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.

There are Navy training films online (on YouTube, I think) describing in some 
detail how those machines worked.

For the British and Commonwealth version search for "admiralty fire control clock" or "admiralty fire control table" there seems to be a fair bit of information about them online.  My father-in-law told me that on one ship he was on in the RCN his action station was at the wind input on an  admiralty fire control clock, this would likely have been on the Tribal class destroyer HMCS Nookta.
