Would anyone care to comment on the relative advantages and disadvantages of
the Motorola 88100/88200 and the Intel i860 for a shared memory
multiprocessor running MACH.  I would like to hear how well each processor
is suited to MACH and memory sharing within a MACH task; and what this means
for system performance.  I have my own prejudices on this matter, but I
would like to hear from people with some experience with either of these
chips and/or MACH.

	Thanks,

P.S.  I am not interested in starting a processor war.  I just would like to
hear comments to the effect of feature W on processor X is good/bad because
Y and might have Z effect on performance in such a system.  If you have had
some experience with both chips, I would also like to hear about it.
