RL8-A/RL02 Read/Write Diagnostic

This document outlines the diagnostic procedures for the RL8-A/RL02 Read/Write Diagnostic software. The program is designed to test RL8A or RL278 controllers and up to four connected RL02 drives on a PDP-8/E, F, or M system. It includes instructions for loading and starting the diagnostic, configuring special environments, managing operator inputs, and understanding error reporting and test results. The software ensures hardware functionality by performing read, write, and seek tests, confirming the integrity of the RL02 disk subsystem.
