I define normal as NEC once sold them for general purpose use like any other. A brochure exists in English if you like. Visit my other thread for attachments. They used logic, just not in the form of gates. And definitely had no transistor. Accomplished logic with Parametrons, therefore gates...

Gates and switches are neither the only or fastest way to do logic. Well, maybe they are best for now, but as things get smaller... Completely normal computers have been made without switching logic. Once you get your head around a few of the alternatives, transistors become optional glue of...

Just re-read my above post. Even I can't make easy sense of it. Perhaps too many unfamiliar topics have been strung together without adequate context. Would be more understandable with commented drawings. I've already done so at great length in another thread. Far too much to copy it all here...

Transistors, depending the type, have transresistance or transconductance or some messy mix of both. Just how they amplify. At room temperature, I don't see any way around it. Even Josephson Junctions have a small Voltage drop before they superconduct. Voltage * Current = Power. Nothing is free...

You already know NAND and NOR are universal gates that can make any other logic. Now add to that universal list: MINORITY3. Minority being the inverse of Majority. The losing vote of A, B, Zero is NAND. The losing vote of A, B, One is NOR Therefore twice proved universal. That's the sort of...

Transistors and gates are sometimes helpful, but not the only way to perform logic. You might spend some time to look up "Adiabatic Quantum Flux Parametron", which is a Superconducting Josephson Junction majority logic device. Distantly related to Eichii Goto's much earlier Parametron Computer...
