"A DiskVaccuum For Obsolete Disk Formats"

Machines up to early G5s have PCI slots (PCI-X is directly compatible with PCI, though the card must be keyed for and compatible with 3.3v signaling; typically on a standard PCI card, this would mean two keying notches since very few PCI cards were produced for 3.3v only). Multicore G5s have PCI Express, which won't do. Pictures I see online of the Catweasel Mk4 show dual keying notches, which indicates that it SHOULD work fine in PCI-X slots. There are Thunderbolt-to-PCI conversion boxes, but my understanding is that they require some driver support (i.e., they don't work out of the box with the original PCI drivers without modification). Driver-wise, I would hope that it works well under 10.4, at least; that's the latest OS I ever feel comfortable with on PPC Macs, because 10.5 was such a dog even on G5s. The site doesn't say, but the kernel PCI interfaces didn't change a whole lot between 10.2 and 10.5, to my recollection. Those neurons are a bit dusty, though. - Dave
