How good is the temp. control on your oven? I am not saying this is imposable just unlikely. More likely is that you added capacitance when you went from a bread board to the PCB or that interference that was physically more spread out got closer when you made the PCB layout. I notice the CPU is socketed could you please try powering up the board without it. -- http://www.coe.neu.edu/~efoss/ http://evanfoss.googlepages.com/ _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
