Thanks for the information. I am not an electronics guru but I have made my share of mic and rca cables over the years and successfully hacked a keyboard for 2 sticks and 7 buttons. It sounds like I might need to build a circuit or something more than just sticking wires from both devices in the OPTI-PAC and screwing them down. When you do yours I would appreciate seeing any pictures, schematics, etc. Great idea with putting 2 spinners on instead of just one.

: You could connect them in parallel and just feed one at a time with power. You won’t be able to use them at the same time but you will be able to use the same interface circuit. This is what I am planning to do. Have one trackball and two spinners (one at the x-axis and one at the y-axis of the interface circuit).

: : I want to have a track ball for some games and a spinner for other games. Since I will use these controls independently, can I wire them both to the same OPTI-PAC?

: : Thanks

I think that the switching between the spinners and the trackball could be as simple as a "switch" (read on) EmuMannen 7/07/2000 (0)
