Whoa, I didn't know they could switch that fast! Because afaik vacuum tube computers were measured in thousands of mathematical operations per second
- volemo 2y agoI guess it’s highly dependent on the type of the tube. The documentation [1] for the 6N3P (the one Mike uses) talks about input resistance at 100 MHz, so the tube must handle at least as much. [1]: https://www.istok2.com/data/575/ https://www.istok2.com/data/575/
- immibis 2y agoKeep in mind that's in relation to amplifying analogue frequencies around 100MHz. It doesn't necessarily mean you can make digital logic that runs at 100MHz
