Hello everyone, this is my 1st post here but been checking up on this site for some time now. Seems like you guys know what you're talking about on here so maybe someone can help me out. I have 2 iMac at home, a White 24in 2.16 Intel, and an old iMac G3 500 DV. I do all my regular stuff on the newer iMac and really only use my G3 for backing up some of my own DVDs and letting my daughter get on the web and check emails, nothing more than just that. It's running OSX 10.1.3 I believe, with 512 memory and a 30gb hard drive, dvd drive but no write just plays dvds. I have an external dvd burner connected through the firewire port. What I want to do is know how can I max it out, more memory, bigger hard drive and update to the lastest OS possible that can run on this G3. But at a low cost where ever it's possible. 1st what's the most memory I can upgrade this unit to? Where can I buy and what's a good deal to buy at. 2nd same for the internal hard drive, can I do this myself? What kind of hard drive does it use and can this even be done. 3rd OS upgrade, if I update the hardware in the G3 can I upgrade to OS 10.5 or where would it top out at? 4th The clock always resets itself after every shutdown, is this because of the little battery inside that needs to be replaced and if so can I do it myself and where can I buy the right one. If anyone can chime in with anything useful information thanks in advance.
