I assume that you mean Carver Mead and Lynn Conway, Introduction to VLSI System Design 1978.
I am enjoying this thread!

There's always Rochester Electronics.. "leaders in the trailing edge"
(no kidding, that's their slogan)..
They buy old fabs, masks, etc, and keep producing small runs of older
parts. For a price.

For digital stuff, small boards with FPGAs or microcontrollers on them
are probably the sweet spot for small runs.
The same is not true for analog.
