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.
