Re-implementation of HP-42S calculator and HP-82240 printer.

Overview

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 in Free42

Version 2.0.23:
  • SOLVE now tries harder when secant extrapolation gets stuck due to the secant being excessively steep.
  • 0^0 now returns Invalid Data, not 1, for all combinations of real and complex arguments. The rationale for returning 1 was mathematically questionable, and Invalid Data is what the real HP-42S returns.
  • iPhone version: added basic iPhone X support.

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.
