The GE 210 Computer announced in 1960 was based on the earlier ERMA (Electronic Recording Machine Accounting) system developed in the early 1950’s. ERMA systems used MICR (magnetic ink Character recognition) which revolutionized bank check processing. At least 44 systems were produced from 1960 to 1964.
