So how do you distinguish opamps from ICs, RAM, uPs and programmable
logic ? They are all 'U'. VERY clever.

You're certainly wrong about RAM btw and the op-amp is merely a circuit
configuration.

The Williams tube or the Williams-Kilburn tube (after inventors Freddie
Williams and Tom Kilburn), developed in about 1946 or 1947, was a
cathode ray tube used to electronically store binary data.

It was the first random-access digital storage device,[1] and was used
successfully in several early computers.
