The add-lister type of machine is much slower in use than the "Comptometer" type of machine since the handle has to be pulled forward to add (or subtract) each number entered - though you do have a printed record of all calculations which can be useful for checking later. Michael Hancock has produced an interesting history of the Burroughs Adding Machine Company and its calculators at http://www.xnumber.com/xnumber/hancock7.htm. |
