2 Indy's, both with 4600s I think (large heatsinks denotes a 133mhz 4600?), an unknown graphics card, I think. Can anyone confirm or deny? Indy's take regular 72 pin Simms with parity?

All my SGI stuff is for sale incidentally. 1 Indy's case is a bit smashed. I also have an Indigo 2 Impact 10000 sans drop down cover and optical drive/sled. Indy's have no drives at all (hopefully I have parity memory). The Indigo 2 has 2 x 2 gig drives, but are wiped (had Irix 6.2) as they were used by the gubmint.
