Features & Capabilities

Simulator for the HP 15C "Programmer's" calculator.

Scientific calculator that simulates an HP-15C. It simulates the appearance and behavior of the original, including the seven-segment display, and the little blink you get when entering numbers. Includes complex math, matrices, numerical integration, solving for the root of an equation and statistics. Very state of the art for 1982!

User Reviews

An easy to use RPN calculator is very helpful in my tax work as a CPA. Excellent rendering of the original HP 15C.

Use it regularly, powerful and compact. I prefer the horizontal layout as it matches the original device. Recommended.

Far superior than the one offered by MORAVIA consulting!
