I was given a blue & white G3 tower (revision A from the first week they were on the market). It boots. I haven't checked how much RAM is in it, or how big the drive is that came with it, but these are easy to upgrade. Anyway, what I am wondering is the following... What is the highest version of OS X that it can reasonably run? What is the maximum amount of RAM it can take? What creative uses can I put this thing to work doing? My IP to the outside world is dynamically assigned by my ISP, so I can't see this acting as a server to the outside world in any sort of practical way. I have an 8MB connection with an uplink of about 384Mb. I already have a wireless network drive and wireless stand-alone laser. Currently I run an Intel iMac and MacBook at home. Given the noise this thing generates, if I do find a use for it, it can preferably be kept in a closet. I really think this is a beautiful machine. The side door is absolutely brilliant. Is there any way to easily and inexpensively upgrade the system board or processor? Surely somebody out there has found an interesting and useful application for these machines with a home network. Any and all ideas invited.
