Tubes are back!

And in 460GHz!

In lab testing the NASA scientists have managed to achieve operating frequencies of up to 460GHz for these vacuum-channel transistors – that's 10 times faster than graphene transistors have achieved so far. It also gives us hope of reaching across the terahertz gap.

Long live tubes! We knew this transistor malarkey was just a fad

They sound more organic too.

Do they make a ping when you plug stuff in?

"Maximum of 1.21 Jigahertz when mixed with Graphene components."

The question is though, do they "cold bug" under LN2

Ah a warm and natural sounding computer.

With an amber glow, Fallout style!

They look sublime!

Welcome back to the house-like-computers era again ;-)
