The 6502, developed by MOS Technology, is an 8-bit microprocessor that was in common use as a microcomputer and video-game CPU from the late 1970s through to the early 1990s, notably powering products from Commodore, Apple, Atari, Acorn and Nintendo.
The 6502, developed by MOS Technology (later CSG, Commodore Semiconductor Group) and subsequently licensed to Rockwell and Synertek, is an 8-bit microprocessor with a 16-bit address bus that was in common use as a microcomputer CPU from the late 1970s through to the early 1990s. Typical clock speed implementations drove the CPU at either 1MHz or 2MHz, though the device was not locked to these speeds and could be over/under-clocked to a degree.
Commodore, Apple, Atari, Acorn and Nintendo notably featured the device in numerous microcomputers and video-game consoles during that time. Variant models include the 6507 and 6510, whilst later revisions include the 65C02 and 65C816. These models either lacked some functionality (6507) or enhanced the original design.
