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…

Texas Instruments

Newly-christened Texas Instruments, the company becomes the first to produce silicon transistors for the mass market and designs the world’s first transistor radio. Later this decade, Jack Kilby invents the integrated circuit, enabling the digital revolution and forever changing the world.

Junction Transistor

There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn’t work the same way twice, and on top of that, they were noisy. While one lab at Bell was trying to improve those first type-A transistors, William Shockley was working on a…

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 Tea Company

First established in the last quarter of the nineteenth century by four entrepreneurs (Isidore and Montague Gluckstein, Barnett Salmon and Joseph Lyons), J. Lyons & Co. became one of the largest catering and food manufacturing companies in the world. From modest beginnings as supplier of catering to the Newcastle Exhibition…

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.
