I may have one of those cables around i know i have the card,, but my understanding of the cable was it was used to link 2 voodoo 2 cards together not a voodoo to a standard video card. Mine came with and piggyback cable that goes outside the case to connect the voodoo to the standard card. So you would need a standad card, and 2 voodoo 2s and the internal cable i believe. I could be wrong im off to find the cable to check now.
I found mine the connector on the internal cable is the same end a floppy cable uses its about 2 inched long and both ends are the same, but there are 4 cables flipped in the middle so a floppy cable wont work right i doubt it looks like 7 wires are flipped in the floppy cable i have here, sure u could rewire one though if your patient.
Zedric, I don't quiet understand though I realise that a floppy cable is similar as I looked at that Idea. How would I make my own connection with a Floppy cable, I don't quiet understand all this and I wan't SLI mode because I've tried outside cable mode and that doesn't use the other card. Just leaves that to 2d rendering.
