The 68030 is a 32-bit microprocessor by Motorola, released in 1987 as successor of the 68020. It features on-chip instruction and data caches of 256 bytes each as well as an on-chip MMU. Available clock frequencies were 16, 20, 25, 33, 40, and 50 MHz. It has a three-stage pipeline, and an internal Harvard architecture with physically separate storage and buses for instructions and data. Like other 68000 family processors, the 68030 is a Big-endian machine.

General Purpose Computers

The 68030 was used in models of the Apple Macintosh II [2] and Commodore Amiga personal computers, NeXT Cube, and Sun Microsystems Sun-3/80 workstations [3].

Dedicated Chess Computers

The 68030 processor was used in several dedicated chess computers of the late 80s and early 90s, most notably in various top models of Fidelity Electronics, namely Chess Challenger, Elite and the experimental Fidelity X [4] with programs by Dan and Kathe Spracklen, and Hegener & Glaser's Mephisto brand with programs by Richard Lang, beside others the winning computers of the WMCCC 1989 in Portorož [5], the WMCCC 1990 in Lyon [6], and WMCCC 1991 in Vancouver (winner of the commercial group by default) [7].
