Pdp-8 Diagnostic Programs Index by Options

This document is an interoffice memorandum from Digital Equipment Corporation, dated January 23, 1973, which serves as a preliminary reference for PDP-8 diagnostic programs.

The document provides:

• Index of Options and Maindecs: A comprehensive list mapping specific system options to their corresponding diagnostic programs (Maindecs).
• Program Abstracts and Procedures: For many of the listed diagnostics, the document includes a brief abstract describing the purpose of the test, as well as required hardware, loading instructions, starting procedures, and common switch register options.
• IOT Instruction Table: The latter portion of the document provides a technical reference table listing various hardware options, their associated mnemonic codes, and the specific IOT (Input/Output Transfer) functions they perform.

The author notes that this is a "first pass" document containing some minor errors and missing some recent option updates, and it is intended for future release in a more polished form.
