Illustrated Parts Breakdown TU80 Tape Drive

This document is an Illustrated Parts Breakdown (IPB) for the TU80 Tape Drive, published by Digital Equipment Corporation. It serves as a comprehensive guide for identifying, ordering, and understanding the components of the TU80 Tape Drive, covering various configurations (e.g., 120V/60Hz, 240V/50Hz) and design revisions.

The document begins with instructions on "How to Use the IPB," detailing sections such as the Major Assembly Locator, Indented Parts List, Column Callout Description, ECO Cut-In explanations (for engineering change orders), Vendor Code/Part Number, Used On Code (for option variations), cross-references to other figures, and symbol usage for hardware designators.

The main content consists of numerous exploded-view diagrams (Figures 1 through 30) illustrating different assemblies of the tape drive. These include the main Tape Drive Assembly, Cabinet Assembly and its sub-assemblies (Trim, Front Door, Filler Panel, Bottom Cover, End Panel, Shielded Rear Door, Stabilizer, Cabinet Accessory Kit), Equipment Assemblies (Top and Bottom), Air Bearing Assemblies (Rear and Front), Motor Assemblies, various Cable Assemblies, and the Power Amp Board Assembly. Each figure is accompanied by a detailed parts list, providing item numbers, descriptions, DEC part numbers, vendor part numbers, ECO cut-in information, and usage codes.

The document concludes with extensive "TU80 Sorted by DEC Part Number" and "TU80 Sorted by Vendor Part Number" indexes, allowing users to quickly locate specific parts. Throughout the manual, notes emphasize referring to the figure parts list for the latest descriptions, especially for items marked as "added" or "deleted" due to revisions.
