NORC (Naval Ordnance Research Calculator)

The NORC was a vacuum powered computer built by IBM for the U.S. Navy and was delivered in Decemeber, 1954. It was one of the most powerful computers of it’s day, using Williams tubes for memory and had a speed of 15,000 operations per second. It sported a total of…

TRADIC

TRADIC stands for Transistor Digital Computer, and as the name suggests this was the first machine to use all transistors and diodes and no vacuum tubes. It was built by Bell Labs for the U.S. Air Force, which was interested in the lightweight nature of such a computer for airborne…

Regency TR-1

Regency Electronics produced the first commercial transistor radio, the Regency TR-1, it hit the consumer market in October, 1954. It featured four germanium transistors operating on a 22.5-volt battery that provided over twenty hours of life (tube radios with batteries only lasted several hours at best-ref). Several colors were initially…

IBM 701

The developers and builders of the 701 had created a computer that consisted of two tape units (each with two tape drives), a magnetic drum memory unit, a cathode-ray tube storage unit, an L-shaped arithmetic and control unit with an operator’s panel, a card reader, a printer, a card punch…

Whirlwind Computer

The need for a system capable of true flight simulation was one of the outcomes of World War II, and the Navy commissioned MIT to research and develop one that could help them train bomber crews. After seeing the results of the school’s study, Project Whirlwind was created with Navy…

Lyons Electronic Office (LEO)

England’s first commercial computer, the Lyons Electronic Office, solved clerical problems. The president of Lyons Tea Co. had the computer, modeled after the EDSAC, built to solve the problem of daily scheduling production and delivery of cakes to the Lyons tea shops. After the success of the first LEO, Lyons…

SWAC

The National Bureau of Standards completed its SWAC (Standards Western Automatic Computer) at the Institute for Numerical Analysis in Los Angeles. Rather than testing components like its companion, the SEAC, the SWAC had an objective of computing using already-developed technology.

SEAC

The beginning of image processing and the construction of the early National Bureau of Standards Electronic Automatic Computer (SEAC) computer made possible the experiments that led to image processing. SEAC was the first electronic computer with an internally stored program in the United States government. It was the first of…

CSIRAC

The CSIRAC was Australia’s first digital computer and the fifth stored-program machine in the world. It’s first test was run in November, 1949 and it was built by a team of engineers and scientists led by Trevor Pearcey and Maston Beard. Input was done on punched paper tape instead of…
