Dec Opcodes – DEC Architecture Reference
Before the microprocessor, there was DEC. The minicomputers built by Digital Equipment Corporation didn't just advance computing - they defined it. Unix was born on a PDP-7. Spacewar! ran on a PDP-1. The field of Artificial Intelligence was born on the PDP-10. The VAX powered universities and research labs worldwide for a generation.
DecOpcodes puts the complete instruction sets of these legendary machines in your pocket.
Five iconic architectures covered: PDP-1 (1960) · PDP-8 (1965) · PDP-10 (1966) · PDP-11 (1970) · VAX (1977)
For every instruction:
• Full description of what the instruction does
• Octal and hex encoding
• Flags affected
• Addressing modes, word count, and cycle counts
• Assembly code examples and implementation notes
But there is a lot more than just dry opcodes:
• Complete system specifications and register architecture
• Historical context and cultural impact
• Archival photographs - front panels, system cabinets, and more
• Notable installations and the systems they powered
• Architecture variants and successors
• Interactive lessons on assembly language and console operations (ideal if you have an emulator)
Built for exploration:
• Search across all systems instantly
• A simple assembler for PDP-1, -8 and -11 code
• Filter by instruction category
• Sort alphabetically or by category
• Favorite instructions for quick reference
Beautifully designed:
• System-specific accent colours
• Five themes including Terminal green and Blinkenlights orange
• Full Dark Mode support
From the 18-bit simplicity of the PDP-1 to the 32-bit sophistication of the VAX, DecOpcodes is a fascinating and interactive journey through the machines that made modern computing possible.

Hello DEC fans! In this update, I added a Glossary, so you can stop dropping DEC-terms into casual conversation. I also updated the PiDP-1 and PiDP-8 sections with some more useful little facts and tips.
