We had a bunch of these (about 25 I think) at Sandy because they were very handy for testing all the cards we made - it was much quicker to change out cards, and if there were any subtle timing issues they would surely show up on the extender cards. They were identical to the one in the photo. I believe they were a standard part fairly common at the time for industrial applications.
