For great color photographs of the system, see Scott Beale's images posted on Laughing Squid, where EDW Lynch describes the scale of the machinery involved: 

The heart of the system was the IBM AN/FSQ-7 computer, which at 275 tons is still the world’s largest computer. Each computer had 55,000 vacuum tubes, required a half acre of floor space, and operated on punch cards. There were 52 AN/FSQ-7 computers around the country.
