Noob question about joystick wiring
jptsetme:
Thanks for all the info, guys. If I could make more for the 49 way sticks than it would cost for new sticks and a controller, that's compelling. If I were to buy new sticks, are the $8.50 Happ Competition sticks decent? If I can get decent sticks for what I'd sell these for, it would probably save me a little time and might be better performing / longer lasting. Any suggestion on where to find buyers?
Thanks for the translation link, RetroACTIVE (and thanks for looking at the manual with me Damian). Cool to see this has been done, and I think I could do this with less components than they used since I probably don't need to support all the different mappings they have programmed. Looking at the position table beneath the wiring diagram for the 49 way stick, it looks even easier than I thought to convert the output to 4 way output. Splitting the output into 2 4-bit 2's complement nibbles, the high order nibble is up/down (0 center, + up, - down) and the low order nibble is left/right (0 center, + left, - right) -- anyone see a reason why that wouldn't work?
I'm embarrassed to admit that I drew a little logic diagram of how to do this. 1 4-way or gate, 2 2-way and gates and a not (per joystick), and that's probably not optimal. But if the sticks are worth something as-is, that would probably be the better bet.
Thanks again!

Here's what I drew for left/right -- same for up/down but with pins 6-9. This is untested and I probably won't go this route if the sticks have more value as 49 way sticks. Still interesting.
RetroACTIVE:
To me there are sooo many 8 way sticks out there that will have far better performance than an 'adapted' 49 way it's just not worth the effort. But... if you like to tinker and such then certainly have a go at it. I can see where it's sort of a fun project.
However, if all you have is the 4 sticks and buttons, you have a good deal of 'stuff' to acquire to get to a working machine. Just consider the amount of time and cash and personal energy you have to invest in it and choose accordingly.
It's all fun no matter how you cut it :)

Where would you suggest I sell them? I might go that route.

The B/S/T forum is one place to list them.
Since MAME doesn't support them IIRC, you might have better luck putting them up on KLOV since their user base is more focused on dedicated cabs.
This guy has some listed there for $20 each.
