Yea, I looked at the about my Mac button and it says its a iMac PowerPC G3 500mhz and 256 mb of rams and a 76.3gb hard drive. (i'm pretty sure the previous owner upgraded everything)
Dammit I sold my Tiger disks from my sister's iBook G4 for $100 and forgot to make a copy of it....plus the iMac doesn't have a dvd drive anyways...
I might just have to find a way to download Tiger again...
All this just for iPhoto for mom, lol. Perhaps there are some alternatives to iPhoto that can run on this machine.
