I think I should explain my 'closefistedness' and why I only need the pinout
I bought a cab with a trackball....I assume it used to be Golden Tee. It was changed to Simpsons Bowling with a set of marquee, instructions and wiring...and of course the pcb. I got the cab not working and found out that the pcb is dead, unrepairable. I tried the game on my mame test cab and thought it was boring. So I searched for a better game and was pointed to World Class Bowling and to Shuffleshot. I liked the latter very much and so I bought a PCB in USA, did some artwork (controlpanel and marquee) and now it is running. I'd like to insert a jamma switcher and add World Class Bowling to the cab. But then I would need a 2nd cable for the trackball signals and there is the original (Simpsons Bowling) harness still inside the cab. But it's 6 pin and WCB's connector is 7 pin. So I thought I could make an adapter if I knew the pinout. But, silly my, I can still trace the wires and see where they end in the trackball connnector
