As you can tell I am not very good at getting rid of old computers. I had a couple of 386s that I finally disposed of last time I moved, but you never know when you might want an old SE/30 to turn into a fishtank or something. There are also a few PCs (running linux or FreeBSD) and a NeXT cube floating around here somewhere.
