Casio Model 101-l.

This calculator is pretty rare with its red display.
Most of the calculators of this series have green VFD displays.

It is sold with its beautiful Casio cover.

Note that it is a 110v power supply.

If you need a wire, I will add it but, if not , please let me know as I have several other calculators and very few wires.

As it is 50 years old, I do not accept returns.
