Any idea? i can get a vid of what its doing. First things first... Check the voltage. You need to make sure you have +5V. Here's the Zaxxon pinout: http://www.mikesarcade.com/cgi-bin/spies.cgi?action=url&type=pinout&page=Zaxxon.txt you need to put your DMM probes on A + C or 1 + 3 on the edge connector and see if you get +5V Title: Re: Zaxxon Machine.. runs but keeps reset looping Post by: STEVESPEEZE on January 24, 2014, 11:04:32 pm yeah cuz the video is not resetting , it just sounds like the sound is looping
