The MOS Technology 6502 is an 8-bit microprocessor developed by MOS Technology in 1975. When It was introduced it was highly praised for its cost and is still being produced to this day as the 65C02 by the Western Design Center (WDC).
Many popular home video games consoles and computers such as the Atari 2600, Atari XL, BBC Micro, Commodore 64, Nintendo Entertainment System and other systems have used the 6502 and variants of it as its main processor.
