Re: Asteriods losing voltage

No, these days we add a tiny extension card to put new edge connections and
a new card edge connector. In the old days we would do that, on location
etc., when a game was down and no time to do it better.

Mind you the wires soldered directly to the board sure made a reliable
game! The card edge connection will burn out again if left on 24/7...
