Culminating a year-long project, [Usagi Electric] aka [David] has just wrapped up his single-bit vacuum tube computer. It is based on the Motorola MC14500 1-bit industrial controller, but since [Da… ...

Computer' using 550 Soviet vacuum tubes With the advancement of technology, the logic circuits of computers have become smaller to the nanoscale, and even palm-sized smartphones have 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 ...

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.

How do you build a functional computer with "only" 113 vacuum tubes and 1450 solid-state diodes is the part I can't get over. I have a feeling some next level hardware wizardry was involved here, ...

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 ...

Transistorized Computer. Bell Telephone Laboratories told last week about a large-capacity electronic computer whose essential works occupy only three cubic feet of space instead of a good-sized ...

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.
