The true fathers of the computer are together in the same room!

Awesome nostalgic and still relevant educational!

1. I have been inside Bell Labs.

I was there to review their early efforts to develop a photonic switch for use in optical cross-connection. If memory serves, that was back around 1990. It was an impressive facility.

2. I was so glad when transistor and integrated circuit radios finally were mainstream!

I was still installing and repairing vacuum tube aircraft nav/comm radios even in the late 70's and early 80's even though transistor and early integrated circuits were coming of age.

4. My understanding


is that tubes performed better at very low temps (high altitude) than early transistors.

5. P.S.


I have a 50's Motorola with "mini tubes from right when they were making the transistor transition. Took a 90 volt battery!

6. And they were crap alkaline batteries at that.

Today’s portable electronics, aka super computer smartphones, wouldn’t be feasible unless one wanted to lug around a substantial non-rechargeable alkaline battery pack.
Today’s battery tech is a marvel in and of itself.
