LK03A KEYBOARD

This document is an Illustrated Parts Breakdown (IPB) for the LK03A KEYBOARD, compiled according to engineering drawing standards. It serves as a guide to identify all parts and assemblies of the keyboard. The document includes a Major Assembly Locator as an initial index to all illustrations. Parts are presented in an indented list format, where asterisks denote the subordination of items to higher assemblies, helping users identify next higher assemblies and alternative components.

Key information provided for each part includes:

• Its figure and item number.
• A description and pertinent specifications.
• The Digital Equipment Corporation (DEC) ordering number.
• The Engineering Change Order (ECO) level at which the IPB was prepared, with subsequent ECOs indicated for modified parts.
• Vendor codes/part numbers for non-DEC stocked items.
• "Used On Code" letters to specify option variations a part is used in.
• A cross-reference to figures for next higher assemblies or detailed breakdowns.

The IPB also explains the use of symbols: hardware designators (like S for screws), the '@' symbol for attaching hardware not integral to the assembly, and "(NFR)" for items that are Not Field Repairable.
