is there anyway to hook up a spinner for tempest on the 412n1 vert pcb?

Wire your directions to L and R on the JAMMA harness. I see no reason why that would not work.
Interesting. I've wired a trackball like that.
I've indeed seen certain games do that, for sure.
I just remember these bootlegs having separate connectors.
I suspect that they've set the tempest controls up for a trackball, not a spinner. IOW, a regular spinner will only move in x or y direction. However, you may be able to connect the spinner to both X and Y and fool it into working, at least for tempest. In any other game (i suspect), the spinner would make the character move in a diagonal direction.
Edit - The more i think of it, the less i think it'll work, if it is truly set up for a trackball, then when the cannon is on the bottom right hand side, it'd be looking for an up in the y direction to move up, when the cannon moves over to the top left side, it'd be looking for a down movement to move the cannon down. Unfortunately, you'd have to move the spinner in the opposite direction to keep moving counterclockwise (if indeed its set up for a trackball).
Having said that, is there per chance a setting that you might could change for spinner vs trackball?
