When we talk about a “computer” today, we generally picture an electronic machine that can perform various kinds of mathematical operations, manage its program flow, move data from one place to ...

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, ...

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 ...

A travelling wave tube shows how far vacuum electronics has come. Mention vacuum tubes and some people (those old enough and/or historically minded) might think of ENIAC, the first electronic digital ...

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 ...

A duo-triode may be 2 Watts. So 113 tubes can be 226 Watts. OK, bias and coupling elements may push past 3 Watts per bottle, 339 Watts. I was just reading of an Intel NUC tiny-computer CPU of nominal ...

For most electrical engineers, the vacuum tube or, more formally, the vacuum electron device (VED), is a quaint curiosity and artifact of the past, and with good reason: The world of solid-state ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This glass vacuum tube has one a ...
