Quite an engineering sample! This is probably how the Voodoo3 PCI would like if 3dfx did not acquire STB.
The board has no Avenger chip installed and the PCB uses aluminium interconnects. I have another engineering sample which uses copper interconnects. This board 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 ...
