Illustrated Parts Breakdown 655QR Pedestal System

This document is an Illustrated Parts Breakdown (IPB) manual for the Digital Equipment Corporation 655QR Pedestal System, initially published on January 30, 1990.

Its primary purpose is to provide a comprehensive guide to the system's components and assemblies. Key contents include:

• Detailed Parts Lists: Breakdowns of assemblies and their constituent parts, including descriptions, Digital part numbers, and figure references. A hierarchical indentation system (using asterisks) denotes the subordination of parts within assemblies.
• Illustrations: Diagrams of the 655QR Pedestal System and its major sub-assemblies (e.g., Chassis, Bulkhead, Panel, Base, Enclosure) with numbered callouts corresponding to the parts lists.
• Usage Instructions: A "How To Use" section explains the manual's organization, interpretation of part descriptions, ECO (Engineering Change Order) levels, and "Used On Code" for variations (e.g., 120V/240V, with/without skins, Timeshare/Server configurations).
• Indexes: Parts are indexed both numerically by DEC Part Number and alphabetically by description for easy lookup.
• Revision History: Details the manual's printing and ECO levels.
• General Information: Includes copyright details and trademarks of Digital Equipment Corporation.

The initial page (Page 1) features a large graphic with "655QR" indicating the product name, surrounded by repeating "X" patterns.
