Illustrated Parts Breakdown

This document is an Illustrated Parts Breakdown (IPB) manual for the Digital Equipment Corporation PC100 Rainbow 100 System Unit, copyrighted 1983-1985. Its primary purpose is to assist users in identifying and ordering replacement parts for maintenance and repair. The manual is organized according to engineering drawing structure, featuring a Major Assembly Locator for navigation and detailed indented parts lists. These lists provide descriptions, Digital Equipment Corporation (DEC) part numbers, ECO cut-in levels, and codes indicating which options use specific parts. The document also explains various symbols used for hardware designators, attaching hardware, and non-field repairable items.

The IPB includes exploded-view diagrams and corresponding parts lists for the system unit's core components, such as the CPU assembly, fan bracket, bottom enclosure, power supply, and connector panel. It also details various options like memory adapters, Winchester disk drives, extended communication, and color graphics. A dedicated section (Purchasable Parts List) provides comprehensive information on ordering parts, available spares kits, cables, tools, maintenance documentation, and outlines Digital's customer support services, including educational services, software services, field service, and the Customer Returns Center (DECmailer program). Parts purchasable from Digital's Peripherals Supplies Group are explicitly marked.
