Quoted from Knxwledge:Is it normal for the ramp coil to be pulled in during attract? Game has a Ni-Wumpf MPU and driver board, ramp seems to drop when it's supposed to during gameplay, game works fine otherwise.
Is your Stargate ramp switching to the hold part of the coil when its up? I just put the Ni wumpf cpu in my Mars and when the ramp activates the coil stays in the power position and won't switch to the hold side.
