HSC50 IPB

This document is an Illustrated Parts Breakdown (IPB) for the HSC50 Storage Controller, published by Digital Equipment Corporation.

Its primary purpose is to provide a comprehensive list and visual representation of all components, assemblies, and sub-assemblies for the HSC50, distinguishing between "Original Design" and "Modified Design" versions.

The document is organized into figures (illustrations) for various assemblies, each accompanied by a detailed parts list. These lists provide descriptions, part numbers, and relevant cross-references, with asterisks indicating new or changed items. It also includes information on ECO/Revision history, detailing initial and current levels of components and referencing other related Digital Equipment Corporation manuals and products (e.g., HSC60, LA50, VT220). A comprehensive "Part Number/Description Index" is provided at the end to facilitate part lookup.
