Most of us now carry around inside our smartphones more computing power than NASA once had in the Apollo command module. So, it’s interesting to look back at old movies to see how celluloid fiction portrayed computers. Most from the 1950s and 60s were replete with spinning tape drives and enough lights to resemble the Manhattan skyline. Our favorite here at theDiagonal is the first “Bat Computer” from the original 1960’s TV series, which could be found churning away in Batman’s crime-fighting nerve center beneath Wayne Mansion.

The United States government powered up its SAGE defense system in July 1958, at an Air Force base near Trenton, New Jersey. Short for Semi-Automatic Ground Environment, SAGE would eventually span 24 command and control stations across the US and Canada, warning against potential air attacks via radar and an early IBM computer called the AN/FSQ-7.

“It automated air defense,” says Mike Loewen, who worked with SAGE while serving with the Air Force in the 1980s. “It used a versatile, programmable, digital computer to process all this incoming radar data from various sites around the region and display it in a format that made sense to people. It provided a computer display of the digitally processed radar information.”

Fronted by a wall of dials, switches, neon lights, and incandescent lamps — and often plugged into spinning tape drives stretching from floor to ceiling — the AN/FSQ-7 looked like one of those massive computing systems that turned up in Hollywood movies and prime time TV during the ’60s and the ’70s. This is mainly because it is one those massive computing systems that turned up in Hollywood movies and TV during the ’60s and ’70s — over and over and over again. Think Lost In Space. Get Smart. Fantastic Voyage. In Like Flint. Or our person favorite: The Towering Inferno.

That’s the AN/FSQ-7 in The Towering Inferno at the top of this page, operated by a man named OJ Simpson, trying to track a fire that’s threatening to bring down the world’s tallest building.

For decades, the AN/FSQ-7 — Q7 for short — helped define the image of a computer in the popular consciousness. Nevermind that it was just a radar system originally backed by tens of thousands of vacuum tubes. For moviegoers everywhere, this was the sort of thing that automated myriad tasks not only in modern-day America but the distant future.

It never made much sense. But sometimes, it made even less sense. In the ’60s and ’70s, some films didn’t see the future all that clearly. Woody Allen’s Sleeper is set in 2173, and it shows the AN/FSQ-7 helping 22nd-century Teamsters make repairs to robotic man servants. Other films just didn’t see the present all that clearly. Independence Day was made in 1996, and apparently, its producers were unaware that the Air Force decommissioned SAGE 13 years earlier.

Of course, the Q7 is only part of the tale. The history of movies and TV is littered with big, beefy, photogenic machines that make absolutely no sense whatsoever. Sometimes they’re real machines doing unreal tasks. And sometimes they’re unreal machines doing unreal tasks. But we love them all. Oh so very much.

Mike Loewen first noticed the Q7 in a mid-’60s prime time TV series called The Time Tunnel. Produced by the irrepressible Irwin Allen, Time Tunnel concerned a secret government project to build a time machine beneath a trap door in the Arizona desert. A Q7 powered this subterranean time machine, complete with all those dials, switches, neon lights, and incandescent lamps.

No, an AN/FSQ-7 couldn’t really power a time machine. But time machines don’t exist. So it all works out quite nicely.

At first, Loewen didn’t know it was a Q7. But then, after he wound up in front of a SAGE system while in the Air Force many years later, it all came together. “I realized that these computer banks running the Time Tunnel were large sections of panels from the SAGE computer,” Loewen says. “And that’s where I got interested.”

He noticed the Q7 in TV show after TV show, movie after movie — and he started documenting these SAGE star turns on his personal homepage. In each case, the Q7 was seen doing stuff it couldn’t possibly do, but there was no doubt this was the Q7 — or at least part of it.

…

Here’s that subterranean time machine that caught the eye of Mike Loewen in The Time Tunnel (1966). The cool thing about the Time Tunnel AN/FSQ-7 is that even when it traps two government scientists in an endless time warp, it always sends them to dates of extremely important historical significance. Otherwise, you’d have one boring TV show on your hands.
