I've contemplated recreating this machine, in part because I'd like to "play" it. There is plenty of material on the design and workings of the device but there is precious little material on how the operators (referred to as "girls" in the demo) were trained, a process that took months. If anyone has access to such training material, please contact me: The_Amazing_Dr_T (remove underlines) at gmail dot com
