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, ...

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 ...

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 ...

Putting vacuum tubes in a PC might sound a little like adding a hand crank to a Porsche, but at least one company thinks it might be the future of computer audio. Taiwanese components company AOpen, ...

Most vacuums come with a tube that works with several including attachments so that you can clean areas the vacuum, itself, can't go. These attachments are still too large to clean out your keyboard ...

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 ...

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 is one of the most profound innovations in all of human existence. First discovered in 1947, it has scaled like no advance in human history; we can pack billions of transistors into ...

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 ...

While computers tend to run in clean environments, this is not always the case. Any environment might contain a lot of dust and animal hair, and even the seemingly cleanest room will eventually ...
