Field Installation and Acceptance Procedure for KM8-A

This document provides technical specifications, installation, and acceptance procedures for the KM8-A option board, which is designed for use with the PDP-8/A computer.

Summary:

• Installation & Testing: The document outlines the physical installation process, which involves installing the KM8-A board into the second or third slot of the Omnibus, setting the appropriate switches, and verifying functionality using diagnostic routines.
• Component Details: The document includes comprehensive circuit diagrams, logic schematics, and parts lists for the M8317 Option Board #2. It details the various "bus buffers" and control logic required for memory management and time-sharing functions.
• Configuration & Programming: Detailed tables provide switch settings for "Bootstrap/Auto-Restart" sequences and memory addressing. Additionally, the document covers ROM programming directions, explaining how the two 256x4 ROMs are combined to manage 16-bit word operations, along with examples for programming both auto-restart and bootstrap sequences.
• Flowcharts: The document contains operational flowcharts that depict the logic path for instructions (such as IOT operations and memory referencing) and how the system manages status updates and interrupt handling.
