I need some help. I just got this iMac G3 the other day and I'm going to give it to my mom but first I would like to update it as much as possible. Its got OS X 10.3.9 450 MHz and 128 MB Ram and a 20 gig HD. Can I put airport on this and also what is the maximum amount of ram that can be put in? I would like to do a fresh install of the OS because its got a password on it that no one seems to know what it is no can I do updates. I was wondering where I could find an OS disc to do a fresh instal or what OS can this baby handle so I can get the most up to date OS? Thanks for any info...
