and printing on the Iine printer. They all make use of the
program interrupt facility. The card punching and card reading
routines are double-buffered; i.e., one buffer may be filled
while the other is being punched. The line printing routine uses
only the buffer in the printer.

NAME:

MAINDEC 401 (Instruction Test)

ABSTRACT:

Instruction Test is a sequence of twelve programs which tests the
operation of all PDP-7 instructions except the i ot group.

Indirect

addressing and automatic indexing are also checked. Augmented
instructions are checked with the defer bit both 1 and O.
The manual loader (in locations 7762 through 7776) is used to read
in all programs. The instructions used by the loader are assumed
working only for readin purposes. These instructions are fully
checked by the Instruction Test.
In general, an instruction is not used before it is tested. However,
in order to facilitate usage, Programs 0 through 3 use instructions
wh ich have not been checked. These untested instructions are used
to sense the AC switches. This part of each program (the last six
instructions) is not an inherent part of the test and may be replaced
by a single imp.

NAME:

MAl NDEC 402 (Checkerboard)

ABSTRACTS:

Memory checkerboard is a program which creates the worst possible
noise conditions in memory.

It then starts a word by word check for

accuracy.
There are four discreet starting addresses which will produce four
PDF

different noise patterns, one of which is the worse case for the
particu lar memory stack used.

exception of 7762 to 7777 which contain the PDP-7 loader
program.
The low part checks from location 20 to 7761 and the high part
from lIOll to 7741. The low part of the program will be in
register lIOll to 20 and the high part wi /I be in 7742 and 7761 •

NAME:

MAINDEC 410 (RPB Test)

ABSTRACTS:

Read binary test program is a maintenance program for the PDP-7
photo-e lectric paper tape reader during binary operation. As the
reader reads a closed loop of tape containing alternating lines of
six lis and six OIS (77007700)8 each ~it is checked against data
stored in core memory. This program detects two types of reader
malfunction: picking up and dropping of information and feed
holes.
