We found this at an estate sale. It's dated 1985 and has demo on the chip behind the plex cover. Anyone know what it is or of any value? http://tinypic.com/r/24azz2f/8[^] I can't find any on ebay.

That is the "reader" side to one of the plastic card door unlocking entry systems. No, that was utter BS based on my misunderstanding of something. Here's[^] what the thing is. Wow. "Dial-up" security. This must have been pretty cutting edge in 1984. Marc
