Multi8 System Manual

The MULTI8 System Manual provides a detailed overview of the MULTI8 operating system, designed for PDP-8 computers. The system features a foreground/background architecture where the foreground handles real-time tasks managed by the Monitor, and the background supports timesharing operations. This manual covers system components, interrupt handling, multi-tasking primitives, memory allocation, and provides guidance for writing and configuring tasks, including specific assembly language conventions and examples for using the system's monitor calls.
