PDP-12 CP Test III

This document serves as the technical manual and diagnostic listing for the PDP-12 CP Test III. The program is designed to test LINC mode instructions, including special function registers, D J R, M U L, L D F, and L I F interrupt inhibits. When executed, the program runs continuously, performing diagnostic tests and ringing the TTY bell every 10 seconds upon the successful completion of a pass.

The document includes:

• Requirements: A standard PDP-12 computer with an ASR-33 teletype or equivalent.
• Operating Instructions: Loading and starting procedures (starting at memory location 400).
• Technical Reference: A comprehensive assembly language listing of the test code, including detailed instruction definitions, memory reference operations, and specific diagnostic subroutines for addressing modes, arithmetic, and logic tests.
• Diagnostics: Detailed error-handling documentation, noting that any halt indicates an error, with specific error explanations provided within the listing.
