 for good introductions, all analog computer are
 basically the same, the biggest difference is how many
 op amps they have, and that limits what you can do. 
While that's true for most modern *electronic* analog(ue) computers,
it's not a good generalisation.  What about things like Vannevar Bush's
differential analysers, gun directors, Norden bombsights, various
electro-pneumatic or hydraulic computers, or the G-star analog
"computer" used by CalTech at Mt Palomar?

I seem to be in pedant mode today (as Ethan's discovered, possibly) and
I couldn't resist pointing out some alternatives :-)
