Three Intel 8080 8-Bit Contemporaries - Moore's Law In Pictures
Launched in 1976 by former Intel employees, Zilog’s Z80 was binary compatible with the 8080 and featured many improvements over its predecessor, including a more efficient power supply and a built-in DRAM refresh feature. The Motorola 6800, available in 1974, became popular for its wide array of supported hardware. MOS Technology’s 6502 and 6510 chips were simple and affordable when they started showing up in 1975. Western Design Center’s CMOS 65C02 was an upgraded version of the MOS 6502. This generation of microprocessors contributed directly to the home computer revolution: just look inside the Sinclair ZX-81, the Commodore 64, Atari 2600, and Apple I/II/IIe.
