that one has me, it only has two wires and the back of the card has no
copper. I could see in the late 60's and 70's someone making a answer
back unit using diode logic. Al thought there are only 7 long traces,
quite a few time only 7 bits where used. When I do the full service
this winter I'll wrap it up and add it the boxes of "what the heck was
this for".
