The PRINZTRONIC SR99M is a small and nice calculator from the
nineteen-seventies. It has memory, a change-sign key, and the
square root function. The
RM key
pressed twice will clear
the calculator’s memory. When something non-zero is stored in the
memory it is indicated by the leftmost decimal dot on the display.
