Okay, I am a teacher and I have 5 computers in my classroom. 2 Gateway Pentium Pro 200's, 1 Gateway Celeron 550, a PowerMac 6100/66 and my personal iBook 600 which I keep at my desk. Of course the kids love my iBook, but since I bought it with my own money...I don't let them use it much. I do love OSX 10.2.2, it works so nice on the Windows network, even better then my Win98 machines do. Anyhow enough history, my question is about the old PowerMac 6100/66. The school was throwing them out when they updated the last lab to PC's so I decided to grab it for another computer in the classroom. It runs well and I have loaded some fun games on it that the students love, but the OS is in poor shape and there is a lot of "broken" things on it. I have also had problems getting it on the ethernet, although my tech coordinator says it should work on the internet, if all the addresses are entered right on it. I am running system 7.5.5 on this machine. What would be a good version to move up to? I see where the machine is supported up to 9.1, but I am afraid the HD is too small for system 9 and Office 98, games, etc. Is there anyway to purchase a newer copy of Mac OS and what system would work well for a 6100/66. All the old system restore stuff has been thrown out. How much disk space would OS9 take compared to the current 7.5.5? Any help would be appreciated. I would like to get a couple more years out of the old girl for games and work processing.
