- Description
- This handheld electronic calculator has a dark brown plastic case, a cream-colored keyboard, and sixteen rounded rectangular plastic keys. In addition to ten digit keys and a decimal point key, it has a clear entry/clear key, and four arithmetic function keys. Pushing the divide and then the multiply key allows one to take square roots.
- Behind the keyboard is an eight-digit LED display. A mark behind the keyboard reads: Rockwell. A mark along the front edge reads: SQUARE ROOT 12R. The on/off switch is on the left side and the jack for a power adapter along the back edge.
- The back has a battery compartment at the top for a nine volt battery. A sticker below this gives operating examples. It also reads: Microelectronic Product Division (/) Rockwell International (/) Anaheim CA 92803 (Calculator Model 12R (/) Assembled in Mexico (/) U.S. and Foreign Parts. Further text reads: Ser. (/) No. 144332.
