Free42 is a re-implementation of the HP-42S calculator and the HP-82240 printer.

This is a complete rewrite, not using any HP code, and it does not require an HP-42S ROM image. Free42 is an Open Source project. The executables and source code are released under the terms of the GNU General Public License, version 2. All third-party code used in Free42 is either in the public domain, or licensed under terms compatible with GPLv2, or used with the authors' permission. Different skins are also available.
What's New
Version 1.5.1:

Note: Version 1.5.1 requires OS X 10.6 or later, running in 64-bit mode. If you can't run 64-bit mode, or don't want to, stick with release 1.4.78 for now. That release still supports both modes. I intend to bring back support for 32-bit mode in 1.5 at a later date.

  • Fixed ASIN, ACOS, and ATAN so they return exact results in DEG and GRAD modes for trivial parameters (asin(1), asin(-1), acos(0), atan(1), atan(-1), atan(infinity).
  • Now displaying signed zero as zero, so you won't see -0 any more.

I never knew about this project and i must say: it is wonderful. Loading and saving programs from within the application , a very clear printview and many extras, for example the skins. I also miss the FIX ALL command on other emulation like hell, here it works like a charm. Many thanks to the devs! I use OS 10.8.2 and 10.6.8 - no problems here at all.
