Texas Instruments TI-1500 Handheld Electronic Calculator
Texas Instruments TI-1500 Handheld Electronic Calculator
- Description
- This handheld electronic calculator has a black plastic case with metal trim around the edge. It has an array of nineteen square plastic keys. This includes ten digit keys (all but the zero key white). It also has a decimal point key, a total key, four arithmetic function keys, a clear key, a clear entry key, and a percentage key. The on/off switch is at the top left of the keyboard.
- A mark above keyboard on the right reads: TEXAS INSTRUMENTS. Behind the keyboard is an eight-digit LED display.
- A jack for a power outlet is along the back edge. A sticker on the back reads: TI-1500 electronic calculator (/) Texas Instruments Incorporated. It also reads in part: Serial number (/) 1500 256747. The sticker indicates that the calculator should be recharged using an AC9140 adapter/charger. A mark scratched on the side of the calculator reads: NAU (/) 068499.
- The TI-1500 was the successor to TI’s 2500 Datamath series of calculators, and hence early in the history of the company as a producer of electronic calculators. The online Datamath Museum describes three forms of the TI-1500—this is the third form. It dates a calculator of this model with serial number 1500 219114 to the spring of 1976.
