Description
A Texas Instruments Datamath TI-2500 portable electronic calculator accompanied by a mismatched retail box. The calculator is constructed with a beige moulded plastic housing and a black recessed faceplate. The interface consists of an 18-key keyboard with white and orange plastic keys and a slide switch for Chain and Constant modes. A red LED display window is positioned at the top of the faceplate. Markings on the faceplate include the Texas Instruments logo, featuring the state of Texas outline with the letters TI, and the model name Datamath. The lot includes a cardboard retail box for a Rever-so Clock Calculator, which is not original to the Texas Instruments unit. The box displays graphics of a blue folding LCD device.
