Air Force, was called a “Giant Brain” by journalists who covered its creation, noting the speed of its computing capabilities. Perhaps part of the reason why the computer was so big was that its creator were trying to top SEAC, which drew a bit of buzz upon its release. This van also has internal dimensions of 39 x 7 x 9 feet. 2 contains DC power supplies, 6 tons of refrigeration capacity, and 1,700 cubic feet of spare space. Its internal dimensions are approximately 39 x 7 x 9 feet and weighs about 12 tons. 1 contains the control console, input-output, computer, storage, and 12 tons of refrigeration capacity. Per a 1961 survey of the computer industry by the Ballistic Research Laboratories, the computer weighed 20 tons and required two separate trailers to function: But the machine, based on the earlier SEAC computer produced by NBS in 1950, may have been the least-portable “portable” device ever created. Army Signal Corps, is widely believed to be one of the first computers designed to be transported around. The machine, produced by the National Bureau of Standards (NBS) at the behest of the U.S.

Looking at a picture of the DYSEAC, it’s bizarre to think that anything so huge and unwieldy would be considered “mobile” or “portable,” but in the context of 1950s computing-before a time when most people even had the chance to sit in the vicinity of a computer, let alone use one-it sort of made sense. Before computers had transistors, portable computers looked like the DYSEAC The DYSEAC computer, which was really freaking large. (Despite being pushed into another team, Henrietta still worked closely with NBS’ computer team.) Alan would become a key figure in the creation of the DYSEAC, one of the first “portable” computers ever produced. The couple, speaking to the Computer History Museum in a 2004 oral history, noted that they were not allowed to work directly together due to a nepotism rule at the bureau, which led Henrietta to voluntarily leave the bureau’s computer team and work with its electron tube laboratory instead. Henrietta Lenier, an employee of the National Bureau of Standards in the 1940s and 1950s, discussing how she met her husband Alan. A year later we married, and after we married I said to my supervisor: ‘You told me to get Leiner, so I got Leiner.’” My supervisor asked me to help with the paperwork and ‘get Leiner.’ I did help with the paperwork and Alan joined our group. “I was working at the Bureau in a mathematical group that was eager to recruit him, because we needed someone with his computing skills.
