Monitor Systems 10/20, 10/30

This manual provides detailed technical information for programmers working with the single-user Monitor on PDP-10/20 and PDP-10/30 systems. It covers the following key areas:

• Monitor Operations: Explains the command language used to interact with the monitor, including functions like program execution (RUN, START, CONT), saving/loading (SAVE, GET), device management (ASSIGN, DEASSIGN), and debugging (DDT).
• User Programming: Describes how to interface with the monitor using programmed operators (UUOs), including how to perform I/O, manage files, and handle error conditions.
• Input/Output Programming: Details the monitor's approach to device-independent I/O, including buffered and unbuffered (dump) data transmission modes and buffer management.
• Device Dependent Functions: Provides specific information for standard devices like Teletype, paper tape, line printers, card readers, magnetic tapes, DECtape, and disk storage.
• System Customization: Includes instructions on using the System Builder to generate a customized monitor configuration for specific installation needs.

This manual was issued in January 1968 and serves as a fundamental guide for system programming and hardware-software interaction for the specified PDP-10 configurations.
