Some guy said it's Quad-SLI, but it looks too much like Quad-TV card to me! Haha!

Maybe it's an early version??

Nope the top port is a composite out, looks like old Graphics cards to me. Probably a Voodoo Quad SLi attempt, they did use the SLi attemp and did have some monster sized cards. Also note that the pin arrangement looks like PCI, which would match the Voodoo theory. Unfortunately Voodoo FX went bust soon after they started doing SLi.

Fun fact - Voodoo's SLi is short for "Scan Line interleaving", after how the image was produced, where each card would do an alternate line on the screen. nVidia liked the name and used it for their "Scalable Link interface", which also represents the image production, where the nVidia cards split the screen dynamically dependant on load.

I pwn!

They were right with the scalable thing too... Well, they could be if Quad-SLI actually worked.

Yeah, but I think the scalable mainly refers to the dynamic scaling of screen division.

I think it might mean because it's extensible. Maybe.

Probably both.
