RL01/RL02

This document provides the technical details, operating instructions, and code listing for the RL01/RL02 Performance Exerciser (diagnostic code AC-F374B-NA). The program is designed to test the operational reliability of one to four RL01/RL02 disk drives by simulating a user environment with random overlapping seeks, reads, and writes.

Key features include: * Operating Modes: Includes 'Accept Mode' for standard testing and 'Manual Intervention Mode' for hardware debugging. * Error Handling: Detailed logging of fatal and soft errors, with the ability to define retry limits and drop drives that exceed error thresholds. * System Requirements: Requires a PDP-8 or VT278, at least 8K of memory, and appropriate disk controllers. * Diagnostic Procedures: Includes routines for disk initialization, bad sector file checking, power fail recovery, and extensive register/status bit definitions.
