I'm having trouble finding a good HP49 rpn calculator emulator that works well on n810. It would be greatly appreciated if you could show me some links or information on the feasibility on getting a newer rpn calculator emulator working on a n810. Thanks.

Have you looked at Free42? It is an HP 42S emulator (non-graphing).

I've only found an HP48 emulator x48 http://yannbng.free.fr/Maemo/x48_0.4.3_armel.deb It is very slow, too slow to use. It would be great if someone could optimize the code for NIT's ( http://yannbng.free.fr/Maemo/x48-0.4.3_maemo.tar.gz ) . There is some talk about it in the Ti-89 emulator thread http://www.internettablettalk.com/fo...ht=hp48&page=2

I've looked at all the links that you have given me. I have the HP 42 installed on my n810 right now. I may be interested in contributing to that project. I guess I can contact someone for more information on that?

Well this guy made the deb and tarball above http://yannbng.free.fr It would be great if you could make x48 run faster on the maemo platform. Download the tarball and start playing with it.
