The 1201 was the entry-level calculator in Singer/Friden's 1200-Series of calculators. The 1200-Series calculators were a departure from Singer/Friden's earlier use of calculators made in Japan by Hitachi (the 111X-Series). The 1200-Series machines were made in the USA using US-manufactured parts. The 1201 was a twelve digit, five function (+, -, X, ÷ %) machine with a single accumulator-style memory register. There were two other machines in the 1200-Series, including the 1202, and the Friden 1203. These machines all utilized Large Scale Integration circuit technology made by Rockwell and Burroughs Panaplex II displays.
