Thanks for the correction, Simon.  I don't know how I got through my

For anyone with 30 minutes to spare on the history of ASCII, I

American Standard Code for Information Infiltration" by Tom Jennings.
The URL has changed lately such that Google doesn't put it at #1; it's
now at: http://worldpowersystems.com/J/codes/.
