I was just thinking, imagine trying to use a modern-day smartphone for this. So much complexity how could you be sure the missile would even get off the ground. There is a big advantage to systems that engineers can mostly "keep in their heads". Very few systems are that way these days.

A Teensy 4.0 just as an example which is much more like this. Has a bunch of general purpose I/O; it's quite powerful; and you can essentially keep it in your head.

I can't imagine trying to discover & isolate faults on something like this though.

THAT is not a computer. THIS is a computer.
