Look around on YouTube. There's some fascinating videos from the 1950s on US Navy mechanical firing computers.
These machines can calculate ballistic trajectories with incredible accuracy, accounting for the relative motion of the ships, wind speed, and even the curvature of the earth. Those calculations are not at all trivial!
