The 65xx family of computer processors have 8- and 16-bit architectures, use low power, and are used in high volumes, mostly in embedded systems. The line began with the 6501, and 6502, which were designed mostly by the same engineering team that did the Motorola 6800. They quit Motorola unitedly, and quickly designed new devices that competed with the Motorola 6800, and Intel 8008 and 8080, but cost far less. The 6502 powered many early video games, and personal computers, PCs: Apple I, II (not IIgs), III; Atari 400, 800; Commodore PET, 64, 128D; Acorn Microcomputer; Franklin ACE 1200.
