Description
This handheld electronic calculator has a metal and plastic case with an array of nineteen square plastic keys. These include ten digit keys, a decimal point key, four arithmetic function keys, a total key, a clear key, a clear entry key, and a percentage key (the last is orange). A mark above the keys reads: Unisonic 1011. The on/off switch is right of this. Behind this is an eight-digit green vacuum fluorescent display. A jack for a power supply is along the back edge. A sticker on the back gives calculation examples. Text on it reads: SERIAL NO. (/) 042340 (/) MADE IN JAPAN. It also reads: 1011-A. Below this is a compartment for four AAA batteries.
