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