I got to see one of the original prototypes, at the time it was sitting near the lobby of the Battelle Memorial Institute (who provided much of the R&D for the process and is often forgotten) across the street from the Ohio State University. It was an almost hilarious manual process, almost more like developing film with dry chemicals and powders than the hidden, clean, mechanical process we see today...but it still worked. I imagine it's still there, and if anybody is in the area, it's worth stopping by to see a demonstration of it -- I couldn't find one on youtube, but I did find this explanation. https://www.youtube.com/watch?v=YZKbvPFrc0I https://www.youtube.com/watch?v=YZKbvPFrc0I
