Jim, (To Jim this is a duplicate, because my original response went directly to him, instead of to the list. So his response came to me. Since this information reflects what is sure to be a breakthrough in otp-erasure-technology, (not to mention a new meaning of "burning chips" :-) I wanted to get it back to the list. Jim--will you please re-respond?) >BTW, I recently succeeded in erasing 150-odd mis-programmed OTP PIC's by >baking them. Think they won't be reliable, though!!!!!! Did you really, or are you just funnin'?
