Ah but this was never run and th ehardware never built, admittedly a
pedantic point.

This is new to me, thanks for the reference and link.

I think you might be confusing Babbage's difference engine and
analytical engine. A working version of the difference engine was built
by the Londoen Science Musuem in the 90's. An excellent description is
provided by Doron Swade in his book The Cogwheel Brain (ISBN
0316648477). It was the anlytical engine which resembles a modern
computer and, to my knowledge, no one has attempted to construct one of
those (yet ;-).
