Should work with any PCI Powermac. I have the later XClaimVR 128 in my beige G3. Think of it as the Macintosh version of ATI's All-in-Wonder card. A TV tuner (ATI XClaim TV) was an optional outboard box on these models.
geeze to think I had been wondering about finding a non-128 vr card. but anyhow ironborn njroadfan answered your question or to be more precise the old ati.com site passphrases "pci power macintosh, version 7.5.5 or higher, quicktime 2.5 or higher"
