Thanks for the links, but notably there's a large gap between 'a single transistor or diode' and even the simplest real world microchip, such as the SN7400.

Everything before that stage, down to mining ore out of the ground, is understandable.

And everything after that stage is also understandable, at least to the level of an Intel 386 processor.

The gap is what I believe there are no resources online.
