I remember a while ago there was some commentary about batch codes and people were trying to decipher the final 4 digits. While it was accepted it didnt seem to matter to most people some decided batch codes with A= more voltage and b vice versa, not important. I remember reading C codes were more rare.... I just got a chip with a D in the batch code.... while I realize asking this will immediatly start a flame fest, has anyone else seen a batch code with a D in it?
