Pdp-12 Memory Organization

This document provides a technical reference table for the PDP-12 computer system. It lists the assembly language mnemonics, corresponding machine codes, function descriptions, and execution timing (in microseconds) for various operations, categorized into four groups:

• Operate: Basic control instructions (e.g., halt, no-operation, jump).
• Logical Operations: Bitwise logic functions (AND, OR, XOR, complement).
• Skip: Conditional branching instructions based on register states, switches, flags, or external conditions.
• Input-Output: Commands for managing data transfers, analog sampling, display output, and mode switching.

Additionally, the document includes a visual diagram and brief notes describing the memory organization for both "LINC-mode" and "PDP-8 mode," noting specific memory addressing, field capacities, and interrupt vector locations.
