“I can understand why you have trouble with the equipment layout, because it was continually changing. Walls were removed or relocated and equipment would be changed after every Apollo mission.

On the floor plan I have shown the location of the SDDS rack, the antenna console and the receiver racks. The wall shown between USB & telemetry was removed before I arrived in 1969, I'm not sure when the wall between telemetry and computers was removed.

The conference room was enlarged and modified several times. All this is enough to confuse anyone, including me after all these years.”

The basement of the Operations Building.

“The lower floor (more like a basement) was a communications equipment room, storage, bedrooms (one converted into a darkroom for me), bathrooms, canteen and a big lunch room.”
