Novus 4510 Mathematician
The Novus 4510 Mathematician calculator has an eight-digit red LED display and is powered by a 9-volt battery. It has a off-white case with a matte black keyboard label that has silver trim. It has an on/off switch on the left side near the top and a jack for an AC adapter on the top right side. This machine was also known as the National Semiconductor Mathematician and the Novus 4510. Novus was simply another name National Semiconductor used to market their calculators.
The Mathematician is a basic scientific calculator. Like the machines from Hewlett-Packard, the Mathematician uses Reverse-Polish Notation (RPN) for calculation, however, as a low-cost unit it only provides a 3-level stack, and the top register is not copied downward when the stack drops as it is on the HPs. The machine's display is limited to eight digits and does not support either scientific notation or overflow - if the result of a calculation exceeds 99999999 the machine simply displays all it's decimal points and all "0"s. The machine has an automatic power-down mode that lights only the decimal points after a period of inactivity.
