KXT11-CA Single-Board Computer User's Guide

This document is the official user's guide for the KXT11-CA single-board computer (SBC), also known by its part number M8377. The guide provides technical details for hardware and software engineers involved in applying, programming, and maintaining the SBC. It covers the board's two main operating modes: standalone mode, for use as a dedicated controller or microcomputer; and peripheral processor mode, for use as an intelligent processor interfaced with a 22-bit Q-Bus system.

Key contents include: - Architecture and Hardware: Detailed functional blocks including the T-11 16-bit microprocessor, Q-Bus interface, DMA transfer controller (DTC), and I/O capabilities (serial and parallel). - Theory of Operation: Technical analysis of the board's internal buses, interrupts, timing, and Q-Bus interface. - Native Firmware: Description of the bootstrap, selftest, and macro-ODT routines contained in the on-board PROM. - Programming Information: Documentation for software-programmable registers, including control status registers (KXTCSR A-D), the two-port RAM (TPR), and DTC management. - Configuration, Installation, and Maintenance: Procedures for jumper configuration, backplane installation, and diagnostic testing using standard loopback connectors. - Instruction Set: Extensive appendices documenting the PDP-11 instruction set as emulated by the T-11 processor, addressing modes, and performance parameters.
