                               First thing I did. Last time it was a red one.
    No Switch.
    All contacts look good.  Five volt power supply looks good. I now believe
  that the uP is being reset (about once per second) maybe by the copy protect
  IC ( a proprietary, Nintendo owned chip).
    I don't suppose anyone has noticed Nintendo on the net ?  It's not likely
   I'll be able to buy a new chip but would have a better chance if I were
   to correspond with a real human being instead of some robot in Customer 
   Service. :)
