Nice work as usual Darrel. This is exactly the problem I am having. I did google it but I guess I wasnt using the right key words.

So I guess the moral of the story is: 18F1320+TMR1(w/ext clock)+MCLRE_OFF = bad

Too bad I dont have a JMD programmer. I guess i'll see if its worth building one just to revive these 3 PIC chips.
