Videos and text descriptions of the PDP-8 and Teletype operations were part of the MARCH exhibit. They were shown on a Linux system with an internal set of Web pages similar to the Web pages now on my site. I don't have the videos on my site, but David Gesswein (who created them) has them on his PDP-8 site. Check the following links below to see those videos.
