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
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.
