LK11 Engineering Drawings 197905

This document is a comprehensive collection of engineering drawings and specifications, primarily functioning as a "Drawing Directory" and "Customer Print Set Index" for several related Digital Equipment Corporation (DEC) assemblies, dated 1975.

The main assembly covered is the LK11 ASSEMBLY (Print Set LK11-0). Its directory indicates it includes documentation for:

• The LK11 Assembly itself.
• A "DRAWING DIRECTORY, LK04" (referencing a sub-assembly).
• "PUSHBUTTON INT." which corresponds to the M7060 Push Button Control.
• A "SHIPPING LIST" for the LK11.

Detailed print sets are also provided for its major sub-assemblies and components:

• M7060 PUSH BUTTON CONTROL (Print Set M7060-0): This set contains a parts list, etch circuit board layout (5011052), and circuit diagrams for the push button register, lamp data register, interrupt control, address decodes, and vector address.
• LK04 ASSEMBLY (Print Set LK04-0): This set details the LK04 assembly, including a "PUSHBUTTON PAD" (5411054), a "DC CONVERTER" (W771), and a "PUSHBUTTON CABLE" (7010579).
• 5411054 PUSH BUTTON PAD (Print Set 5411054-0): This set includes a parts list, etch circuit board layout (5011053), and circuit diagrams for push button latches, push button data control, push button detect, and lamp control.
• W771 5V TO 15V CONVERTER (Print Set W771-0): This set provides a parts list, etch circuit board layout (5011460), and a circuit diagram for the 5V to 15V conversion.
• 7010579 PUSHBUTTON CABLE: This set includes a wire table and physical diagram for the cable.

In summary, the document provides top-level and sub-assembly drawing directories, individual parts lists, detailed circuit diagrams, physical layouts of etch circuit boards, and mechanical specifications for various interconnected components comprising the LK11 system.
