I just picked up a pair of these very neat old graphics boards.

Alas I have no idea what they are or if there is hope of using them. One is
a dual
slot 9U VME board that has gobs of video ram all over it, including a board
labeled Z buffer.

The only output are (3) BNC connectors
(R,G, and B) and a 50 pin connector marked P4.

The other is a single slot 9UVME board with (8) 30 pin SIMM slots with 1mb
SIMM in them, a couple of Weitek chips, another 50 pin connector labeled
P4, jumpered with a baby backplane to the other board, and 6 led on the

Anyone know what these are and where to get drivers? They appear to be Sun
3 era, and the boards are labeled bSun OHCb with a megatek sticker.

They do not appear to work out-of-box in my 3/260 as console devices.
