RPN programmable calculator; emulation of the Hewlett-Packard HP-42S. You can dowload an alpha here : Image:Free42.xo

An OLPC-optimized skin requires by-hand installation of skin files into a .sugar subdirectory at the moment; to be integrated into future bundles directly.

Note: existing "standard" or "realistic" calculator image (skin) appears inconveniently small on OLPC screen, but all keys, functions, etc are working.

Two new skins optimized for OLPC are working.

Project home site is http://free42.sourceforge.net/

Miscellaneous useful information here: http://mysite.verizon.net/vzesfls5/files/id10.html

1. OLPC skin files, how to install them, etc. 2. PDF Operating manual, RPN primer (document in development) 3. Linux TAR archive file containing both OLPC skins and the benchmark program 4. PDF benchmark program explanatory document. 5. Photos of Free42 running on the OLPC.

RPN in 25 words or less: "Give the calculator the numbers, then tell it what to do with them."
