PDP-11 Programming Card

This document is a concise, two-sided quick-reference card for the Digital Equipment Corporation PDP-11 computer family. It provides comprehensive technical data necessary for programming at the machine level, including:

• Addressing Modes: Detailed explanations for register, deferred, auto-increment/decrement, and index addressing.
• Instruction Sets: A numerical list of operation codes (opcodes) and mnemonics for the CPU, covering single-operand, double-operand, branch, and trap instructions.
• Floating Point Processor: Specific data for the PDP-11/45 and 11/70 floating-point processors, as well as the PDP-11/35 and 11/40 floating-point units.
• System Details: Information on processor status words, condition codes, trap vectors, register addresses, and miscellaneous operations.

This card serves as an essential manual for programmers working with PDP-11 architecture in the mid-1970s.
