Posted Hide Post Yes,it was finally made in 1991.His plans contained a secret.There were two significant errors therein and the engine would never have worked were it built to them.He put the errors in deliberately lest anyone copied the plans. A thief could not make a working machine but Babbage could produce a working example and assert a patent. It wasn't built in his time, but only because he ran out of funds.
