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.

The Bendix G-15, a vacuum tube computer originally released in 1956, is now booting, and running code from paper tape. [David, aka Usagi] received the G-15 about a year ago from The System Source ...

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.

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 ...

From the 30-ton calculating machines of the 1940s to Apple's portable laptops of today, see how computers have changed throughout the years. ... and 18,000 vacuum tubes that comprise the machine.

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 ...
