There was a Texas Instruments calculator in the database about which I knew nothing. Nothing short of an old post, that is (http://mail-index.netbsd.org/netbsd-ports/2000/03/01/0003.html), which appeared to have described a data entry device that might double as a calculator. Today, I learned that the post was, in fact, an April Fool's joke, posted a month early (or not, if one believes the PS.) So the TI-64 entry is now officially removed from the database.
