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 ...

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 ...

In the 21 st century, it is all too easy to take today’s powerful microcomputers for granted, and as artificial intelligence continues to make inroads, the assumption is that massive amounts of data ...

Remember those old-timey room-sized vacuum-tube-powered computers with less processing power than your smartphone? That tech might be making a comeback, thanks to work from scientists from UC San ...

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, ...

A reconstructed World War II-era British computer is trying to crack messages enciphered on Nazi hardware in an event sponsored by the National Museum of Computing, located at Bletchley Park, the ...

On Oct. 3, 1950, three scientists at Bell Labs in New Jersey received a U.S. patent for what would become one of the most important inventions of the 20th century — the transistor. John Bardeen, ...

From the earliest mechanical devices to the most advanced quantum computers of the present, the history of computing is a fascinating trip spanning thousands of years. Let’s explore the significant ...

After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in preparation for SPICE simulation. The availability of hierarchical blocks for ...
