The IEEE-696 S-100 bus standard does allow for 16-bit data paths and 24-bit
addresses (16M).

While I don't have much experience with the Multibus, I have heard just
the reverse -- that the Multibus is faster than the S-100, but I'm not sure
why.  From looking at S-100 bus lines on a scope, I've seen a lot of
cross talk occurring, and some of the resultant spikes dip very close
to the active region (3.5V).  Some S-100 motherboards are shielded better
than others, providing less cross talk and (I suppose) greater speed.
I am running S-100 at 4MHz, and the best that I've heard of is 6MHz
(or was it 8?).
