    There was also a 4MHz version.  I had one in my MEX68KECB but I'm not
    sure if they were ever sold separately.  ISTR I got the impression
    that it was a different (early) mask or microcode variant because some
    of the interface timings weren't consistent with the 8/10 MHz versions
    (something like one of the bus timings was a clock-cycle slower).

    I also really liked the M68k architecture.  Unfortunately, as with the
    M6800, Motorola lost out to Intel's inferior excuse for an architecture.
    
    Moving more off-topic, M68k got RISC-ified as the ColdFire MCF5206.
    That seemed (to me) to combine the feel of the M68k with the
    clock/power gains from RISC.  Unfortunately, it didn't take off.
