Punch Test Program

This document, titled 'Punch Test Program, DEC TP-1: Operating Instructions,' provides technical guidance and the corresponding assembly language code for testing paper tape punch hardware on the DEC PDP-1 computer. It includes:

• General Test Procedures: Instructions for punching test patterns (alphanumeric and binary modes) and verifying them using a tape reader. It details error handling, specifically using the AC (Accumulator), IO register, and PC (Program Counter) to identify specific bit failures.
• Test Word Mode: Instructions for running tests that use specific test word switches, including setup for alphanumeric and binary punch modes.
• Code Listings: The complete machine assembly listing for the TP-1 program, covering address space from 0100 through 0537, including constant definitions, logic routines for checking holes/lines, and error reporting routines.
