Commodore Minuteman 2 Handheld Electronic Calculator

Description
This handheld electronic calculator has a white case with black trim and metal keyboard, and an array of square black "Klixon" keys. Such keys have a design trademarked by Texas Instruments and make a distinctive click when pressed. In addition to ten digit and one decimal point key, the calculator has four keys for arithmetic functions. One serves as a total key for addition, another as a difference key for subtraction. The top of the keyboard has a constant switch, a clear entry key, and a red clear key. The on/off switch is below the keyboard. The text next to it reads: commodore (/) Minuteman 2.
The eight-digit red LED display is behind the keyboard. A cord for recharging the battery attaches at the back of the top. (This example has no cord.)
The back has four plastic feet. A metal plate there gives operating instructions. Text near the bottom reads: COMMODORE (/) MODEL MM-2 SER. NO. R216527 (/) SANTA CLARA, CALIFORNIA (/) MADE IN U.S.A.
This was one of the first models of a handheld calculator sold by Commodore. It was manufactured by Bowmar/Ali and is similar to the Bowmar 901B.
