Actually....you can do that.
The IBM {PC,XT,AT}/370 card(s) (ISA-bus card that put a "baby" IBM S/370 on
your desktop) had a CPU that was a re-microcoded 68000 (emulating some
subset of the IBM S/370 mainframe instruction set). IBM licensed the
architecture from Motorola. Probably got familiar with it building the IBM
9000 Instruments System.
Interesting. I knew about the 370 card sets; didn't know they were descended
from the 68000. I did work with an IBM 9000 at GE
once... really slow, and
the language of choice was Pascal. :-P (fortunately for
me, 99% of my work
was on the 11/73 next to it (I was writing a Computer-Aided Instruction
course in MACRO-11 under RT-11/TSX-11)).
