Babbage Difference Engine No.2
Charles Babbage was not able to raised the funds to build a complete Difference Engine. 153 years after he died the first working engine was completed at the Science Museum in London. There is now a second in Mountain View, California.
It had many of the attributes of a modern computer - separate CPU, memory and I/O devices, stored programs and easily reprogrammable with punched cards.
