There’s a Blue Bendix in Texas, and thanks to [Usagi Electric] it’s the oldest operating computer in North America. The Bendix G-15, a vacuum tube computer originally released in 1956, is now booting, ...

Culminating a year-long project, [Usagi Electric] aka [David] has just wrapped up his single-bit vacuum tube computer. It is based on the Motorola MC14500 1-bit industrial controller, but since [David ...

See refrigerator-esque and semi-trailer-sized models, including an early mobile computer. The Vintage Computer Festival East is a once-a-year museum exhibit in Wall, New Jersey that shows off vacuum ...

I have always been interested in electronics engineering ingenuity used to solve “impossible” problems. One such problem was the task of deciphering the German Army's most secret transmissions during ...

The transistor revolutionized the world and made the abundant computing we now rely on a possibility, but before the transistor, there was the vacuum tube. Large, hot, power hungry, and prone to ...

Researchers have developed a vacuum tube prototype that is both fast and tough against radiation, making it ideal for computers in space. Researchers have developed a vacuum tube prototype that is ...

Most people associate vacuum tubes with a time when a single computer took up several rooms and "debugging" meant removing the insects stuck in the valves, but this technology may be in for a ...
