RPR02 Engineering Drawings 197602

This document is the RPR02 660-1 Disc Pack Drive Logic and Schematic Manual (Document ID: EK-RPR02-LS-V01), originally produced by Memorex Corporation and reprinted by Digital Equipment Corporation (DEC). The latest revision date noted within the document is January 17, 1975.

The manual serves as a comprehensive technical reference, detailing the internal logic, circuitry, and physical components of the RPR02 660-1 Disc Pack Drive.

Key contents include:

• Machine Level Control Chart: A detailed inventory of the drive's major components, listing specific PC boards (categorized by rows A, B, C, and Top Deck Plate), assemblies (e.g., logic, control panels), harnesses, and power supply units, along with their respective part numbers and engineering change levels.
• Logic Manual Index: A comprehensive table of contents providing drawing numbers and titles for a wide range of schematics and logic diagrams. These cover:
  • System-level block diagrams (e.g., overall system, servo, read/write, power and sequence control).
  • Detailed logic for critical functions like servo sequencing, adder/speed decode, cylinder/present address registers, head selection, power-up sequencing, and various delay timers.
  • Schematics for different types of amplifiers (read/write, transducer) and drivers (lamp, servo, actuator, line).
  • Diagrams for power distribution, heat sinks, and interconnects/wiring.

The document is highly technical, providing an in-depth look into the electronic and logical architecture of the disc pack drive.
