Casio √001 Desktop Calculator
The √Casio 001 is Casio's second
electronic calculator, introduced in January of 1966, preceded by the
Casio 001, introduced
three months prior. The √001 is visually
virtually identical to the 001, but adds an automatic square root
function. The same mechanical hardware is shared between the two machines,
with differences in the electronics to add the square root function.
The rest of the functions of the calculator are the same as with the
001. The knobs across the
front of the calculator can be set to provide a seven digit constant number
that could be recalled for repetitive use, for example, a discount
rate applied to numerous items. If you have one of these
calculators please contact us via the "EMail" link at the
