Texas Instruments TI-2510 - Computer

In 1972, Texas Instruments began selling electronic calculators under its own name.
The first of these was the Datamath or TI-2500.
The handheld calculator has a ivory-colored case with a black keyboard.
It has an array of eighteen keys, sixteen of them square and two rectangular.
These include ten digit keys, a decimal point key, a total key, four arithmetic function keys, a clear entry key, and a clear key.
A switch at the right in the top row of keys may be set at “CHAIN” or “CONST.”
Behind the keyboard is an eight-digit LED display.
A jack for a power adapter is along the back edge.
An on/off switch is on the left side.


The calculator will be packed carefully.
