One of the big wins for FORTH was Kitt Peak. A person I worked with who
had moved on to UA astronomy department tried to recruit me. They have
other sites on Graham, Bigelow, and others including Kitt. I'd spent
several winters in Why, AZ, which is west of Kitt just after you leave the
Rez but didn't want to be a year round AZ resident. Nice place to visit.
At least UA is in Tucson, which is semi-bearable.

In 1971 the 8080 and other MPUs were a dream on the drawing board.
Industrial applications were all about relay logic. Solid state slowly
advanced but the first steps were shaky. An industrial forklift charging
station or a motor controller starting a 50 HP induction motor tend to put
some nasty spikes on the plant wiring. With 120 VAC relays nobody
noticed.
Logic is logic. If you can do ladder diagrams you can do TTL. You can also
do if
(a && b)
{
activate_solenoid();
}
It's all the same.

Not to get into the pros and cons but covid proved how easy it is to
generate a huge cluster fuck.
