The city of Wilkes-Barre is having an electronics recycling event and in the lobby of my building are a couple of large cardboard boxes filled with old computer junk, VCRs and even a 19-inch black-and-white console TV - WITH NOBS! Anyway, I've been keeping an eye on it and this morning while contributing an old Sony flat panel, I spotted a PS/2 Model 50. On closer inspection, it turned out to have a DOS 3.2 disk in the floppy drive! Deciding that where there was a PS/2 there would be a keyboard, I poked around and there it was: a 1988 Model M.
Woot!
