PDP-11/04 System User's Manual

This document is the PDP-11/04 System User's Manual, published by Digital Equipment Corporation (DEC) in December 1976.

The manual provides comprehensive information for users of the PDP-11/04 computer system, covering:

1. System Description: Details the core components including the KD11-D Central Processor, Unibus architecture, M9301 Bootstrap/Terminator module (which enables console functions via a system terminal), M9302 Terminator, various types of MOS and Core memory, and system mounting boxes. It also lists optional equipment.
2. Operation: Explains how to interact with the system using the basic Operator's Console (KY11-LA) and the optional Programmer's Console (KY11-LB). It details console switches (Power, HALT/CONT, BOOT/INIT) and indicators, and introduces the console emulator routine in ROM, which allows commands like LOAD, EXAMINE, DEPOSIT, START, and BOOT from a terminal.
3. Functional Description: Describes key system functions such as Halt-Continue, Boot-Initialize, and Power-Up Reboot Enable, and provides a detailed look at the console logic and the M9301 Bootstrap/ROM firmware, including built-in CPU diagnostics and bootstrap programs for peripheral devices.
4. Configuration: Guides the user through setting up the system, detailing backplane physical and electrical connections, module placement, and the settings for various switches and jumpers on modules like the CPU, M9301, DL11-W (serial line interface), memory modules, and parity controller.
5. Installation: Covers site considerations (humidity, temperature, acoustics, static electricity), electrical requirements, unpacking procedures, initial inspection, and a first-time start-up procedure, including a quick verification routine.
6. Troubleshooting: Offers a summary of operational and installation notes, along with quick verification routines and flowcharts to help identify and resolve common system problems.

The manual is intended to assist users with system configuration, installation, daily operation, component familiarization, and basic troubleshooting.
