Commodore Minuteman 6 Handheld Electronic Calculator

Description
This small four-function calculator is wedge-shaped, inclining toward the front. It has fourteen oval keys and an oval zero bar. In addition to the ten digits, these allow for the four arithmetic operations and clearing (but not clear entry). Each arithmetic function key serves as an enter key for the corresponding operation (e.g. pushing the appropriate key gives the product, result, difference, quotient, or sum). The calculator has a six-digit red LED display.
A mark between the keyboard and the display reads: commodore. A switch on the back edge allows one to set the display to read dollars and cents (there is no decimal point key).
The battery compartment at the top of the back would hold a nine-volt battery. A sticker in front of it reads: MINUTEMAN * 6 (/) VOLTAGE 9V CURRENT 0.08A (/) SERIAL NO. 377139 (/) MADE IN U.S.A.
