Pdp-12 Instruction List Linc Mode

This document serves as a comprehensive technical reference and instruction list for the Digital Equipment Corporation PDP-12 computer, specifically covering operations in both LINC mode and 8-mode.

Summary of Contents:

• Character Set: Provides the mapping for External (ASCII) to Internal character codes.
• LINC Mode Instructions: Details instruction sets for ADD, MULTIPLY, LOAD, STORE, SHIFT/ROTATE, OPERATE, LOGICAL OPERATIONS, and SKIPS, including operation codes, class definitions, and execution times.
• System Operation: Includes startup procedures for LAP6-DIAL, as well as command references for PIP (Peripheral Interchange Program) input/output devices and control commands.
• Memory and Addressing: Outlines the memory organization for both LINC-mode and 8-mode, and provides rules for address computation (Beta class and half-word addressing).
• 8-Mode Instructions: Lists basic, operate (Group 1 and Group 2), and combined instructions, as well as specific command sets for peripheral hardware including RK8/RK01 disk cartridges, line printers (LP12/LP08), random access discs (DF32, RF/RS08), EAE (Extended Arithmetic Element), Real-Time Clocks (KW12 series), and Teletype/High-Speed Paper Tape input/output.
• Instruction Formats: Contains visual diagrams and bit-assignment tables for various instruction types to assist in machine-level programming.
