Bowmar Instruments,
a giant manufacturer of calculators like the famous 901B,
was one of the first casualties of the Calculator
Wars and filed in 1976 for bankruptcy.
It is still a mystery what company placed such a great name on one of the
cheapest calculators of the 70s!
Within the Datamath Calculator Museum we refer this calculator as Far East Generic
Design I.
Dismantling
this Bowmar calculator manufactured in December 1977 reveals the expected
printed circuit board (PCB) centered around a Texas Instruments
TMS0972
single-chip calculator circuit introduced with the TI-1250.
