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. 

That, of course, doesn't mean you could do it on a PALM.
