Bowmar introduced a calculator in 1971, and had successful sales in 1972 and 1973. Assembly began in Mexico in mid-1974. The company went bankrupt in February of 1975 and stopped building calculators in the middle of that year. By 1976 distribution of Bowmar calculators had been taken over by Continental Microsystems.
