There are two methods of numbering pins in TO92. One is prefered in Europe, while the second one is used in US. Compare a datasheet of BC547 from Philips and for example TL431 from Fairchild: http://noel.feld.cvut.cz/semi/philips/acrobat/7641.pdf http://www.fairchildsemi.com/ds/TL/TL431A.pdf So both programs are correct but to diffeent standards :-( Wojciech Kazubski _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
