In some cases it should be possible to write a
machine code program
that executes on 2 processors with wildly different instruciton sets.
I have this bit set that I was told (or something, the memory is _very_
vague) that early versions of the KL-10 had this hack; the root block on the
disk was the boot block both the PDP-10 and the PDP-11 front end machine, and
the first instruction or two was very cleverly construced and sent the two
machines different ways. Alas, I looked in the front-end PDP-11 code (in the
KLDCP; directory) and saw no signs of this, so maybe it was an urban legend?
