textbooks refer to babbage's differential machine, or even the eniac as the world's first computer. When I beg to differ, I cite the Antekythera (or however ya spell ti) mechanism. opens a few eyes as to just how smart we really can be.
ENIAC and Babbage's analytic engine (quite different from his differential engine) were programmable. Antikythera is not.
you make a point, but the AK's programmign is in it's very design - like a telephone - you can't program it, it's design is it's program - a single purpose unit.
