I have two cards that have eight of these on each one. A quick search
<http://www.google.com/search?hl=en&q=ibm+memory+FRU+70f9973&btnG=Google+Sea
rch> shows that the SIMMs are used on the Artic 960 card and one some IBM
RS 6000s. These are parity SIMMs and look like regular PC SIMMs except
that the notch in the bottom corner is much shorter therefore these won't
fit some/all(?) PCs.
Trade for ???
