MP-KL10-A1 KL10 vol1 Sep75

This document is a "FIELD MAINTENANCE PRINT SET" for the "ARITHMETIC PROCESSOR" (MP-KL18-AD) from Digital Equipment Corporation, published in 1975. It covers unit variations KL18-AA and KL18-AB.

The document includes a table of contents that lists various components and assemblies, their drawing numbers, and descriptions. These include: - Arithmetic Processor components (power supplies, regulators, heat sinks, etc.) - Cabinet assemblies (doors, panels, fan, filter, casters, levelers) - Console Processor parts (async. line interface, DecTape, Massbus controller, peripheral mounting panel) - Massbus and I/O components (bus adapter, backplanes, switch assemblies, cooling, memory, etc.) - Logic and CPU assemblies, including power supplies, regulators, backplanes, and specific boards (shift matrix, data path, cache control, memory buffer, physical memory address module, bus translators, paging board, control registers, clock control).

It also contains various connection charts, wire tables, and schematics detailing the wiring, power distribution, and component layouts for different parts of the arithmetic processor, including: - Harness connections for various modules (power supply, CPU, Massbus, I/O). - Cable conversion plate assemblies. - Power and regulated power supply diagrams. - Wiring diagrams for specific modules like the console processor, Massbus, and various backplanes. - Detailed views of chassis, cabinet, and panel layouts with component locations. - Specifications for components like resistors, capacitors, and various hardware items (screws, washers, nuts, clamps, labels, etc.).

Essentially, it's a comprehensive technical manual providing the necessary information for the maintenance and understanding of the arithmetic processor's hardware and interconnections.
