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, an exchange key, four arithmetic function keys, a total key, a clear key, and a clear entry key. It does not include such common slide rule functions as square roots or trigonometric functions.
A mark behind the keyboard reads: Unisonic 1212 (/) SLIDE RULETTE. Behind this is a green vacuum fluorescent display. A switch and a jack for a power supply are along the back edge. Text on the back reads: Unisonic 1212 (/) RATING 6V-DC 0.6W (/) NO. 046435 (/) MADE IN JAPAN. The digits of the serial number are very difficult to read. Below this is a compartment for four AA batteries.
