PDP-11/05-S, 11/10-S system manual

This manual provides a comprehensive overview of the PDP-11/05-S and 11/10-S computer systems, detailing installation, operation, instruction set, and maintenance. The PDP-11/05-S is designed for Original Equipment Manufacturers (OEMs), while the 11/10-S is for End Users, offering more bundled software and services; both are electrically identical.

Key components include the BA11-K Mounting Box (housing the H765 Power Supply), a nine-slot backplane, the KD11-B Processor (comprising M7260 Data Path and M7261 Control Logic modules), the KY11-J Programmer's Console, the MM11-U Core Memory System, and the Unibus for high-speed communication between components. The KD11-B Processor handles instructions, arithmetic/logic operations, Unibus allocation, features 16 hardware registers, and supports a 16-bit word length with an 18-bit Unibus address space for software compatibility. The memory system provides 16K (16,384) 16-bit words, byte-addressable.

Installation guidelines cover environmental requirements (temperature, humidity, static electricity), electrical specifications (115V or 230V AC, 575 VA min), physical unpacking, inspection, and mounting in an H950 cabinet. It also outlines initial power-on procedures and recommends running system diagnostics for certification.

System operation is primarily controlled via the KY11-J Programmer's Console, which includes a power key switch, function switches (Load Address, Examine, Deposit, Enable/Halt, Start, Continue), and Address/Data switches/indicators. The manual describes procedures for manual and automatic program loading (including bootstrap and absolute loaders), memory dumps (DUMPIT for octal, DUMPAB for binary), and executing programs.

The instruction set of the KD11-B processor is detailed, covering addressing modes (direct, deferred, PC addressing) and instruction groupings (single/double operand, program control, operate group, condition codes operators). Programming differences between the PDP-11/05/10-S and other PDP-11 series processors are also noted.

The power system chapter elaborates on the H765 Power Supply's components and power flow, emphasizing voltage regulator output specifications crucial for system expansion. System expansion methods are described for Small Peripheral Controllers (SPC), System Units (SU), and additional BA11-K Expander Boxes, covering physical installation, power, and data connections.

Maintenance information encompasses a general philosophy, required equipment (including KM11 Maintenance Modules and module extenders), preventive maintenance (physical and electrical checks, clock adjustments), and troubleshooting procedures that involve initial investigation, preliminary checks, and running diagnostic programs.
