If the captions on the pictures (very nice, by the way) are correct, this
simulator isn't an analog computer at all by the definition I'm familiar
with. It uses tubes and relays, which are discrete digital components
(they're either on or off, with no states in between). An analog computer
as I understand it is something like a differential analyser, which uses
rollers and turntables which have (virtually) infinite states, depending on
how finely you can measure. Another example of an analog device would be a
slide rule.
