TU60 Field Maintenance Print Set

This document is a comprehensive technical documentation set for the Digital Equipment Corporation (DEC) TU60 (and related TU6S) cassette drive unit, primarily dated from the early to mid-1970s.

The collection includes:

• A primary Drawing Directory/Customer Print Set Index (Page 1) listing all included drawings by title and drawing number, along with unit variations (e.g., 115V vs. 230V configurations).
• High-level block diagrams and assembly breakdowns (e.g., Page 2 for the TU60 Unit Assembly), illustrating how various sub-assemblies connect.
• Detailed parts lists for both electrical and mechanical components, breaking down assemblies into their constituent parts with drawing numbers, descriptions, and quantities (Pages 3-4, and scattered throughout for specific assemblies).
• Numerous circuit schematics for key electronic modules such as the TU60 Logic (M7760, Pages 5-8), Read/Write and Servo (M7761, Pages 9-13), H751 Power Supply (Pages 15-18, 22-23), and the Terminator (Page 14).
• Wiring diagrams for the cassette drive (Page 24) and internal power connections.
• Detailed mechanical assembly drawings for various components and sub-assemblies, including the main TU60 Unit Assembly (Pages 19, 25-26), Transport Assembly (Pages 28-29), Base Assembly (Page 31), Switch Assembly (Page 32), Spindle/Pulley Assemblies (Page 33), Motor Mount/Drive-Motor Assemblies (Pages 34-35), and Lever/Rocker Assemblies (Page 36).

The document provides a complete technical reference for manufacturing, assembling, and understanding the TU60 cassette drive and its various sub-components.
