and not busy storing or printing data, the
Device Flag signal goes false and is held false until new data
is accepted. These changes in signal levels are used by the
pulse shaping network to develop Command Acknowledge
and Operation Complete signals as follows: When the
Device Flag signal is false (line printer not busy) the input
to gate U86C is false at pin 13 and true at pin 12. During
the transistion of the Device Flag signal from false to true,
pin 13 to gate U86C goes true and pin 12 remains true
providing a false output until capacitor C5 discharges. This
false output is the Command Acknowledge signal that is
used to clear the Device Command FF. The Operation
Complete signal is developed in the same manner except
that the output is inverted through gate U85B. This inversion provides a true Operation Complete signal when the
Device Flag signal goes from true to false. The true Operation Complete signal is used to set the Flag Buffer FF when
the line printer is ready to accept data.
3-17.
CONTROL CIRCUIT.
3-18.
The control circuit is enabled to signal the line
printer that data is available at the interface card output
register. This circuit contains the Control and Device
Command FFs. Both flip-flops are set by an STC instruction and cleared by a CRS signal or CLC instruction. The
Device Command FF is also cleared by a Command
Acknowledge signal from the device-flag pulse-shaping
network. (Refer to paragraph 3-16.) Normally, the
Control FF is set by the first STC instruction to the interface card and remains set until a CRS signal or CLC instruction is received. When set, the Control FF provides one
condition for enabling the interrupt circuit. When the
Device Command FF is set, the false clear-side output is
sent to gate U75A. This gate inverts the false signal and
sends a true Device Command signal to the line printer.
3-19.
INTERRUPT CIRCUIT.
3-20.
The interrupt circuit interrupts computer operation on a priority basis. During the interrupt, data is transferred from computer memory to the line printer. The
interrupt circuit contains the IRQ FF. Initial conditions are
established when the Flag and Control FFs are set and an
lEN signal is received to enable gate U46B. An lEN signal is
received when an STF instruction is programmed with
select code 00. The false output from gate U46B is sent to
gate U25A and inverted and sent to gate U35A. If gate
U25A also receives a true PRH signal, indicating that there
are no higher priority cards requesting an interrupt, the gate
output goes false, sending a PRL signal to all lower priority
cards. The PRL signal inhibits all lower priority cards from
interrupting line printer operation. Gate U35A also receives
a PRH signal, a signal from the set-side output of the Flag
Buffer FF, and an SIR (T5) signal. If all the inputs to gate
12653A
Section III
U35A are true, the output goes false and sets the IRQ FF.
Setting the IRQ FF provides FLG and IRQ output signals.
When the IRQ FF is first set, the true FLG and IRQ signals
are sent to the computer to initiate an interrupt phase
(phase 4) during the next machine cycle.
3·21.
During the interrupt phase, at time T2, the ENF
signal is true and the SIR (time T5) signal is false. The ENF
signal then clears the IRQ FF to allow any higher priority
cards to use the requested interrupt phase. If a higher
priority card does not use the requested interrupt phase,
the PRH signal remains true, as do the other inputs to gate
U35A, and the IRQ FF is set a second time at time T5 (SIR
goes true). When the IRQ FF is set the second time, the
true FLG and IRQ signals are used to decode the interrupt
address.
3-22.
The next machine cycle is then controlled by the
instruction located at the interrupt address in the computer
memory. During this machine cycle, the computer sends an
IAK signal to the interface card that clears the Flag Buffer
FF at time T1, and the ENF signal clears the IRQ FF at
time T2. Clearing the Flag Buffer FF prevents the IRQ FF
from being set again after the requested interrupt is
enabled. However, the Flag FF remains set to provide a
false PRL signal and inhibit lower priority cards from
interrupting until the requested interrupt is complete. To
clear the Flag FF and enable lower priority cards to interrupt, a CLF instruction must be programmed.
3-23.
SKIP FLAG CIRCUIT.
3-24.
The skip flag circuit is used to transfer data from
computer memory to the line printer using a non-interrupt
method. Before using the non-interrupt method, a CLF
instruction is usually issued to select code 00 to disable the
lEN signal and ensure that interrupt cannot occur. To
enable the skip flag circuit, an SFS or SFC instruction is
issued with the line printer select code. With the SFS
instruction, the Flag FF must be set to provide a true SKF
output signal to the computer. For the SFC instruction, the
Flag FF must be cleared to provide a true SKF output
signal. The true SKF signal tells the computer that the line
printer is ready to receive data. With this method of transferring data, the computer is programmed to wait in a
recycling loop before each data transfer until the SKF
signal is true.
3-25.
OUTPUT REGISTER.
3-26.
The output register provides a buffer between
computer memory and the line printer. Data to be trans-
ferred is first stored in the output register and then read by
the line printer. The output register contains 16 latching
flip-flops. However, only seven (bits 0 through 6) are used
for line printer data transfer. Latching flip-flops can change
states only if the latch input is true. Each signal input is
applied to boih the set- and clear-side input pins. When the
latch input is true, a true input signal causes the flip-flop to
set, and a false input signal causes the flip-flop to clear.
Input signals to the flip-flops are applied directly from the
computer on the lOBO lines and are applied to the lines by
an OT A or OTB instruction. The same instruction causes an
IOO signal to be applied to gate U45C. Gate U45C is
enabled if the OTA or OTB instruction was addressed with
the line printer select code and the IOO Delay FF is set. The
1O0 Delay FF inhibits gate U45C until computer time T4.
This allows time for the data on the lOBO lines to stabilize.
At time T4, gate U45C is enabled and its output inverted
by gate U85A. The resulting true IOO (delayed) signal is
applied to the output register latch inputs, and data on the
lOBO lines is loaded into the output register. Output gates
of the output register are continuously enabled through
gate U75B. To read data from the output register, the line
printer must receive a Device Command signal from the
interface card. Data sent to the line printer is in seven-bit
parallel ASCII code with each seven-bit word representing
one character for printing or one control word.

INPUT REGISTER.
3-28.
The input register provides a buffer for transferring status information from the line printer to the
com puter. Status information is always available at the
input register and can be read by the computer by an LIA
or LIB instruction. The input register contains 16 latching
flip-flops. However, only the Bit 0 and Bit 15 flip-flops are
used. The latch input to the Bit 0 FF is tied to +4.5V dc
through resistor R67, and the latch input to the Bit 15 FF
is tied to +4.5V dc through resistor R75. This keeps both
latch inputs at a true level so that true inputs will set the
flip-flops and false inputs will clear the flip-flops. Input to
the Bit 15 FF is provided from the line printer lleadY
output. The signal is false when the line printer is ready.
Input to the Bit 0 FF is provided from the line printer
Device Flag signal line. The Device Flag signal is false when
the line printer is on-line and not busy storing or printing
data. To prevent erroneous indications, the input pins to
the Bit 1 through Bit 14 FFs are tied to ground at the
interface card connector. Output gates of the input register
are enabled by an LIA or LIB instruction with the line
printer select code. This instruction develops an 101 signal
that is sent through gate U25B to enable the output gates.
