This video is worth 11 minutes of your time, to be sure. - Although the machinery used is not that built by TELETYPE, it goes into great detail about codes, code bars and switching. - All done at very slow speed, with special visual gadgets to get the idea of "ON-OFF" switching to create the individual characters.

I have a fondness for Teletype machines, and I learned to type on a Model 19 at the M.I.T. radio club, so I'm publishing this as a bit of whimsy for Telecom Digest readers.
