What I saw demonstrated at the Science Museum (part of the British
Museum) 5 years ago was a working _difference_ engine. This had a
couple of design bugs fixed (one in the ripple carry mechanism IIRC) and
no printer.

I don't recall anything about an analytical engine being built at this
time. Has it been done since? Do tell!
