Quoted from Cheddar:You probably need to contact Swemmer to troubleshoot. I don't know if the Swemmer have the 5 second delay before they start but that indicates a slam tilt in a regular board. Is there a slam tilt bypass option on this board?
Swemmers are about as close to gottlieb boards you can get (nvram circuit is different), so system 80 have 5 second delay, 80a comes on instantly just like original games
I forget if they have the slam tilt bypass though
