Texet 1

Display is 8 digits, red LED.

Four functions.

Main integrated circuit - Texas Instruments TMS1802 (here date coded week 7, 1972).

9v (6x AA batteries).

79 x 151 x 38 mm (3.1" x 5.9" x 1.5").

This calculator is a little unusual for two reasons:
Firstly it employs the first "calculator-on-a-chip" manufactured by Texas Instruments, the TMS 1802.
Secondly, it has features of an early low-volume calculator before mass production took over. It is solidly made with a metallic body, "Klixon" keyboard, uses shaped pieces of phenolic plastic, and has a very unusual multi-pin socket for the external power supply.

This is a featured calculator in the Hand-held Eletronic Calculators section.
