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. A debugger is a computer program that is used to test and debug other programs. ... The DEC logo Digital Equipment Corporation was a pioneering American company in the computer industry. ... OS/8 was the primary operating system used on the Digital PDP-8 minicomputer. ... RT-11 (for Run Time or Real Time) was a real-time operating system for the DEC PDP-11. ... RSX-11: A family of real-time operating systems mainly for PDP-11 computers created by Digital Equipment Corporation (DEC), common in the late 1970s and early 1980s, designed for and much used in process control, but also popular for program development. ... RSTS/E (an acronym for Resource Sharing Time Sharing Extended) was a multi-user time-shared operating system developed by Digital Equipment Corporation (DEC) for the PDP-11 series of 16-bit minicomputers, and used primarily during the 1970s and 1980s, although some installations were still being upgraded well into... In computing, firmware is software that is embedded in a hardware device. ... The PDP-11 was a 16-bit minicomputer sold by Digital Equipment Corp. ...
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. The octal numeral system is the base-8 number system, and uses the digits 0 to 7. ...
