I've seen 3-4 cases where a gang of copycats winds up in a shop asking for a specific chip (that was erased or remarked). They are always sent on their way in honest places, even if you can tell immediately what the chip is from the osc pinout etc. Let's say it slows them down. It won't stop the real bastards who are backed by a factory of course. Peter -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
