I have a PowerMac 8600 with a Sonnet G3 400mhz upgrade and run a OS 8.6 for the system. The spec's listed for this processor say it is a 64bit processor but I don't think the OS is. The Apple site says the G5 is the first 64bit processor, so who do I believe?

A G3 Sonnet would be a 32 bit processor G3-750. Your memory performance might be 64-bit, that's moving memory or that's measured in MB/sec to copy memory from one location to another, flushing writes out of all caches.
I got the info from Gauge Pro.

And MacOS 8.6 is not a 64-bit OS either.
It's rumored that a G5-upgrade card for PowerMac G4 MDD computers might be announced at MWSF '04.

I got a good reply at everymac, but the answer is consistent with the ones here. Thanks for the info and clearing up the haze I was in and sending me a new quest to learn more about the powerpc.
