OK, my curiousity is piqued.
What is the HC in MC68HC000 chips? The one I have is on a DEC RF31
disk drive controller.

I'm not sure of the other details, but "EC" = "Embedded Control",
as you
say. According to my Motorola cribsheet, it's a 68020 with only 24-bit
addressing, without the dynamic bus sizing, ands restricted speed range.
It does have the co-pro interface, though, and probably most if not all of
the instruction set (the crib sheet doesn't get very detailed).

An A1200 question: what's the difference between the 68020 and 68EC020?
I believe the 'EC' version is for Embedded Control, and lacks some of the
functions of the plain 68020 (probably MMU-related or something).
