The big card is an impact vision 24, rev 5, which is designed for the 3000 - which has a video slot in line with zorro slot. The smaller card is for the 2000 only and I guess plugs into the video slot on the other side.
it acts as a frame grabber, frame buffer and should be able to perform as a limted RTG card if you can find the EGS drivers for it.
Nice piece of kit
