    Techworks 3DFX 8 MB Power 3D II PC PCI

    For Voodoo 1 and Voodoo 2, you can use generic driver and PC card. Fun think, you can even use a Voodoo with VirtualPC or RealPC and use the 3D acceleration. For Voodoo 3/4/5 (and Banshee), you must use a card with a Macintosh ROM, for the 2D parts.

    Airport cards that support WPA2?

    Technically, it's (perhaps) possible, but Apple don't do that. Even if you flash the card (or use a "compatible" card), the driver don't do that.  I suppose it's a little bit complicated to make a new driver to do that, and by the way, many Mac can use an AirPort Extreme (compatible) card.

    Airport cards that support WPA2?

    The first AirPort Card is a "subset" of PCMCIA. Actually, you can use an AirPort card into a PCMCIA slot, but not a classic card on the AirPort slot (i think Mac OS and Mac OS X just block that). And you can't use WPA2 with this sort of card. To have WPA2 on Mac with AirPort original slot, the...
