Simply fast and immediate as the original! You have to like RPN, that said it's a perfect everyday's tool. I normally associate it to a fast launch key from desktop, both on WIndows and Linux

What is Free42?

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.
