A friend of mine from grad school days collected a large number of off-the-wall opcodes while working on the Scanning Transmission Electronic Microscope at the University of Chicago. What follows is a copy he forwarded to me after I had gone off to work at Stanford. I know David won't mind. BTW, he's no longer at UC, so updates should *not* be sent there.

Rich, the Useful Opcodes tome has been revised a bit. Here's the new version.

Rich Alderson You know the sort of thing that you can find in any dictionary
of a strange language, and which so excites the amateur philo-
logists, itching to derive one tongue from another that they
know better: a word that is nearly the same in form and meaning
as the corresponding word in English, or Latin, or Hebrew, or
what not.
