RSX-11D System Overview

This document outlines the architecture and features of the RSX-11D real-time operating system, designed for the PDP-11/45. It details key concepts such as tasks, memory partitioning (user and system control), disk usage, and multiprogramming. The document explains how the system handles task scheduling, priority-based multitasking, and event-driven operations using event flags. Additionally, it covers system traps, on-line task development, the Monitor Console Routine (MCR), system directives, and I/O handlers, providing an overview of how these components function together in a process control and laboratory environment.
