PDP-11/40,-11/35 (21 inch chassis) system manual

This document serves as a comprehensive guide for the PDP-11/40 and 21-inch chassis PDP-11/35 computer systems. It offers a general introduction to the system, covering its installation, operation, instruction set, options, peripherals, equipment mounting, power, and maintenance.

Key areas detailed include:

• System Components and Functional Description: An overview of the basic hardware, such as the KD11-A processor, KY11-D programmer's console, MF11-L core memory, Unibus, and power system, along with descriptions of various optional memory systems and I/O devices like the LA30 DECwriter and DL11 asynchronous line interface.
• Installation Procedures: Guidance on site preparation, physical dimensions, environmental requirements, electrical connections, unpacking, inspection, cabinet installation, intercabinet and peripheral connections, and initial power-on and operational verification.
• System Operation and Programming: Instructions for using the programmer's console and input/output terminals (LA30 DECwriter, ASR 33 Teletype), basic power-on and console control, manual and automatic program loading, running programs, and fundamental programming techniques.
• Processor Instructions and Options: A summary of the PDP-11 instruction set, including address modes, basic and extended instruction sets (EIS, FIS), and various processor options like memory management (KT11-D) and line time clock (KW11-L).
• Equipment Mounting and Power: Detailed information on the BA11-FC Mounting Box, module allocations, cabinet configurations, and the power system components, including the power controller, supplies, and regulators.
• General Maintenance: Techniques for overall system maintenance, a list of required equipment, preventive maintenance procedures (physical and electrical checks), and an extensive list of diagnostic programs for error detection and isolation.

The manual acts as a central resource, referencing other specialized documentation and engineering drawings for more in-depth technical explanations, enabling users to understand, operate, and maintain these PDP-11 systems effectively.
