How exactly does the G3 upgrade fit in with the HPV or AV card?
A. This is a picture of a Nubus card. The HPV and AV cards have similar (but not identical) form factors, so I can use this series to images to illustrate. Both the HPV and the AV card were actually designed for the 7100 and 8100 form factor. As such, they are supposed to plug in vertically, so that the card sits perpendicular to the floor.
