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. The 6502 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 can make simple changes to existing code.
Contents
Devices
There are about a couple dozen devices which use the 6502, but here are the most popular ones:
- Acorn Atom
- Acorn Electron
- Atari 2600
