^{*}Older versions of this calculator used 4 "AA" battery cells.
The SR10 is a truly ancient Texas Instruments calculator. It is one of the first "electronic sliderule" calculators, and predates the first true scientific calculators from this company. It does, however, have some scientific features, such as an exponential display and keys for calculating the reciprocal, square, and square root.
Like other fourfunction calculators, the SR10 doesn't belong to my collection of programmable calculators. Recently, however, I came into the possession of what appears to be a genuine SR10 prototype, as evidenced by the back label of this machine. I have since traded this calculator for another machine, but it deserves to be mentioned anyway due to its uniqueness.
