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.
The North American Foreign Trading Corporation of New York City, N.Y., first used the trademark Unisonic in 1968 for vacuum tubes, resistors and other electronic devices. In 1972 it extended the trademark to include calculators, receiving the registration in 1975.
