some clones had a ZIF slot, but I'd never heard that upgrades had been made for it, thats all.

That's how UMAX got around Apple's refusal to certify PowerPC 750-based clones: they made upgrade-capable computers, sold them either with an older 603/604 or no processor at all, and threw a G3 upgrade card in with the package. That way they were selling already-certified hardware with a separately-boxed user-installable upgrade as a package deal.

If Apple can use a loophole to force the clone vendors to renegotiate the Mac OS licensing scheme, then UMAX can use another loophole to sell G3-based computers without having Apple certify them as such.

I wonder if you can run OS X on them :?: :?: :?:

I got OS X 10.1 running on the PowerBase that I had (i forgot the speed) and it was based on the 6400 machines. Although the sound didn't work. I also remember that it didn't work with the L2 cache G3 upgrades because of the way the video was done. I *DO* know you can pop an upgrade from a 604 machine (Card 604) into it and any upgrades for that. I didn't get to keep it, but I got to borrow a 400Mhz G4 upgrade and a 604 from an 8600 (the G4 was for it too)
