PDT-11/110 and PDT-11/130

This user guide provides comprehensive documentation for the Digital Equipment Corporation PDT-11/110 and PDT-11/130 terminal-based computer systems. It introduces the systems' design for data entry and terminal applications, built around the LSI-11 microprocessor, and covers their general operation, configurations, and software licenses.

The document details operational procedures, including keyboard and monitor controls, audible indicators, power-up sequences, self-test programs, and program loading routines for both PDT-11/110 (Terminal Boot Loader or MOP loader) and PDT-11/130 (mass storage tape drive). It explains tape cartridge handling and describes system SET-UP modes with various configurable features like display characteristics and communication settings.

Furthermore, the guide includes instructions for unpacking, installation, and maintenance, alongside detailed hardware specifications. It provides extensive interface information, covering serial line device connectors, electrical characteristics, voltage inputs/outputs, pin assignments for communications, printer, and optional cluster connectors. The programming section delves into system architecture (processor, memory, peripheral interfaces, mass storage), system characteristics (interrupts, device registers), character sets, control functions, and communication protocols. Appendices offer ANSI definitions, system throughput calculations, and key code generation details.
