FIS BOARD

This document provides a comprehensive technical description of the "FIS BOARD" (Floating Instruction Set Board), which is part of the KE11-F option for the KD11-A processor. It includes detailed schematics illustrating the interconnections of various integrated circuits (e.g., 7408, 74194, 74H04, 74153) responsible for functions such as signal routing, memory/high-speed register operations, bus interfacing, and control logic.

General notes specify pin notation conventions, signal prefix meanings, electrical units (ohms for resistance, picofarads for capacitance), and installation instructions. A substantial portion of the document comprises "FLOWS STATE ADR" tables, which define microcode or control word outputs for different processor states, detailing the logic levels of numerous control signals (e.g., WR, CB, BUS, ALU, SPS). Additionally, the document contains a software list outlining instruction tests, exercisers, and GTP overlays for the Floating Instruction Set, as well as a parts list identifying the FIS Board and associated module utilization.
