DEC-00-RS64-DB RS64 Disk File Maintenance Manual

This document is the RS64 Disk File Maintenance Manual, published by Digital Equipment Corporation (DEC) in June 1971.

The manual provides comprehensive instructions for interfacing, installing, operating, and maintaining the RS64 Disk File. It is intended for maintenance personnel with a basic understanding of disk files.

The RS64 Disk File is described as a fast, random-access data storage unit offering up to 1.28 million bits of storage per unit, expandable to 5.12 million bits when up to four units are connected to a single controller. Key features include a 10-inch nickel-cobalt plated disk utilizing 32 fixed read/write heads, a self-synchronizing clock recovery system, and write protection for data tracks. It uses NRZI recording at up to 1700 bits per inch (bpi). The unit is designed for standard 19-inch rack mounting and can provide power to an external controller.

The manual is organized into chapters covering: general information, installation and operation, theory of operation (including module descriptions), interfacing details (bus voltage, signals, format, synchronizing logic), and maintenance procedures (test equipment, preventive and corrective maintenance, removal/replacement, and spare parts). It also includes detailed drawings and appendices on the RC11 format, timing track writer, and power supply.
