This is really two questions but here goes: First - how do you think OS 10.2.2 then upgraded to 10.2.8 would run on a Power Mac G3 with 256b megs of ram? I believe it meets the requirements but I wanted to know of any actual experience with that.
Second - this may show my ignorance but here goes - I have a 10.2.2 CD - it was purchased - I have installed it on a machine and upgraded to 10.2.8 - works fine. I have about 6 other machines running 9.2.2 - If I want to upgrade do I need to or should I purchase additional copies? Will it work if I don't? I realize there may be a legality and ethical issue here...but in all honesty I really don't know.
