OCTMON - An Octal Monitor for the PDP-S Computer

8-298

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.
