Heya guys, I'm trying to find a compatible PCI card to add USB to an old PowerBook G3, family number M4753. I was just given this thing and I'm not even sure it works. I'm not having any trouble tracking down power adapters, but I've somehow managed to live my entire life without needing a PCI card and I'm a little lost. I just want USB so I can turn this thing into a Nintendo emulator. Any ideas? Thanks!
