Who said analog computers need to have any moving parts? You're thinking
mechanical computer. AAMOF, analog computers use operational amplifiers
and different voltages to represent different numbers, i.e. 1-10 volts(it
starts at 1 instead of zero so that you can go below 0). They used two of
them at ground control during the early apollo missions for calculating
trajectory. TTYL!
