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 ...

But before even those transistor-based computers is a retrocomputing era rarely touched on: the era of programmable vacuum tube machines. [Mike] has gone back to the 1950s with this computer which ...

It could perform a million logical operations every second, still not quite as fast as the vacuum tube computers of the day, but pretty close. And best of all, it operated on less than 100 watts ...

and it was also used in everything from radios to televisions to the first computers. The audion, or triode, at the heart of the vacuum tube is what the transistor was built to replace.
