Free42 is a re-implementation of the HP-42S calculator and the HP-82240 printer.
It is a complete rewrite, not using any HP code, and it does not require an HP-42S ROM image.
Free42 Binary uses each platform's native floating-point support. On PCs and Macs, this means the hardware FPU, while on hand-helds, it usually means FPU emulation or a floating point library.
Free42 is an Open Source project. The executables and source code are released under the terms of the GNU General Public License, version 2.
