The clone worked intermittently, and the ICD2 worked without any problems ever. (This was an ICSP application.) BTW, this is the clone I'm talking about: http://www.angelfire.com/linux/kitpic/ I'm pretty sure that the ICD2 does not generally use Vdd control, because many of my boards I can program both with the ICD2 providing Vdd and the board providing Vdd. Doesn't seem to make a difference. Gerhard -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
