Dual arcade steering wheel help.

(1/2) > >>

chrimeg:
Hi,

I managed to purchase a used dual steering component for $20.00. Both wheels are 360 degree optics & not pot controlled. Problem is I don't know how to hook it to my opti-pac.

I've attached a few images of the component to see if anyone can help.

What game did it come out of? What wires go where on the opti-pack?

Thx

chrimeg:
Just a few more pics for detail just in case....

chrimeg:
I've listed the pins that are currently used and and the wire colors going to them.

The white and red wires look like 16 gauge while the brown and grey are much thinner.

The IC controller ont the board is a 74LS14 PC. Currently trying to find schematics for this IC to see if I can trace the connections.

Did you look at the optipac's web site? http://www.ultimarc.com/optipac3.html
Each wheel could be wired as one axis of a trackball. Then one would set up mame to determine which is which player.

Yeah I've been looking at that. Just can't determine which connections feed where off my PCB spinner board. Not sure which is ground, which is hot etc.
