I did run TiEmu a long time ago, I think it was probably a Zaurus port. It was very memory hungry and slow (pretty much the same comments as for the Zaurus port: http://www.oesf.org/forum/index.php?...2&#entry118082)

It might work better if you try building it to use hardfloat (though I'm not sure how much of an advantage that would give to the emulator), but it's a bit of a pain as you need to build all the deps too - libticables, libticalcs, libticonv, libtifiles and finally tiemu (I built it for the 770 - it was a long time ago - but there was some problem with the binary iirc and as it wasn't likely to be much faster I filed it away and got on with other things).

I'm actually after the same sort of thing, and eventually decided to build my own (http://people.bath.ac.uk/enpsgp/nokia770/pycalc.html). My apologies the page is only half done (like the program ), I'll put the download urls in and some screenshots asap. This doesn't do graphing, just provides a GUI for a backend (yacas atm), but there are Python graphing packages (e.g. matplotlib), which I was planning to add in too.
