I know.  I mean, I am used to datasheets being wrong, with some errata 
listed at the end, but I don't think I've ever seen a wrong pinout, 
especially on a DIP-style part.  It begs the question of whether CBM 
engineers noticed it long ago and updated the copy, but the updated copy 
was never circulated, or it was circulated but never archived.
