How do you tell? System Profiler just says "G4 (2.0)" for my G4/733, and "G4 (2.8)" & "G4 (2.9)" for the G4/400s—no PPC model numbers there. All three systems are "charcoal" mini-towers. (For some reason the figures in parentheses are larger for the earlier models, unlike version numbers.)

Try Mactracker Link and go to your Mac models, it shows this numbers along with the PPC model numbers, might be the revisions of the CPU.
Somewhere i see a list of the various types of 680xx, G3 and G4 and there differences and enhancments over the time.
Different Question:
Which times are to expect on a old iMac G3 350 MHz (Summer 2000, MachineID PowerMac2,2) running OSX.3.9? Any improvements with OSX.4?

The OS version shouldn't make much of a difference; I'd expect crunching times to be rather slightly slower on OSX.4, because of background processes (Spotlight). This machine might be comparable to yours, it took 113004.48s CPU-time (maybe 32h wall-clock if you're lucky) for a result with the official App 4.39. The 4.56 should be about twice as fast on non-AltiVec machines.
That's why I asked everyone to go into Terminal. When you run machine, it returns the CPU variant. As far as Apple's marketing dept. and System Profiler are concerned, it's G3, G4, and G5. But to OS X's UNIX underpinnings and heritage, it's ppc7400, ppc7450, or ppc970 (possibly even ppc604 if you play your haxies right...)
BTW, MacTracker is an excellent app - has been for a long time.
As for Spotlight, the answer is that its affect on BOINC is negligible. The only apps that'll irk BOINC are highly CPU intensive ones (ex.: Final Cut, Maya).
I've just installed it on my PowerMac G5 1,8 Ghz Single FSB 600, running Panther 10.3.9.
Are the workunits available for the Beta Test only dummies or do they take part in the real scientific research ? If they should be only dummies, how much time should be spent with running the test application before returning to the regular version ?

The wus are real. The beta testing is mainly for compatibility and speed issues for that particular application.

This is intentional. The error message was a bug in the BOINC version we were using back then.

Bernd,
I've now had four WU's show invalid results using Albert 4.56 on PowerMac G5 Quad. Many others have been sucessful.
I'm also switching back to 4.39.
