RL02 Drive Compatibility Program

This document outlines the RL02 Drive Compatibility Program (AC-F370B-MA), which is a diagnostic tool used to verify that multiple RL02 disk drives on one or more subsystems are compatible with each other. The program confirms that individual drives can read, write, and over-write data on specific tracks, including adjacent track operations. The document provides instructions for program loading, requirements for hardware and software environments, and detailed error reporting procedures for fatal, soft, and hard errors. It also contains the program listing in assembly code.
