Example of a Summit calculator
A typical chunky calculator from Summit. There is not enough room on the front for some of the buttons so these have been added to the top edge. This model dates from about 1972.
This is a featured calculator.
For further photographs of Summit hand-held calculators see the Calculator Photo Library on this site.
