The National Semiconductor 600 Calculator

line
Accuron 600

This white colored National Semiconductor 600 calculator is a basic 6 digit RPN calculator.

The enter function is combined with the + function. The left slider switch selects between integer mode and a fixed 2 decimal point mode. This decimal point mode can only be used with addition and subtraction only!

This calculator looks very familiar with Accuron 600 and the Novus 650 matchbox. The only extra feature on this calculator is the decimal point switch.

 

This calculator can not be opened easily to check for the chipset used.

The operating instructions show that the + key is also used for ENTER.

The manual is just a small piece of paper with the instructions in three languages.
