I picked up a sack full of these
<http://www.classiccmp.org/hp/PDP-8%20cards/cab-kit.jpg> last week. Thom
says that they're valuable but I was just going to rob so parts out of
them. If they're worth much I'll use them for trading material or E-bay
them. if they're not worth much, I'll just pull the parts that I want and
pitch the rest.
