A simple LED display scientific RPN calculator made by National Semiconductors. This calculator is not programmable and has no exponential mode, it can also not display in exponential notation.
A remarkable feature of this calculator is the M+x2 function printed below the MS key. Some examples in the manual demonstrate the benefit of this function for adding the square of the number to calculate the area of a cone and for conversion from rectangle coordinates to polar coordinates.
