DEC 1124 CONSOLE ASSY+BOX

This multi-page document provides a comprehensive set of engineering and manufacturing specifications for components of a Digital Equipment Corporation (DEC) PDP-11/24 computer system, primarily focusing on the console and a related expansion chassis.

The document includes:

• Console Assembly (P/N 7016958): Top-level physical assembly drawings showing external features, connections to the backplane and power supply, and detailed instructions for internal component placement, such as foam filters.
• Console Modules (P/N 5413885 and 5414441): Detailed printed circuit board (PCB) layouts, electrical schematics, and parts lists for two distinct console modules. These schematics illustrate control logic, switch functions (e.g., DC ON, HALT, BOOT, STANDBY), and power connections, with jumper configurations specified for different operational variations.
• Power Distribution Board (P/N 5413815): An electrical schematic detailing power line connections (+5V, +/-12V, +/-5V, +15V, GND) and signals (ACLO, DCL, LTC), along with its corresponding parts list.
• Box 5.25 BA11-L (main chassis/expansion box): Extensive mechanical assembly drawings showing the overall structure, integration of a cooling fan, chassis, enclosure, power supply, and internal wiring. Critical assembly notes cover stiffening brackets, loose-shipped items (like power cords), and fan replacement procedures.
• Console-to-Backplane Cable Assembly (P/N 7016962): Detailed instructions for cable assembly, including a wire table, pinouts, and specific notes on tubing and crimping.

Each section is supported by comprehensive parts lists (Bill of Materials) for various sub-assemblies and components. The documents frequently include revision histories, variations (e.g., -01, -03), and specific installation notes. All materials are copyrighted by Digital Equipment Corporation (primarily 1980-1981).
