A series of CPUs made by Motorola.

Introduced by Motorola in September 1979, this is the first in the 680x0 series. It has 16 32-bit registers, split into 8 data and 8 address. Addressing was done in 32-bits, though the address bus was only 24-bits (later models expanded it to the full 32-bits). Instructions are multiples of 16-bits and all addresses have to be 16-bit aligned (except for addressing single bytes, of course).

The 68000? was used in the AppleLisa and AppleMacintosh as well as the AtariST, SegaMegadrive? and some Sun? workstations. The 68000 was succeeded by the 68010 in 1982 which allowed the use of virtual memory and fixed a bug where the address of where a memory exception occured was incorrect. The 68k was used up until recently in PalmPilot PDA's
