The 68000 was the first member of Motorola's m68k processor family. The CISC (complex instruction set computing) design found use primarily in workstations including systems such as Sun's Sun-1 and Silicon Graphics' Iris 1000, typically running at 10 MHz as well as Sun's 150U server, laying the foundation for Sun as a server company. Succeeding models became rivals of x86 processors and were, for example, used in Apple's Macintosh and Commodore's Amiga systems. The m68k is still used in derivative designs in embedded designs today. Sun continued to use the processor, especially the 68010 and 68020 for its Sun-2 and Sun-3 servers in 12.5 MHz to 33 MHz versions.
