I wouldn't be so quick to do so. The prior post notwithstanding, while it's
possible to use some tubes as bipolar devices there were certainly all sorts of
analog computers that used tubes as voltage amps, op amps and comparators.
If forced to classify (based on vintage, application and technology) this beast
as analog, digital or hybred I'd certainly call it analog.

If the captions on the pictures (very nice, by
the way) are correct, this
Thanks.
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.
Hmmm. I guess you'd be right. I just may have to update those pages. :)
