The original assembly source code for Microsoft BASIC Version 1.1 for the 6502 microprocessor, released under MIT license. It is a historically significant 1976-1978 interpreter that powered early personal computers like the Apple II, Commodore PET, OSI, and KIM-1.
Use cases
- study the source code of Microsoft's early BASIC interpreter
- build a BASIC interpreter for a 6502-based retro computer
- run BASIC on an Apple II or Commodore PET emulator
- learn 6502 assembly from a real historical codebase
- port a vintage BASIC interpreter to a homebrew 6502 system
- research the history of early personal computer software
When to choose
- you want authentic, historically significant 6502 assembly source code
- you are building or emulating a vintage 6502 machine and need a BASIC ROM
- you are teaching or learning assembly language and interpreter design
When to avoid
- you need a modern BASIC interpreter with contemporary features
- you want a maintained, production-ready programming language implementation
- you are not comfortable reading 6502 assembly with conditional compilation for 1970s hardware
