This has been used as the base processor in several Amigas and on several accelerator cards. The MC version is a later revision of the 040 which is more tolerant to heat and overclocking than the XC version. Unlike other processors in the 68000 series, the 68040 actually halves the clock speed it receives. For example, a 25Mhz 040 requires a 50Mhz clock and a 40Mhz 040 requires an 80Mhz clock.
