VAX 4000 Model 100 System IPB

This document is an Illustrated Parts Breakdown (IPB) manual for the VAX 4000 Model 100 System.

Its primary purpose is to help users identify parts and their locations within the hardware product. The manual is structured around:

1. Illustrated Figures: These show exploded views of assemblies (like the enclosure, base, and cover) with numeric callouts pointing to individual parts.
2. Associated Parts Lists: For each figure, detailed tables provide:
   • Figure and item numbers.
   • Part descriptions (including indicators for subassemblies).
   • Digital/Vendor part numbers (DEC Part No.) with revision levels.
   • Engineering Change Order (ECO) cut-in information.
   • Usage codes and cross-references to other figures.
3. Indexes: Comprehensive indexes are included, allowing users to look up items by DEC part number (numerically) and by part description (alphabetically), cross-referencing them back to their figure and item numbers.
4. ECO/Revision History: A table tracking changes to the assemblies and the document itself, including initial and current levels, and printing dates.

The document also contains standard copyright and trademark information, disclaimers, and a reader's comments form for feedback.
