Dual Beige G3?

that, and apple's distributed computing. That is really the only way. Besides, i don't think that the G3's were Dual Processor capable, which is probably why apple hadn't done it. Try throwing a Dual G4 Card in it. (Or whatever the processor upgrade path is.) I am not sure if that can be done either. In short, the answer would be "no."

I remember reading somewhere that the G3 archetecture lacks the support for dual processors, so it won't work. That's why Apple didn't release a dual G3 Power Mac.

Powerlogix or Sonnet or someone did briefly release a dual G4 upgrade for those machines, but it was taken off the market for some reason. There used to be a review of it on lowendmac.com, might still be, under mac specs>G3 desktop

I believe it was XLR8, or is that just Daystar, that had a dual ZIF upgrade for G3s. The G4s that you put in there didn't even have to be the same clock speed. Sadly, the upgrade wasn't supported in OS X.

I'm brand new to the forum here, but have been hacking macs, including the Beige G3 I am using to post this, for many years. It was indeed XLR8 that made the MP upgrade for ZIF-based macs. The card was called "velocity MP" They release 50, 66, and 100Mhz bus versions. They discontinued them due to reported hard drive corruption issues they supposedly caused. This also put them out of business, and Daystar bought out what was left of them. Having said that, I've been running an XLR8 Dual G4/533 setup in my beige for over a year now without trouble. (covering or unsoldering the floppy connector from the mobo is a must) Sadly, it does not seem to be supported under OS X, though one press release from the late XLR8 said a version of their Machspeed control software for X did support MP. The cards do allow assymetrical multiprocessing, too. The only real downer is that I cant seem to go any faster that 66Mhz bus speed using the MP card (I've tried two different G3 mobos). Also, the card requires "MPe" (multiprocessing-enabled) ZIFs from XLR8 to work. These can be identified by the yellow, rather than white, silkscreening on the ZIF card. The Dual G4 setup also seems to get into "cache-thrashing" at times, causing a temporary hang. Behaves well with A/V apps, though. The machine only really complains when running 4 or more windows in MIE under classic. That probably has more to do with the sorry-ass built-in video anyway. BTW, if you run dual G4s and boot into 10.2.8, it will just ignore the second proc. I do have a second Velocity card I might part with if there is interest.
