Time to Abolish ICs

Sounds like a threat to me. You got an emp up your sleeve?

Not when things are just starting to get interesting:

Oh, but I do.

I've even built vacuum tube circuits. Booyah!

Tim

Sounds like each chip has an LC oscillator on-board, and a mess of them are supposed to injection-lock. Terrifying.

John

I read it as one osc per chip, but the clock lines are so arranged that there's no (little) loss because they turn back on themselves moebius-wise so you get a traveling wave reinforced by inverter pairs distributed along them, and you can pick off whatever phase you want by carefully choosing the pickoff point. Apparently the tech is good at least to 3.5 gHz in the pilot version. Allegedly there's more room for improvement; we'll see.

Mark L Fergerson

Did you build the actual vacuum tubes?

Now, now, Jimmy, no-o-o-o-o one's trying to threaten you.

I got empathy for de WHOLE WHIRL!!!!

Unfortunately no, I don't have any glassblowing or vacuum equipment.

Tim

Get a copy of this book:

which not only describes how to build (and use) your very own toobs, but includes instructions on filling them with vacuum.

Sounds like you're missing out on some fun!
