Hello, I recently found a Vectrex controller and upon bringing it home and plugging it in, I noticed that the buttons do not work. I checked the controller on a friend's Vectrex as well and found it to have the same issue there. I took it apart hoping that it was simply the board needed to be cleaned or something needed resoldering. But I found everything inside to be in great condition! I checked all of the contacts with a multimeter and then moved to the D9 plug. I stuck a piece of wire in number 8 in the plug and then went through each button. Wire in 1 and a wire in 8, touch the multimeter to each wires, hit the button and BOOM I have a complete circuit. And so on and so on. So. The only thing I can think of would be that since NONE of the buttons are working with the Vectrex, that there is a problem with the contact on number 8, which is common on all four buttons when completing a circuit. Is that logic correct? I know JUST enough of this stuff to have built my own controller out of a Vectrex, so maybe I am missing something.. The plug end is also extremely beat up at the end. See picture below. I don't know if someone was gnawing on it or what.
So my question is, if there is an issue with the contact on pin 8 on the controller, is there anything I can do about it, sans wiring up a new cord? I'd really like to keep everything original as possible, but I don't see a way to get inside the plug to see if I can't tighten that female pin of the plug. Any guidance would be greatly appreciated. Thanks!!
