They also only supported integer multiply in a funky way:  if the exponent
field was 0, it did an integer 48-bit multiply.  Used the same unit as the
fp mult, of course.

Well, actually, the 88000 (and the i860, and the Cray's) don't have divide.
They have reciporcate (actually, I belive they call it reciporocal
approximation, and, at least on the i860, you have to go through a couple of
iterations to get the "perfect" result).
