It's all accelerators and video cards out of 7100/80AVs, so they are all PDS slot cards. There's also 2 accelerators for the 6100... they are the PDS type with a right angle PDS slot above the heatsink. I think they are both 150MHz? cards.

As for the oddball keys on the Keyboard II, I'll get a better picture of them.

By the way.... The guy I got this stuff from worked for the US Government, and he got all of this stuff at government auctions. He also had TONS of Sun stuff, as well as a few PCs.
