Years ago, in a junk bin far away, I saw a device which was a small plastic box with protruding pins in the form of a 14-pin DIP — so that you could solder jumpers or small axial components to the inside end of the pins, close it up, and have a module of your own design that could be plugged into a DIP socket.
What would these be (or have been) called?
I have a use for one, if I can find it. (Of course, I could abuse a DIP socket by soldering or just pushing individual leads into it, but in my experience, sockets have shorter (or thicker) leads and a shape not best suited for plugging into a socket, and it would be an open frame rather than enclosed. If that's my only option, I'll take it, but I'd like to evaluate the alternative I once saw.)
