Nothing special... just a regular PCI.... not PCI-Express...doesn't need to be high performance or anything...
I know... Been through all of my stuff and some friends offered up their old pc's for parts....nothing panned out...lol...
If not, I may have a dear old TNT2m64 around somewhere. That's one of those old cards that I just didn't have the heart to shit-can.
I think I got it covered now... had a friend with one and he wasn't sure if it worked...took it home and got it running...seems good so far...
