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.

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.

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 ...

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 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 ...

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 ...

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 ...
