On the previous post, MottZilla asked me whether I plan to create a PCB-mount version of this connector.

First of all, thank you so much for expressing interest in my little project. But to answer your question: currently, I intend to solder directly to the connector just to prove that it works. However, there is nothing stopping me from editing the designs a bit to make a PCB-mount version of the connector. The top piece would then be unnecessary for this purpose, since the pins would be held in place by the board itself, and I would have to adjust the angle of the screws, so that the connector could screw directly into the PCB.

But since I don't even have a concrete pinout for the connector at the moment (it's just a mess of old component legs scattered around, as you can see above), I can't start designing the PCB right away. However, after I prove that this connector works, the next step would be to edit it (as described above) and make a simple ROM cart with it (soldered directly to a PCB, of course).

The thing is, I am currently facing some issues with the connector – I can't insert it into the console properly. At least one pin is either misaligned or just too thick to fit inside the console's connector. So that's what I am fighting with at the moment. Once I manage to insert it into the console (without any of the pins bending/breaking inside) and the console doesn't explode when I turn it on, I will try to wire a ROM to it. And if that works, I will start working on the PCB. At least that's the plan 😉

Be very careful not to short anything out! Seems like a very possible hazard with exposed metal everywhere. I hope you manage to get a ROM wired up successfully.
