This document is the KY11-LB programmer's console/interface module operation and maintenance manual (EK-KY1LB-MM-001), published by Digital Equipment Corporation in January 1977.

The manual provides comprehensive information on the KY11-LB, which functions as a programmer's console and interface for PDP-11/04/34 processors (KD11-D, KD11-E, KD11-EA). It covers:

1. Operation: Instructions for using the KY11-LB in both "console mode" (for general programming and debugging) and "maintenance mode" (for troubleshooting hardware).
2. Technical Details: A detailed theory of operation for the M7859 interface module, including its Intel 8008 microprocessor, memory organization (ROM and RAM), Unibus control logic, and keypad/display functionalities. It also describes the microprocessor's instruction set.
3. Maintenance: Guidance on using the programmer's console as a diagnostic tool for the PDP-11/04/34 processors and provides troubleshooting and maintenance procedures for the KY11-LB module itself, including installation instructions.
