Mid 80's with my parents. Bought my own 600mhz G3 12" iBook in 2001. Still runs strong after replacing the hard drive and remembering where all those little screws go.
Holy crap. Pay dirt! Went walking around the basement of work looking for a router to replace a broken one. Stumbled upon all of these machines in a dark corner. I kind of wanted to see if the Apple Scanner worked.
