Perfect, thanks.You can solder the 5v to cn6 next to the analog connector. Pin 1/2 is 5vdc. Pin 5/6 is ground. Pin 3/4 is 12vdc you won't need if you are just using the io for analog Monkeyball
Right, it's just one option to power the Sega IO.You don’t need a jamma extension - just the USB cable between I/O and Naomi.
I think since just the USB isn't sufficient, I'll just run the wires from the stick and start button outside the cab to the Sega IO in with the Naomi. I'd put the panel on a couple of benches right in front of the cab anyway, so the 3' and 5' should be long enough. That way I could also use the panel with a Capcom IO on a supergun. Will the controls work properly if the standard buttons and joysticks are still connected in the Blast and I power the Sega IO through Jamma? It's all passive so I don't see why not..
