For the main engine controllers, there was a lot of work and risk

Why? PWM flew a decade before on the Posiedon missile. It wasn't
exactly new or untried.

I typed from memory and started to hit the notes for some details. I can dig
deeper to search if you wish (a tad busy or I would do it now; perhaps during
a work break later this evening) and this was more or less available.

Yes, I'd like to see some more. I find it hard to understand how PWM
can fly on a strategic missile, but be 'risky state of the art' a
decade later.
