KY11-R Family of Electronic Consoles User Guide

This document is a User Guide for the KY11-R Family of Electronic Consoles, designed to add remote diagnosis capabilities to PDP-11/70 computer systems. It replaces the traditional front panel, allowing system operation, monitoring, and control through commands typed at a system terminal.

Key aspects of the document include:

• Components & Microcode: It describes the console's hardware components (microprocessor, multiplexer, modem) and two microcode versions (V01 and V02) that define its command syntax and functions.
• Operation: The guide details operating procedures, including system power-up, self-tests, bootstrapping, and managing various operating states (Console, Program I/O, Talk).
• Commands: It provides a comprehensive list and explanation of commands for CPU control, examining and depositing memory/register data, and performing system maintenance.
• Troubleshooting: Procedures for identifying and reporting hardware malfunctions to the DDC are outlined, covering both electronic console and general system failures.

Overall, the document serves as a comprehensive manual for operators and field service personnel to effectively manage, control, and diagnose PDP-11/70 systems equipped with the KY11-R electronic console.
