You might have trouble with the pinout, but at least you know it's a 44780. That's as common as a 74LS04. If you're looking for the pinout, have a look at Hantronix's web site for an equivalent device. I'd bet money it's a standard configuration in terms of pin organization. -->Neil ------------------------------------------------------------------------------- Neil Bradley In the land of the blind, the one eyed man is not Synthcom Systems, Inc. king - he's a prisoner.
