Thanks, Mike.
So I tried OF at startup and got these lines:
bad Bus Info CRC-16
Apple PowerMac8, 2 5.2.5f1 BootROM built on 04/06/05 at 12:46:02
etc.
Now, I assume the first line is a hint that I have a "bad Bus"
somewhere (cpu data bus?).
Would the Genius Bar (with an appointment) be able to do any
hardware diagnostics?

Mike, I'll try the D feature on the CD _if_ I can ever get it to

Tiger DVD have the same feature?
I do not think so. Each system's diagnostic tool is tightly
coupled to that hardware. I've never had any success using
anything other than the install/restore disks originally supplied.
You might be able to take the machine to a Genius Bar (with an
appointment) and they might have the right disks.
Can I do anything in the Open Firmware screen to do testing?
This is just my understanding. I have no authoritative data here...
Not of the sort that the diagnostic tools do. There quite a bit of
OF/EFI code being pulled from the disks in those cases that's not
present in the boot FLASH. (The disks supply more than just a UI
to run the tests.)
