9600 G4

[mac2geezer]

Picked up a 9600 G4/800 today, 512 MB Ram, a 4 GB SCSI drive and a 10 GB IDE drive driven off an IDE/USB/Firewire card. Radeon 7000 Video card and the usual floppy and CD drives. Case is a little rough in a couple of spots but not too bad.

When I first tried to power it up the PS would only click and the PS fan would make a feeble attempt to run. Thought I had been screwed with a DOA, but after some head scratching I replaced the Pram battery on a whim and viola, it fired right up. My impression was that the IIfx was the only Mac that required a good Pram battery to start up, but another bit of useful info.

None of the four Ram sticks have markings that match anything I can find, so don't know if they're EDO or FPM.

Interestingly, Apple System Profiler says the G4 is a 450 but TattleTech says it's an 800...which is correct?

Yeah, I am hoping that is the case with my Power Mac 9500 which was given to me by fellow 68kmla'er wthww. I have not gotten to try a new battery in it yet.

When I put the 1ghz G4 in my 7500 it wouldn't power up at first. It's a good thing I got an instruction manual because in the manual it says when you remove the old CPU you have to do a PRAM reset BEFORE you install the upgrade or else it won't work. When I put the G3 in my 7600 it powered right up, though. Maybe it's something you only have to do with G4's?

As I suspected, the G4 (Sonnet Crescendo G4 800/1M) was only running at 450MHz, but after running the Sonnet enabler scrounged from another machine it now runs at 800. Much nicer, and now ASP reports 800MHz; TattleTech seems to lie about processor speeds.

Mine reports unknown processor at 1000mhz. :lol:
