Computer History Tracing the History of the Computer - 6502 Microprocessor
The 6502 is an 8-bit microprocessor that follows the memory oriented design philosophy of the Motorola 6800. Several engineers (led by Chuck Peddle) left Motorola and formed MOS Technology, which introduced the 6502 in 1975. The 6502 gained in popularity because of it's low price and became the heart of several early personal computers including the Apple II, Commodore 64, and Atari 400 and 800.
