The Bowmar 901B, here with the OEM-label of Commodore Business Machines (CBM) was the first "True-Pocket-Size" calculator based on components of the Texas Instruments company. This calculator uses both the original Klixon™ keypad and the TMS0103 Integrated circuit. There is no doubt that the display was manufactured by Bowmar, known as LED manufacturer.

This calculator was sold under different labels, beside this Commodore C110 it was popular as Craig 4501, too.

Please notice the voltage selector on the original Commodore power supply to switch between 220 Volts and 240 Volts.

The next calculator in Commodore's line looks totally different, don't miss the odd Minuteman 1.

Klixon™ is a trademark of Texas Instruments.
