MR. BOOKKEEPER, do you know what the Comptometer is? It costs you nothing to find out. It will help you out on that trial balance. It insures accuracy, is twice as rapid as the best accountant and relieves all nervous and mental strain.

    I used one of those at a lumberyard where i worked in the late ’70s, I still had nervous strain, didn’t like fooling with the books.

    they still had schools to teach people how to use these things in 1963 – ask me how I know!I used one in an accounting office as late as 1972.
