This document is the Parts Catalog for the MODEL 733 DEC Disk Storage Drive, published in January 1976 by Information Storage Systems, Inc. (ISS), a Sperry Univac company.

The catalog serves as a comprehensive guide for identifying and illustrating components, assemblies, and detailed parts necessary for the maintenance of the disk drive.

It is organized into three main sections:

1. Introduction: Provides instructions on how to effectively use the catalog, including explanations of its columns and conventions.
2. Group Assembly Parts Lists: Offers detailed breakdowns of assemblies, typically presented in the order of disassembly. This section includes illustrations and listings for major components such as the drive machine, sliding cover, baseplate, motor, carriage, various frames, control panel, power supply, electronic gate matrix, and numerous printed wiring assemblies (PWAs) like regulators, servo amplifiers, and data control boards. It also covers specialized items like resonant capacitors, filters, harnesses, and diagnostic tools. Parts are specified with quantities, descriptions, and reference designations. Note is made for components applicable to both 50 Hz and 60 Hz drive configurations, as well as 'Not Field Replaceable' (NFR) items and proprietary parts.
3. Part Number Index: A complete numerical index of all part numbers listed in Section 2, providing cross-references to their corresponding figures and index numbers.
