Programmed Data Processor-5 Handbook

This document is the official handbook for the Digital Equipment Corporation's PDP-5, a high-speed, general-purpose, 12-bit digital computer. Published in 1964, the manual provides comprehensive information on the system's architecture, including its arithmetic and control unit, core memory, and input-output capabilities.

Key sections of the handbook include:

• System Overview: Details on processing speed, memory addressing, and general functional components.
• Arithmetic and Control: Descriptions of registers (Accumulator, Program Counter, etc.) and instruction sets, including memory reference and augmented instructions.
• Input-Output Control: Explanations of how the system manages communications with peripherals via device selectors, programmed interrupts, and data break facilities.
• Peripheral Devices: Operational guides for various optional equipment, such as Teletype terminals, high-speed tape readers/punches, card equipment, and magnetic tape controllers.
• Electrical Interfaces: Technical specifications for cabling and connecting external hardware to the computer's interface panel.
• Appendices: Quick-reference tables for instruction lists, character codes, and diagnostic/loader sequences for paper tape.

The manual serves as a technical reference guide for programming and operating the PDP-5, emphasizing that it does not serve as a tutorial for general programming techniques.
