Hello everyone,
Have been talking to a very nice person who is willing to sell me a Formac Carrier Card at an extremely reasonable price. I also have access to a free 233 mh Zif from a Beige G3 PowerMac. I would like to use both the Formac carrier card and the 233 zif to upgrade a PowerMac 7300. My concern is this: Is the Formac Card compatible with Stock Apple zifs from a beige G3? I went to Formac's web site, and wasn't able to find any definitive information. I also called up Formac, and tech support wasn't currenlty available, but the salesman wasn't sure how it would work, but he leaned towards it not working.
Has anyone here tried this combination with success? Any pertinant information you think I should know before I purchase the formac carrier card?
Thanks for your help,
Walker

I have just bought a OWC ZIF card and they stated on the paper that it would run in Apple Beige systems as well as Formac ZIF cards.
I havent tried it then, but i would also assume it myself. Since processor modules are sometimes manufactured by Motorola themsevles (or at least not all ZIF sockets are the resellers brand).
If the ZIP on the ZIF card from Formac doenst show some formac reading on the board itself but rather some number code with thge text MOT in it somewhere, its a Motorola ZIF card. The it fits for sure.

I don't think the G3 chip is multiproccessor capable. Got to their website and lookup the specs.

I don't think we are talking about Multiprocessors here. Just a Zif-Daughtercard converter to go in a 7300. I'd imagine it would work fine, because all the zif pinouts have to be the same.

no G3's are Multi processor compatable, because of the memory controler.

Bottom line is, it should work. Don't know what adjustments are on the Formac card, but you should be able to get a little more out of the G3 by playing with your bus speed. I put an XLR8 card in my 8500 and by getting the bus up to 56.8 MHz I squeezed 454 out of a 400 chip. I thought it was pretty fast, until I got a DP 500.
G3's can be parallelled, somebody makes PCI cards with multi G3's on 'em, but it's not practical, the chip is not a "team player" like the G4 is. IBM uses PPC chips in their servers. I remember seeing one a year or two ago, pre-G4, that still used 604e's... 12-350 MHz 604e's. Yikes
