The MOS 6502 is an 8-bit microprocessor designed by Chuck Peddle and a team of engineers at MOS Technology and released in 1975. The processor was one of the most popular chips for home computers and video games from the late 1970s through the 1980s and is still used in embedded systems to this day.
I didn't start learning about the 6502 until after I began playing with the debugger of a NES emulator. There, I began teaching myself about 6502 machine language. I'm still quite terrible at it, but I known enough to read and modify basic programs.
Contents
Devices
There are a couple dozen devices which use the 6502 and its variants, but here are the most popular ones:
- Acorn Atom
- Acorn Electron
- Atari 2600
- Atari 8-bit family
- Atari Lynx
- Apple
- Apple II family
- BBC Micro
- Famicom
- Commodore PET

- Commodore 128
- Commodore Plus/4
- Nintendo Entertainment System
- PlayChoice-10
- TurboGrafx-16
- VS. System
A 16-bit version of the 6502 was created in 1983 and variations were used in the Apple IIGS and Super Nintendo Entertainment System.
