  They are 80-pin SIMMs.  I have some of the 80-pin SGI SIMMs here; I
might be able to try them out...though I doubt they'll work; they have
two rows of DRAMs on one side and a huge surface-mount ASIC on the
other...not sure what it's for, but it doesn't look too good to me.

  Note, however, that those SGI simms are somewhat hard to find...if
they do work, I doubt it'd be much of an advantage for us...Those
SIMMs *only* work in the 4D/35 machines (the 4D/20 & 4D/25 use 30-pin
SIMMs), which are still almost fast enough to be useful.

  Your DS3100 memory will work in a 5000/1xx.  There are two kinds of
SIMMs...2mb and 8mb, I believe...I just bought about 170 of the 2mb
ones from a guy who advertised 'em on usenet, so they *can* be found
if one looks hard enough.  I'll be using mine in a stack of some 30
DS3100 machines I've got here which currently have no memory.
