I am the author of Free42, a simulator for the Hewlett-Packard 42S scientific programmable RPN calculator. I am collaborating with Tom Schum to bring this simulator to the OLPC platform.
Free42 is already available for several other platforms; for more information, source code (released under GPLv2), etc., please take a look at the Free42 web site, http://free42.sourceforge.net/.
