A long time ago, I use to work on a very old analog computer made with tubes. It was 120 separate op amps that had a +-100V swing. Yeah, if you got on that “One” it was very painful.

If you’re looking for something a little more accessible to get into the world of vacuum tubes, this single-board tube computer fits the bill. Continue reading “Retro Computer Goes Back To The ...

Researchers from UC San Diego are using vacuum tube technology to develop more efficient computer processors. The research could result in faster microelectronic devices and better solar panels ...

While semiconductors replaced vacuum tubes as the go-to way to conduct electrical current in our gadgets decades ago, scientists are looking to bring them back for computers used in space.

Vacuum tube technology is making a comeback, with physicists hoping to use miniature 'vacuum transistors' to make increasingly-smaller computers. The development comes just as the laws of physics are ...

The First Transistorized Computer . January, 1954: If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too.

But there's a chance that vacuum tube technology could make its way back into computers—albeit without the vacuum—thanks to NASA research that has put together nanoscale "vacuum channel ...

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 ...

Vacuum tube computers, including the Atanasoff-Berry Computer (ABC) and the Electronic Numerical Integrator and Computer (ENIAC), signaled the transition from mechanical to electronic computing in ...
