The 4D20 and 4D25 used standard pc-type simms (w/parity),
the 4D/30, 4D/35 and R3K Indigo used an SGI proprietary
simm, identifiable by the large interleave controller chip
on one side of the simm. Did someone already mention that
you can only have 1 bank of 4Mb simms in a system, due to
a prom bug? There is no restriction on the number of other size
simms.
