Is there anything like this > that can go wrong when I program a pic12c671? Just as with the 12C508, you should record the 12C671's "osccal" value before you erase it. If you don't, though, you won't really "screw it up"; at worst, the thing's internal oscillator will be a little off. If you're using an external crystal or RC or whatever, it makes no difference. -Andy === Andrew Warren - fastfwd@ix.netcom.com === Fast Forward Engineering - Vista, California === http://www.geocities.com/SiliconValley/2499
