Vacuum tubes fueled a technological revolution. They made the amplification of signals a reality for transatlantic telephone cables (and transcontinental ones too), they performed logic for early ...

Commonly thought of as a primitive precursor to the modern transistor, vacuum tubes were the building blocks of computers in the early 20th century, and computers built using them filled entire ...

Enormous dimensions, complicated military calculations, and thousands of vacuum tubes—this was the early supercomputer. Engineer Thomas Kite Sharpless gives a demonstration of the EDVAC at the ...

Which is why NASA's Ames Research Center is going back to the future with its new vacuum transistor -- a nanometer-scale vacuum tube that, in early testing, has reached speeds of up to 460GHz.

The massive machine weighed just over two tons with over 5,000 vacuum tubes. This early computer operated for 13 years or 51,349 hours before being dismantled. In the 1960s, ...

Little did they realize how different that early computer was from the ones that ... Filling up a 30 X 50 foot room, ENIAC was made of 17, 468 vacuum tubes, 70,000 resistors ...

The Vintage Computer Festival East is a once-a-year museum exhibit in Wall, New Jersey that shows off vacuum tube and transistor computers from the 60s, 70s, and 80s.

Early computers used vacuum tubes to serve as switches for digital logic calculations. These vacuum tubes consisted of metal electrodes inside a glass tube and could turn the current flowing ...
