PDP-8 Diagnostic Programs Index By Options

Summary

This document is a technical reference memorandum, dated January 23, 1973, from Larry Goelz of Digital Equipment Corporation's (DEC) Computerpac Support department. It serves as an index and guide for PDP-8 family diagnostic programs ("Maindecs").

The document is organized to help users identify which diagnostic programs are required for specific hardware options. It includes:

• Indices: A primary index mapping hardware options to their corresponding diagnostic programs, followed by a list of Maindecs with their titles.
• Operating Instructions: Brief abstracts, requirements, storage locations, loading methods, and starting procedures for each diagnostic program.
• Switch Register Options: Descriptions of the switch register settings used to configure or control the execution of individual tests.
• IOT Code Tables: A comprehensive reference table at the end of the document detailing Input/Output Transfer (IOT) codes and their functions for various PDP-8 hardware components, including disk drives, magnetic tape units, and display controllers.

The memorandum notes that this is a "first pass" document and warns that it may contain minor errors, such as missing options or outdated Maindec numbers, with plans for future updates and release to the Program Library.
