- Description
- This handheld electronic calculator has a black and silver-colored plastic case and an array of nineteen rectangular plastic keys on a metallic-colored keyboard. It has ten digit keys, a decimal point key, a total key, four arithmetic function keys, a clear/clear entry key, a memory key, and a percentage key. The on/off switch is at the far right on the top row of keys. Text behind the keyboard reads: Unisonic 940. Behind this is an eight-digit green vacuum fluorescent display.
- A jack for a power supply is on the right side.
- A compartment for three AAA batteries is on the back. A sticker above this gives calculation examples. Text here reads in part: 940-A. It also reads: SERIAL NO. (/) 03885 (/) MADE IN JAPAN. The name “JOHN” is scratched in the plastic on the back of the calculator.
- Compare the Unisonic 940 (1986.0988.319). The two calculators have cases and keys of somewhat different colors.
