Memory Address Test

This document describes the Memory Address Test (MAINDEC-08-D1B0-D), a diagnostic tool for the PDP-8 computer. The test ensures that the memory addressing circuits are functioning correctly by performing read/write checks in both forward and reverse directions.

Key contents include: - Requirements: Standard PDP-8 computer. - Procedures: Instructions for loading and starting the diagnostic in low or high memory storage. - Error Handling: Explanation of error printout formats and a diagnostic instruction loop for troubleshooting. - Program Logic: The test operates in four phases, setting memory contents to match their addresses to identify faulty selection circuitry.
