At the last vcf here in California a fellow, I forget the name, brought in two tables that
connected together, could generate a damped sine wave. It used mostly Manco erector like
parts. It had some really great 0 backlash torque multipliers. They had to be finely tuned
so as to have almost 0 load on the integrating disk.
WW2 fire control computers were used on US battle ships. They had to compensate for things
like coriolis effects, mass, distance and charge.

I haven't looked for a book, but if you'll settle for Wikipedia:
