Description
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.
What’s New
Version 3.2.3
Added a few characters to the character set, in order to allow copying and pasting text between Free42 and Plus42 without losing information.
Implemented Swipe to Delete in the file selector dialog.
Ratings and Reviews
Works great
Wish there was a 41 CV version to replace my real one. But this is a good replacement.
Developer Response ,
I'm glad you like Free42, but if you're specifically looking for an HP-41CV or CX emulator, i41CX is a good option.
RPN Rules
My physical HP calculator died after 36 years and like many old engineers (I suspect), I wouldn’t use anything else. I tutor high school kids, with their TI 83’s and 84’s. Even though they can text much faster than me, an RPN calculator runs circles around them.
This app is a perfect replica and I urge anyone who is allowed to use an iPhone to try it. It takes about 20 minutes to get used to a completely different way of operating, but you won’t ever go back to algebraic entry.
Very Nice
Works like it should!
Great tool & good fun to use.
Thank you
