PDP-10 Monitor Course Materials

This document serves as a collection of course materials for the PDP-10 Monitor. It covers key architectural and operational concepts, including:

• Priority Interrupt System: Programming techniques for the seven-channel priority interrupt system.
• Monitor Structure: The cyclic nature of the monitor, including the Command Processor, Scheduler, and Swapper.
• Monitor Data Base: Descriptions of key tables like JBTQ (Job Queues), JBTADR (Job Address), and JBTSTS (Job Status).
• I/O Processing: Management of input/output operations, including buffered I/O, device data blocks (DDB), and interrupt handling.
• Allocation of Core: Procedures for swapping and core management in a time-sharing system.
• The Scheduler: Mechanisms for job scheduling and queue management.
• The Swapper: Logic and flow for swapping jobs into and out of core.
• Scanner Service: Handling Teletype I/O via the scanner service and interrupt routines.
