Free42 HP-42S Calculator Simulator is an open source program designed to simulate this legendary scientific calculator introduced by Hewlett Packard in 1988. As such, it allows you to carry out all the mathematical operations you want with ease.
This program comes with two different versions of this calculator: binary and decimal. In addition, you'll also find two different skins at your disposal: a realistic one and the standard one. Another interesting option is that, like the original calculator itself, this version allows you to print your results. Of course, instead of actually printing them, what this means is that you can export them in GIF or text format.
Free42 HP-42S Calculator Simulator is a functional scientific calculator, thanks to which you can not only carry out any mathematical operation you can think of, but also do it with old-school style.
