I don't know if anyone cares, but at ~9:15 there is a PDP-7 shown. To the right Max Mathews is shown sitting in front of a display with I assume MUSIC IV on it. This would make that PDP-7 part of the Graphic II terminal made by Bill Ninke. It is this PDP-7 that Unix is later written for/on.

So I believe this specific PDP-7 (serial number 34? It was the only one shipped to Bell Labs with a display before 1969.) is what would later become the "Unix genesis machine". Unfortunately, I also think this is the only footage of it, at least online. Anyone care to correct me? Please.
