National Semiconductor Novus 750

This recent addition to the calculator collection was manufactured in about 1976 and has a very pleasing 1970s beige and brown look. The calculator supports the four arithmetic functions only though displays numbers with a lovely red LED display.

The calculator does turn on though is pretty flakey. The slightest movement can clear the display. Like many calculators of this vintage the logic of the CPU seems to have suffered bit rot. It can display entered numbers but not really do anything with them.
