I have a interesting question that I would like to see answered.  We have an
IBM AT with expansion memory here that has an expansion board for it that
(again IBM's) that uses SIMMS.  Does anyone know if these SIMMS are compatible
with the Mac II.  I realize the speed requirement (120ns) and I can check that
by the part number (hopefully on the SIMMS).  The real question is of course
is the 'pin out' on the SIMMS the same between the two.  I am sure that they
are 256K density SIMMS with 9 bits wide /SIMM.  I also realize that the Mac II
does not use a parity bit.  Would that extra bit just be ignored on the Mac II
or (more likely) are the parts (Mac II SIMM) and (IBM SIMM) just totally 
incompatible.  It just seems sad to use a megabyte RAM disk on the IBM (lots of
SIMMS going to waste!).
