Is there a ground plane that's not really visible here?, it looks as though C6, C7, the 16mhz crystal caps are only connected on one terminal, ditto for C1, C2, C4, C5, and the center terminal of IC1.... and that JP2 #1 and #2 aren't really doing anything (future use?).. I will have to go out on a limb and say there's a ground plane I'm not seeing somewhere?
