If it also has four SIMM sockets on it then it is a PDS High
Performance Video (HPV) card for the PowerMac 6100, 7100 and 8100. It
will also work in the Power Computing Power 80/100/120 and the Radius
81/110 and the Apple PowerMac 9150.
In all cases it installs in the PDS slot.
There were two versions (three if you count Power Computing's
version). One has 1 MB of VRAM on board and is expandable to 2 MB by
installing four 256KB VRAM SIMMs in the sockets. The second has 2 MB
of VRAM on board and is expandable to 4 MB by installing four 512KB
VRAM SIMMs in the sockets.
The Power Computing version has both a Mac DB15 video connector and a
VGA HD15 video connector and a small switch on the board used to
select which output is being used. AFAICT, all of the Power
Computing HPV cards are the 2/4 MB version.
