I found possibly the first article about
computer logic design in Sep-1948 magazine,
https://www.worldradiohistory.com/Archive-Electronics/40s/Electronics-1948-09.pdf
On PDF page 114 is
DIGITAL COMPUTER SWITCHING CIRCUITS
Learn all about the flip-flops, registers, shift registers,
arithmetic circuits, and digital numbers.
And how to build a decoder using diodes and resistors.
Hmmm... looks a lot like a PLA.
There's also an article on PDF page 72 introducing...
The TRANSISTOR - A Crystal Triode
"Germanium crystal with two cat-whisker contacts has characteristics of grounded-grid triode amplifier, provides 20 db gain, 25 milliwatts output
at frequencies up to 10 megacycles."
They predict it will replace vacuum tubes in many applications
but I remain sceptical.

We obviously cannot breed enough cats to be able to collect all those wiskers!

Anyway, cats are needed for antigravity drives.
By fastening an upright piece of buttered[*] toast to a cat's back,
you create a paradoxical object. Since cats must land on their feet,
and buttered toast must fall butter-side down, the combined cat-toast
object can exist only by negating the pull of gravity- i.e, by
levitating.
This explains both the purring sounds heard from some UFOs and also
the heavy electrical charge UFOs have been seen to possess (likely
caused by many cats in the drive core rubbing against each other).

[*] jelly or jam works too.

When can we put it into production ??
