Hey there; Found out what the problem is. I never hook up the VCC pin on my programming headers and Atmel tells me that the avrisp MK II has to have it connected to the target's power line in order to get the correct voltages on the ISP lines. If I want to make any of my boards work with this programmer I will have to go back and retrofit all of them to supply a voltage to this pin. This is actually mentioned in the Avrstudio's help files but not in the manual for the programmer itself. Mystery solved. Craig
