We have occasionally featured vacuum tube computers here at Hackaday and we’ve brought you many single board computers, but until now it’s probable we haven’t brought you a machine that ...

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 ...

If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too. The army, with its need for ever-faster and more efficient calculations ...

A vacuum tube is just that: a glass tube surrounding a vacuum (an area from which all gases have been removed). What makes it interesting is that when electrical contacts are put on the ends ...

Google's head of quantum thinks we could get real-world applications of quantum computing in just five years, while Nvidia claims it's more like 20.

While the first computers were mechanical and famously ran on vacuum tubes, there were other schools of thought that introduced a different kind of computer – one that ran on water. In the 1930s ...
