The 101 was also the first formally exported Casio electronic calculator, with the first batch of machines exported to Australia, which were sold there under the Remington brand name. 10-digit, four-function, fixed or floating decimal. Accumulator-style memory register. Follow-on to Casio first-generation calculators based on Germanium transistors, the 001 and Root 001 calculators. Knobs on front of the calculator are for setting decimal point location and a seven digit constant value.
