WOW !!!
I was cleaning my old hardware mess, looking to trash some old reliques (ex. a BNC ETH ISA card) and found 2 oversized PCI video cards linked together with a 34 pin bus...
Yes, you guessed... 3Dfx - Creative Labs CT6670 Voodoo2.
I was wandering if there existed some support for those aged cards so I googled for them and  found your site.
I can't believe there's so many people still enjoying them and developing drivers for XP, MacOS & Linux.
Bet for it, I will install them on an old Pentium II WinXP I run on a 16MB ATI.
THANKS !!!
