First, the picture. Can you pick out which one is the old computer?

Yes, the old one still works, although there are times when I've had to hard reboot it three or four times in a row to get it to startup all the way. And I've been bringing a laptop (from grant money) home from school for the last year and a half or so as some things I just couldn't do in OS 9 anymore. But I think that's still pretty good - roughly 10 years of usable life with a little upgrade along the way. I doubt I'll make it 10 years with this new computer, but I'm trying to picture what the specs might look like in the spring of 2018 . . .
