yeah I understand the theory behind it, had to develop a small 555 trigger circuit back in Automotive Electronics class over 10 years ago
So will need to dig up that knowledge a bit...
Will see when I get the cart back and wire up the trackball to it.
After that I will follow the schematics posted earlier and see which 'other' connections are there for the hopper etc.
I'm sure we will figure it out, and as @MetalliC has the game running in MAME he could pitch in his thoughts on what needs to be wired on the actual hardware
No rush for me now as I first need to get the cart back anyway
