Chicago Theatre projection booth: Who knows which ports were cut for which projectors and what advances in technology? The booth was added to at some point. Who knows its story?

This is what we do know - The booth itself is equipped with 7 distinct viewing and operating ports used over its century-long lifespan:

Followspot Windows: The leftmost windows (typically ports 1-3) house powerful followspots.Slide Ports: Center ports historically cut for still preshow slides.Film Projectors: Rightmost windows (ports 5 and 6) are configured for 35mm film projection, with lower ports for the machines and higher ones for the operators.
