I still remember being amazed by many things on that tour, but the clear star of the show was the Kodachrome line, which again, was one of the original factory-scale Kodachrome lines. I'm not sure how many they ever built, but I don't think even all KPL labs had them. It was an enclosed structure inside the larger factory building, something like 100 ft. long, and tall and wide enough to drive a car through. We could walk around it, but couldn't look at the actual machinery inside the structure because it was all in the dark, of course.
The employee and family tours at the North Vancouver lab were able to do this better, because they closed the line down for the evening, and ran it in the light, loaded with reels that just had the one mile of leader and one mile of trailer on them - no one mile of spliced together customer film in between!
They even showed us how the operator would deal with a splice failure in the midst of a run - a truly frightening scenario.
That room and machine was clearly smaller than Palo Alto - it was only the size of a city bus
