content: This handheld electronic calculator was described by its vendor as the “Sears Electronic Slide Rule.” It has an array of twenty-five sloping plastic keys. These may either perform the function indicated on the key or, if the f key is pressed first, perform a “secondary function” which is indicated above the key on the keyboard. With this combination of keys, the calculator performs not only the four arithmetic functions but computes natural and common logarithms and anti-logarithms, trigonometric and inverse trigonometric functions, square roots, roots, powers for any real numbers, and reciprocals. The number pi may be recalled and there are five memory keys. An on/off switch and a degree/radian switch are behind the keyboard. A mark behind them reads: Sears Electronic Slide Rule. Behind this is an eight-digit fluorescent display with a sign indicator.
