This is pretty wild. Somebody at my office was throwing out an old power mac g4. Thankfully I stopped them and I was able to take it. Needless to say I'm thrilled. BUT - It has a problem (which is possibly why they were going to throw it out, I don't know).
When you hit the power switch, it just goes 'Beeeeeep' and you can hear the fans humming. To me that sounds like an error message. So I opened it up and sure enough, all of the RAM banks are totally empty!
So now I need to know what kind of RAM to put in there... and I have no idea which G4 this is. I think it's going to take SD RAM as the slots have 3 breaks (instead of 2 like DDR uses), but I don't know at what speed. It has a DVD-ROM drive, an IBM deskstar 20gig PATA hard drive, and an AGP slot of some kind. And on the hard drive is says 'Apple HDD Firmware 1999', which implies it's a first generation system as I think they first came out around then.
So what do you think this is, and what is causing that error? I'm used to PC's where a no ram error is a sequence of beeps, this is just one long beep.
And also, can I just buy any standard parallel interface hard drive and throw it in here? Or as the sticker says, does it have to be apple specific? I've never dealth with hard drive firmware before....Argh!
Anyway if I don't get many responses or if more info is needed I will try and take some pictures of it tomorrow and maybe that will help.
If it is an AGP slot G4 machine, then it will take PC100 or PC133 RAM up to 512 Mb. The 512 Mb module MUST be a 16-chip module. Although there is physical room for 2 Gb (4 x 512) but only the first 1.5 Gb will be recognized.
If it is the PCI-slot graphics first gen G4 machine ("Yikes" motherboard), then it will only take 256 Mb module, and that 256 Mb module needs to be a 16-chip module.
Also, you would be well to replace the PRAM battery for $10 or so. 1/2AA 3.6V Lithium.

I wonder if it has the airport card or not... It has this little riser card that says 'Hongkong Telecom' on it, no idea what that's for. And also those PCI slots are really long, I almost thought they were ISA slots! But the hard drive explanation is a little wierd, what does it mean by 3 36gb BTO? Is BTO Built To Order? So does that mean it tops out at 36gb hard drive? The ATA-66 interface is incredibly old so I don't really know, would it support a more modern ATA speed?
