68000

A family of 32-bit microprocessors from Freescale Semiconductor, Austin, TX, www.freescale.com, a spin-off of Motorola in 2004. Motorola introduced the first 68000 CPU in 1980, and the series has been known as the "MC68000," "68K" and "680x0." The chips were used in various devices, including workstations, PBXs and the early Mac line, starting with the first Mac in 1984. The instruction set and other elements of the 68000 architecture continue in Freescale's 68K/ColdFire embedded processor line.
