Unisonic 767-1224 Desktop Electronic Calculator

This Japanese-made non-printing desktop electronic calculator has an array of nine digit keys with a zero bar and a decimal point key below. Immediately right of these is a column of four function keys. Right of these are a clear/clear entry key, a sign change key, a percentage key, and an equals key. Left of the digit keys are a power switch, a memory switch, a memory recall key, and a memory clear key.

Behind the keyboard is a twelve-digit display. The power adapter fits into the base of the machine, and has a plug extending from the back. A paper sticker on the base of the machine gives operating instructions. A mark just above the keyboard reads: Unisonic 767-1224. A paper sticker on the bottom gives instructions for operating the calculator. It is marked in part: MADE IN JAPAN. A mark on a sticker below this reads: NO. 04956. The number is written in pen.
