Go into the Mac forums on the apple website. It's not as uncommon as most people think. They are still a lot more stable thsan a pc. I never had the power pc mac, just the intel. Could that possibly have something to do with it?
Come to think of it, I have an old hp 386 laptop running 3.1/dos5. Still works. I was surfing the net with that machine before most people ever knew anything about it. That was in the days when computers were fun.
