Update..I fixed the SEL bug and have attached all the Altium source files for this projects as well.

The JST NH connectors won't fit unless we go beyond the pretty 5x5cm PCB size. Is that something you want, PBJ?

My hands aren’t steady enough to manually pin a tiny 15 pin connector. It’s current year, let’s do something more accessible.

I’m good with a slight expansion of PCB size for easier soldering. I’m in so deep at this point that all reason has left the building.

I also wanted to point out that the donor joystick I used is down to $21 shipped on Ebay now. I think it would be impossible to assemble anything cheaper than this.

I ordered some regular size 8 Pin DIN connectors, so now I can make these for TurboGrafx 16 or make PCE -> TG16 adapters. (or I guess go the other way if one is crazy enough)

:cheers:

Too bad shipping that stick to the Netherlands is like 25 bucks.. But to continue the party, here is a slightly larger rev B that adds JST connectors all over the wazoo:

Is it possible for pdco_arcade to do a quick review? I might have done parts of this project over beers.... :cheers:

Oh man, that's the stuff. Nice work.

I've assembled a couple PC Engine -> TG 16 controller adapters. Since my after market controller is really TG-16 and came with a PC Engine adapter, I can now daisy chain two adapters to test everything out.

I'm happy to report I actually remembered to put the boot on the cable the second go around. First one I had to cut the boot, slide it over, tape it back together.

I also found that with my high tech wiring diagram (in background) and a rough idea of which color wire is which, it's easier to just solder 1-4, 8, and then 5-7. I buzz out continuity on each wire right before I solder it. Much quicker than trying to label them first. It's just 8 wires, bro.

Anyway, point being that if anyone is interested in one of these things, I can now assemble it either way.
