My folks have my old Supermac c500/200, and it's always served them well. However, the 1mb of vram is a killer. I'd like to get them a cheapo PCI video card, with at least 4mb of vram, so they can get more than 256 color on their 17" monitor. I've found several 4mb ATi 3D Charger PCI cards for around $24, and was thinking that would fit the bill well. Would this card even work on a Mac? They have Mac OS 8.6 installed, along with whatever universal ATi drivers that came with the OS.
