Pdp-8/e Instruction Test 1

This document is a diagnostic program manual for the PDP-8/E computer, created in May 1971 by Ed Fortmiller. The program is designed to test the AND, TAD, operate, and basic MQ instructions of the PDP-8/E.

Key aspects of the document include:

• Requirements: Testing requires a PDP-8/E equipped with a teletype. The program uses memory locations 0000–5314.
• Procedure: The program is loaded using the standard binary loader, initiated by setting the switch register to 0200 and pressing "Load Address," then setting it to 7777 and pressing "Clear and Continue."
• Operations: The program runs a sequence of tests, including individual operate functions, TAD, rotate functions, BSW, Group 1 and 2 operate instructions, and MQ instructions.
• Feedback: The program runs until a stop or an error is encountered. It provides audible confirmation of progress by ringing the teletype bell approximately every five seconds at the end of 1440 program passes.
• Error Recovery: If a specific test causes an error, users can loop that test by replacing the instructions preceding the halt (HLT) with a jump (JMP) back to the beginning of that test.

The document concludes with a full assembly listing of the code, memory constants, and symbol tables.
