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 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.

From version Free42 3.0.7:

A2LINE now handles strings that start with characters 127-255 better. Also, added A2+LINE function for generating appended strings.

More accurate complex TAN and TANH.

RND did not handle large numbers correctly, failing to round off as many digits as necessary in certain cases. Fixed.

Σ+ and Σ- always wanted two arguments, even in NSTK mode, when X contained a real matrix. Fixed.

Copy and Paste now handle list objects.
