OCTMON - An Octal Monitor for the PDP-S Computer
8-298

Peter Lemkin, National Institute of Health, Bethesda,

OCTMON is an octal debugging monitor for the PDP-8 that
facilitates debugging for machines with several memory fields.
It is relocatable within a field, and may be put in any field.
It uses 1400 (octal) locations and 13 (octal) locations in page
0 of its resident field. It also uses 11 (octal) locations of any
other field in which there is a breakpoint. Only one restorable
breakpoint is allowed at any time and may be in any
field. There are options to dump out sections of memory,
punch and read bin tapes, enter octal numbers into memory,
start the program being tested, and enter a number into the
MQ. The monitor will work without EAE, extended memory
and without DECTAPE/DISK systems.
