The
Bowmar 901B, here with the OEM-label of Craig Cooperation Machines 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 Craig
4501 it was popular as
Commodore C110, too.
Don't miss the later Craig 4510 manufactured by a Japanese company, but nevertheless "very Texas Instruments".
Klixon™ is a trademark of Texas Instruments.
