Charles Babbage lives long enough to make functioning Meccano Difference Engines

do you know you can make functioning Difference Engines from the children's construction toy Meccano?

well suppose Charles Babbage never died of "of renal inadequacy, secondary to cystitis" and instead lived to be really really really old (like at least 110 years old) but his mind was still all there and some how in his dotage perhaps though a friends child or something he gets wind Meccano and thinks "hay those could be just the cheap standard parts I needed for my old failed in invention to work" then he and his son buy a howl load of Meccano and a few weeks latter "presto!" cheap mechanical computers invented by 1903, how will it change the world?
 
Babbage's Difference Engine was not a computer, but a mechanical calculator. It is his later design, the Analytical Engine, that would have been a Turing-complete computer. His Difference Engine had the sole purpose of calculating values of a polynomial. Inspired by his design, others built difference engines beginning in the 1850's; one was sold to the British government, and another was used to publish tables of logarithms.

The Meccano machine in the link is a toy compared to Babbage's Difference Engine, as it can evaluate quadratic polynomials using 4-digit numbers compared to Babbage's plans for 7th-order polynomials and 31-digit numbers. Babbage made a fragment of his Difference Engine of comparable size in 1832. The complete Difference Engine would have required hundreds of times more parts.

you can make a full size one as well, and what's more it would be really really cheap that was my point not that they would be really incredible that they would be really cheap,
