content: This hefty turquoise handheld electronic calculator has a plastic case, keyboard, keys, and screen.It fits in a black plastic, cloth-lined, zippered sleeve. It has an array of ten digit keys with a decimal point key, four keys for arithmetic operations, a total key right of these, a clear key, and a percentage key. A red button above the 7 key apparently allows one to switch between floating point arithmetic and dollars and cents. Above the keys are an on/off switch and a switch between the AC adapter and the battery. (The example presently has no adapter and no battery.) Behind this is an eight-digit green-tube display. A mark behind the display reads: Bohn Instant. On the back is a two-prong plug for an adapter. The back has two plastic feet and, at the base, a compartment that would hold five batteries.
