beware that different vendors sometimes put the pin number on different physical pins. TO-18's and TO-39's are some example packages where I have seen vendor #1 number them one way and vendor #2 a different way. Turns out that the E/B/C to physical location mapping was identical, they just mapped 1/2/3 to physical location differently. ugh! Thats why I use heavy symbols exclusively for things like transistors. No need to remember "lets see, was this a cbe transistor" and "which vendor numbering". I just say "give me a MMBT3904". -Dan _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
