CuriousMarc, a volunteer at the Computer History Museum, recently finished a video series restoring two Model 19 teletypes into working order. It's a long series but eventually explains how the devices work at all levels, and shows off some of the more niche features of the ttys. Well worth the watch. [VIDEO]
