The Motorola 68008 is an 8/16/32-bit microprocessor made by Motorola. It is a version of the Motorola 68000 with an 8-bit external data bus, as well as a smaller address bus.The original 68000 (introduced in 1979) had a 24-bit address bus and a 16-bit data bus. These relatively large buses made it hard to design a low-cost system based on the 68000; they were difficult to lay out on a circuit board and needed a lot of supporting circuitry.
