3Dfx Voodoo3 PCI
A nice engineering sample! This is probably how the Voodoo3 PCI would like if 3dfx did not acquire STB.
The card has no Avenger chip installed and the PCB uses aluminium interconnects. I have another engineering sample which uses copper interconnects. This card would suffice using the aluminium because it would not feature a Nepenthe socket for swapping chips. Now I only wonder why the engineers at 3dfx never installed a graphics chip ... I guess they had PCB's fabricated in batches of 10 or 20 pieces each and didn't need that much of this particular batch/revision.
