PDP-11/23-Plus

This document is the PDP-11/23-PLUS System Manual, published by Digital Equipment Corporation in January 1982.

Its primary purpose is to provide users with comprehensive information on the operation, configuration, and maintenance of the PDP-11/23-PLUS microcomputer system.

The manual covers both hardware and software aspects, including:

• Detailed descriptions of system components (e.g., KDF11-B microprocessor, MSV11-P memory, RLO2 disk drives).
• Instructions for initial system start-up, loading operating systems (like RSX-11M, RSTS/E, CTS-500), and basic control panel operations.
• Extensive diagnostic programs (DLDP+, DEC/X11) and troubleshooting procedures for hardware errors and system malfunctions.
• Guidelines and rules for system expansion (memory, mass storage, additional cabinets), including jumper configurations and component placement.
• Specifications for optional peripheral equipment (terminals, expander boxes) and environmental system requirements (power, cooling, cleanliness).

Essentially, it serves as a complete guide for setting up, running, maintaining, and expanding the PDP-11/23-PLUS system.
