This document is an Illustrated Parts Breakdown (IPB) for the Digital Equipment Corporation's 220QS Pedestal System, published on December 17, 1990.

Its primary purpose is to provide a comprehensive guide for identifying and locating all components and assemblies of the 220QS Pedestal System, structured according to its engineering drawings.

Key contents of the document include:

• Usage Instructions: A detailed explanation on how to use the IPB, covering its general organization, major assembly locator, indented parts lists, and column callout descriptions.
• Illustrated Diagrams: Exploded view diagrams showing the overall 220QS Pedestal System and its various sub-assemblies, such as the Bulkhead Assembly, Base Assembly, Enclosure Assembly, and Front Panel Assembly, with numbered callouts for each component.
• Detailed Parts Lists: Corresponding tables that list each part by figure and item number, providing a description, Digital Equipment Corporation (DEC) part number, ECO cut-in information, and cross-references. These lists also include accessory kits and various labels.
• Indexes: Comprehensive indexes allowing users to look up parts either numerically by DEC Part Number or alphabetically by Part Description.

The IPB is designed to help users identify parts, understand their hierarchical relationships within higher assemblies, and facilitate the selection of alternate parts if a direct replacement is not immediately available.
