But you have to admit the good ones were breathtaking. Too bad they will not be preserved.

And yes, their "machine sitter" in the booth was there because of the well-known cantankerous nature of these shows. They were certainly not a kiosk computer playing back a PowerPoint.

I doubt that many (if any) of these will ever be seen again in their full glory. If we wanted to classify these as "formats", we would probably need to classify each configuration with each manufacturer's control protocol as a separate "format". You did mention the two-wide with centre overlay as a common format. I do recall seeing a number of these at National Park venues. I was thinking about the more elaborate ones that added another panel and another splice (at least) for five stacks of projectors.
