Octal Debugging Technique

From Wikipedia, the free encyclopedia

For other expansions of "ODT", see ODT.

Octal Debugging Technique, or ODT, was the name of several debugger programs originally developed for DEC hardware. Various software systems including OS/8, RT-11, RSX-11, and RSTS/E implemented ODT as did the firmware console of all of the LSI-11-family processors including the 11/03, 11/23/24, 11/53, 11/73, and 11/83/84.

The debugger allowed access to memory using octal addresses and data. Within the software systems, the debugger accessed the process's virtual memory. The firmware console implementation accessed physical memory.
