Maybe you forgot to enhale, there aren't more than a handfull of different
instructions between the pairs I mention. I haven't programmed the Sparc,
but I did spend about two weeks testing the feasibility of porting a 65C02
assembly language program to the Sparc, and it looked very very good. As
for the 360/68k, IBM made a varient of the 68k that ran 360 code native.

Wow this sure is sounding like a bunch of old coots isn't it? ;)
