PDP-11/70 Multiprocessor Technical Manual

This document is a preliminary technical manual for the PDP-11/70 Multiprocessor system. It provides detailed information on:

• System Overview: The configuration of the multiprocessor system, including the use of modified KB11-C processors and multiported MK11 memory.
• Interprocessor Communication: Detailed description of the Interprocessor Interrupt and Sanity Timer (IIST) subsystem, which facilitates communication and error detection between processors.
• System Components: Functional descriptions of basic components like the IIST interface module (M8717), memory configurations, Massbus operation, and shared Unibus switching (DT07).
• Operation and Configuration: Guidelines for configuring the multiprocessor system, setting up memory options, and using the BOOT/IIST switch panels for system management.
• Maintenance and Diagnostics: Coverage of maintenance registers, error detection, and diagnostic capabilities for ensuring system reliability.

The manual is intended to assist in the installation, operation, and maintenance of the multiprocessor configuration.
