    How big was the difference engine?
    Difference Engine No. 1 is the first complete design for an automatic calculating engine. From time to time Babbage changed the capacity of the Engine. The 1830 design shows a machine calculating with sixteen digits and six orders of difference. The Engine called for some 25,000 parts shared equally between the calculating section and the printer.

    May 27, 2022 · But Babbage, perhaps reinvigorated by his work on the Analytical Engine, decided to return to the Difference Engine in 1846. Difference Engine No. 2 required only 8,000 parts and had a much more elegant and efficient design. He estimated it would weigh 5 tons and measure 11 feet long and 7 feet high.
