Hello, We recently were given an old G3 that used used in a local school system. Though grateful. As our G4 died a horrid death after many months of suffering (it's and ours) this G3 is odd. It is running 8.6 and yet the system is not quite what I am familiar with. I'm not a Mac expert but I have owned them since the system 7 days and I thought I knew my way around the system pretty well. My questions are .. 1.Is anyone familiar with operating systems set up for school use? 2. Can I reformat this Power Macintosg G3 all in one and put in a different OS? I have OS9 and OS 8.5 on CD's. But I don't know if this machine will allow me to jump up one or down one OS. It tried to use Tech Tool Pro 3 and got just a little confused. Thanks in advance for any help anyone can give.
