PDP-8/E Instruction Test 2

This document outlines the usage and functionality of the PDP-8/E Instruction Test 2 program (MAINDEC-8E-D8BB). The program is designed to perform extensive verification of several PDP-8/E instruction set features, including autoindexing, indirect addressing, and the DCA instruction, along with minimal testing for interrupt operations and processor IOT instructions.

The document provides: * System Requirements: Details for the necessary PDP-8/E hardware, storage locations, and prerequisite diagnostic programs. * Operational Procedures: Instructions for loading the binary, starting the test, and handling error states, including recovery methods via oscilloscope investigation. * Test Organization: A breakdown of the testing sequence, grouped by functional classification (DCA, Indirect Addressing, Autoindex, IOT, and Interrupt tests). * Technical Implementation: Detailed assembly-level code listings for the test suite, complete with comments and register state expectations for error condition validation.
