Rotary Button (Forgotten Worlds)
MameJunkie:
I came across some rotary buttons that I was thinking of making a CP for games like Forgotten Worlds, Front Line...
Two part question with this post.
1 - What other games can you think of that uses a rotary push button?
2 - Harder...It has 5 pins. 2 are for the push button (easy, done)
But the other 3 are 1 gnd and 2 signal. If you look at both signals at anytime, it can be in one of the 4 states in order...
[0,0] [0,1] [1,1] [1,0] back to [0,0]
Rotating one direction changes the signal one way and reversing changes the other way.
So if you are at [1,1]...right = [1,0] and left = [0,1]
How do I wire it up or make a circuit so that all I end up is one for going LEFT and one for going RIGHT?

do you have pics? I don't think I've ever seen one.
MameJunkie:
I'll post some pics when I get home tonight.
MameJunkie:
The left are the rotary buttons.
You can see 3 pins on one side (rotary) and 2 on the other side (button).
On the right, I also got a handful of small LED buttons that reminds me of the old Atari cone buttons (without the cones).

Forgotten Worlds actually used a push-to-fire optical spinner, similar to the Oscar V2, IIRC.
Front Line used an 8-position rotary, similar in function to the Ikari sticks, that had push-to-fire.
