AFAIK, the operating one is a modern build of Babbage's design,
constructed with Babbage-era tolerances on the machining to see if it'd
work as designed.

It didn't - there was a small bug that Babbage would have fixed if he'd
ever got as far as building that much of his design. But they fixed
*that*, and now it works. All to Victorian tolerances, so I've heard,
and powered by a man winding a crank.

I've not heard that Babbage ever finished building any of his big
computer designs.
