There was also a Power Computing version of the HPV card which had the same 2/4 MB configuration as the Apple 8100 card, but also has a VGA connector in addition to the Mac DB15 connector, and a little switch on the board for switching between the two connectors.
The nicest thing about the PCC HPV card, in my opinion, is that if you see an HPV card with two video connectors on the back you immediately know that it is the PCC version and therefore you know that it is a 2/4 MB card without having to puzzle out the amount of VRAM on board.
I totally agree with Tyler about bandwidth and the HPV card.
The internal only SCSI bus in the 8100 is meant to be Fast SCSI, 10 MB/s. Whether the performance supports that, I cannot say. However, the chip used is the 53CF96 and Apple's Developer Notes for the 8100 claims that it's 10 MB/s.
