National Semiconductor Novus 831 Handheld Electronic Calculator


This handheld electronic calculator has a tan plastic case with a tan and brown keyboard. Its capabilities are suited to student use, including not only the four functions of arithmetic but square roots, squares, and percentages. In addition to keys for these, the calculator has ten rectangular digit keys, a clear entry/clear key, a decimal point key, and a total key. The on/off switch is above these keys. Text above this reads: 831 NOVUS. Behind this is an eight-digit LED display. A jack for a power adapter is on the left side.

The battery compartment opens from the back.
