Anyone recognize this PCB?

I find "socket" and "pin" more confusing, because, honestly, my initial reaction is that they refer to the same sex. D-shell connectors normally have male and female as seen from the point of view of the signal-carrying pins reversed from male and female as seen from the point of view of the outer shell. To me, "socket" is the female side point of view of the signal-carrying conductors - which are the same side. I never thought about it, but you're right: a 13W3 has *four* potential views of male and female: the DB shell, the 10 signal pins, the three co-ax signals from the POV their own outer conductor and insulating body, and the co-ax signals from the POV of their axial conductor. And, of course, it's as confusing as possible: each sex of connector has two of those male and the other two female. Oddly enough, I tend to view the co-ax "pins" as being the same sex as the 10 individual pins, *but*, a phone plug/jack in isolation I view the other way around, from the POV of the axial conductor.
