Jefferson Handheld Electronic Calculator
Jefferson Handheld Electronic Calculator
- Description
- This simple calculator has a black plastic case, a flat keypad with ten digit keys, a clear key, four arithmetic function keys, three blank keys, and an on/off switch. Behind the keyboard is a six-digit red LED display. A sticker behind this reads: Jefferson. The back has a sticker with operating instructions, which is marked at the bottom: Made in U. S. A. The battery fits at the top of the back. A mark on the circuit board inside the case reads: PCB - 676.
- It seems likely that Jefferson sold rather than actually manufacturing the calculator.
