Vaughn It's not too hard to make your own using djboxsym. http://www.gedasymbols.org/user/dj_delorie/tools/djboxsym.html Mark, Thanks for the suggestion. I did already make my own, by copying the file for the DIP-40 part and changing it, mostly by editing the text in emacs and then by moving stuff around in gschem. Next time I'll have to check out djboxsym.

Vaughn The pins on the footprint are numbered sequentially starting at 1. Pin functions are assigned in the schematic symbol no the footprint. The specifications you want to look at are number of pins, pin spacing (pitch), and lead span. You need to compare the footprint to the package specification not the schematic symbol.
