Thanks Greg and David. I am sort of tempted to try a few of those HLL logic type H158 chips, because they have an identical pinout to the 8T01, but these HLL ones run at 10.8 to 20 volts, not the usual 5 volts. I am not, however, up for trying any that datasheets cannot be located for. Anyone have any idea about similarities and/or differences between genuine U.S. made 74141 and the Russian K155 versions? I know they are pin for pin compatible and work the same way, but I heard there are a few subtle differences. Any ideas on that? Thanks. -Chuck
