I was at my parents over the weekend and decided to reclaim my G3 tower from 1999. I am pretty sure its the 350 mHz model. I remember adding a second 32 gig hard drive back in the day to spilt my OS 9 and X installs. Wondering what the utility would be in hunting down a processor upgrade? I think I will max out the RAM. This is more for fun/tinkering than anything else, won't be using it for anything day to day.
