Duration of Test

In the print test portion, the program transfers
many useful print patterns to the control for out=
put on the printer. These patterns are designed to
offer visible checks of the printers mechanics.
The printer is mechanicallyadjusted prior to shipment.
However, if a discrepancy is noted, it will be nece.ssary to have a qualified techni'cian make the appropriate adjustments to the printer.

The LP15 diagnostic shall be allowed to run fifteen
minutes in the control test and through one pass
of the print test.

Operating Modes
The control has two modes of operation:
IOPS ASCII, and IMAGE ALPHA. All monitor
controlled data is stored in the format of a
header word and a text. The header word
consists of two consecutive locations containing the mode of output data flow. The
following locations, (the text), contain the
data in the form described by the header word.
· The text is terminated on the receipt of a
carriage ·return (CR), ALT MODE (ALTl, or a
character which requires the movement of paper
in the vertical direction: namely: VT, LF,
FF, DCl, DC2, DC3, DC4, and DLE.
The controller operatiny in the single line
mode will look for any of these characters to
end the line (print) and set the done flag.
In the multi-line mode, the same conditions
apply, however, the line counter is used to
end the cycle.

printer. After the control has received
twenty characters, and transferred them
to the printer, the printer will initiat
a print cycle which will print the
twenty characters. The demand line will
become true again, requesting twenty
more characters. A total of four of
these twenty character transfers will
be made terminating when the printer
receives the last twenty. It will then
print those twenty and space tho paper,
according to tho control character
issued.

The control, operating +n the software monitor
mode, requests two cons¢cutive data channel
breaks to retrieve the header word. It then
sets the appropriate mode flops and requests
the data. In the multi-line mode, bits 1 - 8
of the first header word are loaded into the
line c0unter. The ~ontroller handles the data
in either of the following modes:
6.3.1.l

!OPS ASCII Mode
In the !OPS ASCII mode, the characters
are extracted from memory by the data
channel 3-cycl~ output transfer. The
interface requests two consecutive data
breaks from the I/O and loads the first
18-bits of data into its data buffer
register bits ¢¢-17. The second data
break transfers another 18-bits into
the data buffer bits 18-34. Bit 17 is
unused in the second word. The control
will then sample the £irst character
to determine if it is a contcol character or printable character. If a
printable or illegal character is found,
it is shipped to the printer, and the
next character is shifted through the
data buffer, and the same oper.ation will
repeat itself until the buffer is empty
or a control character is encountered.
Once the five characters have been sent
on to the printer memory, the control
requests another pair of data breaks to
retrieve another five characters. This
operation takes place four times, (providing all characters are printable) .
Illegal characters cause the printer to
insert a space code. After five charact. rs
have boen transferred to tho printer,
two moro data breaks aro initiatod to
obtain five moro char actors. :"c:-ur of
those operations aro porformod until
twenty characters have boon sont to the

The transfer rate between the interface
and the line printer is 500KIIZ.

6 .. 3.l.2

This mode of operation differs from the
other in that only one character is
stored in an 18-bit word, (bits 11-171 •
The loading sequence is identical, but
two data breaks are required to load jus
two characters as opposed to five. The
control ships these characters to the
printer without a shift operation.
If the data buffer bits 11-17 contain
a printable character, the output gating
gates bits 11-17 to the printer, Por
the second character, the data buffer
bits 29-35 are scanned and if printable

the following character is printable, it
will go into the next column. Therefore,
if the character sequence is "A, (HT), B",
where "A" might go into column 7, the
"B" will go into column 9. However, if
the "A" was placed in column e, the "B"
would go into column 17. The interface
always sends at least one space. Aftor
the hori?.ontal tab operation, the
character transmission returns to the
no~·mal mode. With the 80 column 231,llJ
'
printer, an llT sent with a column count
equal to or greater than 72 constitutes
an error condition. When an error condition arises, the "ILL IIT" flag sets
and forces an error. Likewise, if a
241,llJ printer is l>oing used, an errc.r is
generated for a column count greater than
128.

a number of lines from 1 to 256 may be
printed in one operation. This is
accomplished by loading a line count
of 8 bits into the line counter. During
the first header word transfer, the soft
ware mbnitor may place a count in the
header word and issue the multi-line
IOT for processing. The lino counter
is decremented by one each time a
terminator is issued during a line of
print. The multi-line mode operation
is terminated when a control character
is encountered in the last lin~ of
print.

In the single line mode, only one line
may be printed. The operation is complete on receipt of the first control

In this mode, the operator need only
issue IOT 6S4l, no line count manipulation is required.

The control uses a CR code to terminate
one line of print. This is accomplished
by passin~ ~h~ CR onto the printer,

When operating in the multi-line mode,
the CR signals the control to zero the

the methods listed in the following sections:
6.3.2.1 through 6.3.2.7.

If operating in the single line mode,
the CR command will zero the column

DCH control
The DCH control affects the cycle
stealing operation of the intorface by
initially taking two consecutive data
breaks to load the header word and then
groups of two breaks to get five
characters each time into the data buffe
(IOPS ASCII\, and two characters each
time for I~GE. Using the three cycle
break feature of the PDP-15, and operati g
in the IOPS mode, the interface can
obtain five characters in two consecutive output transfers totalling 13 usec,
providing tho data break dolay is set
to the minimum.

The drivers will consist of open
collector type bus drivers with logic
assertion levels of ~ and+2.5' volts.

Likewise, for the 231~ 8~ column
printer, the ma;>c count is 80(lOl•
I

The column counter is used for calculating the line! over error, the horizontal tab, . and: illegal horizontal tab
operations. During the HT operation,
the three least' significant bits of the
printer are monitored for ccilculating
the tab stops . . The illegal horizontal
tab flag is set: when a user tries to
tab beyond 72, or 128 with the 8~ or
132 column printers respectively.

The receivers will merely buffer the
incoming signals.
6.3.3.12

The interface contains a unit which will
electrically substitute tho mechanical
VFU in the printer. It is composed
of a 5-bit counter that is loaded on
receipt of a vertical format command
with the respective number of vertical
lines requested. A list of vertical
format characters and their coding will
be found just be'fore Section 7 (Tables).

6.3.3.9

Shift Counter (Character Shifting\

In the 5/7 ASCI~ mode, the data is
packed with five characters/35-bits.
After the five characters ha"e been
loaded into the' data buffer, the shift

With this test, a very extensive

Using aoIOT 6542, a check can be made

Program Interrupt
The control has a program interrupt
facility which can be enabled by IOT

enabled, the PI request will be made
when the done or error flag is present.

This section of the control allows
the diagnostic programmer to
exercise the interface in a manner
which closely resembles actual
"on line" printer operation, without
a line printe.r. ~1>.e 9Htgnostic writ~
up for insertion of M911 termJ'card .. <
This is accomplished by loading a
test print cycle in core memory and
issuing the set maintenance !OT.
This IOT simulates the data strobe
line of the interface and single
steps the data through the control.
After issuing the !OT, the program
can chack the major registers and
control functions with !OT reads
and also look at the data lines to
the printer to see if the character
was actually sent.

John L. Pratt

AP! Facility
The interface has an API ¢3 device flag
whose address is 56, This flag will
set with a done or error condition.

This section is used for checking
the error flags in the control.
Checking is accomplished by setting an individual error flag and
then checking the main error flag
by the priority interrupt and AP!
facility. These flags are: Interlock, Done, ILL HT, Line Over, Off
Line, Maintenance, and Error;
