42S is a Windows Phone port of Thomas Okken's excellent Free42, a complete re-implementation of the highly praised HP-42S RPN scientific calculator. Thomas' original code was written from scratch, without using any HP code or using any ROM images, yet it is fully HP-42S compatible. This calculator provides all the functionality of the original HP-42S including several hundred built-in functions, extensive programmability, and printer output emulation.
