Yesterday at while at Goodwill looking in the bins I found what looked like a strange calculator. It turns out to be the keyboard (UC-2100) for a Seiko Data 2000 computer watch. Had I knew at the time I would have been on the lookout for the watch, anyway I got the keyboard for 50 cent. Also found a lot of stuff the looks like it came form a Computerland store in FL. I ended up spending close to $40 two large boxes and five very large bags full of stuff to play with. John K.
