- Description
- This handheld electronic calculator has a black and charcoal case and an array of eighteen black, white, and red "Klixon" keys. Such keys have a design trademarked by Texas Instruments and make a distinctive click when pressed. In addition to ten digit keys and one decimal point key, the calculator has four keys for arithmetic functions. One serves as a total key for addition and another as a difference key for subtraction. The top of the keyboard has a constant switch, a D key for recalling the display, a clear entry key, and a red clear key. The on/off switch is behind the clear key and the eight-digit red LED display behind this. A cord for recharging the battery attaches at the back of the top (this example has no cord).
- The back has four plastic feet (one is missing on this example). A paper sticker there gives operating instructions. Text near the bottom of it reads: RADIO SHACK MODEL EC-200 (/) SER. NO. A2 6411 (/) MADE IN U.S.A.
- Compare 1987.0435.25 (a Craig 4501), 1986.0988.84 (a Montgomery Ward P800) and 1986.0988.129 (a Bowmar 901B). This calculator is somewhat different, having two large screws in the back and a different style for the on/off switch. Unscrewing the screws allows one to change the four AA batteries.
- The Radio Shack EC-200 was introduced in 1973 at a price of $99.50. By April of 1974, it was on sale for $59.50.
