<<Addiator is the trade name of the company which manufactured very popular, small, hand-held mechanical calculators of the same name. In the same way that "hoover" has become synonymous with vacuum cleaner, so "Addiator" became synonymous with this type of calculator. On this page are examples of true Addiators and models from other manufacturers.>> Received on Mon Feb 05 21:00:00 2007
