TiEmu on N800?
 

Hello everyone,

First post here and I would like to thank the community for being helpful in my research.

I'm considering getting an N800 and was wondering if there is a calculator app with calculus and graphing capabilities. More specifically, I'm interested in knowing if anyone has successfully ran TiEmu (a Ti-89 emulator, see http://en.wikipedia.org/wiki/TiEmu) on it. I understand Mathomatic and yacas work well enough but both seem to lack graphing abilities, hence my interest in TiEmu.

Can anyone help? :)

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.

wxMaxima would be a pretty easy port since wx has some basic Hildon support, IIRC.

Ah, that does look interesting as it appears to do pretty printing.

Thanks for the pointer.

As i remember there is no wxWidget port for maemo.

Thanks for all the responses guys.

lardman:
I think I will hold off my N800 purchase in favor of the N810 as I'm thinking that maybe the faster processor may offset any performance deficiencies of TiEmu on the N-series. This is, of course, assuming I'll be able to successfully build it for the N810 in the first place. If worst comes to worst, I may end up running TiEmu on my Ubuntu box and accessing it through the N810 via VNC, if possible at all. Nevertheless, I'll be keeping an eye on your project as you develop your calculator.

aleksandyr:
Thanks for the suggestion. I'll definitely look into wxMaxima.

Thanks again everyone :)

I'd get the N810 anyway, but the extra speed won't make much difference.

It's not too bad to build, I've got it sat here in front of me - I should do a proper debian build though as the only hand crafted .deb I had was lost on one of my SD cards. Give me a shout once you have an N810 and a build system setup if you need any help.

It still strikes me as a waste of resources though, there are decent symbolic algebra programs out there (e.g. yacas, maxima) and there are ways to do graphing - it's just combining the two in a nice package.

Also take a look at xcas/giac - I've built this but the binary segfaults for some reason. I'll give it a go with Chinook when I get my N810/N800 upgrade and see if things have changed.

Re: TiEmu on N800?
 

Thanks for the prompt response lardman.

I'll make sure to get in touch once the N810 arrives and run into any TiEmu issues, but you are probably correct about no difference in performance despite a faster proc.

This is the direction I'm heading the more I'm learning about what's available for the N-series. I will most likely be running separate apps to achieve my aim, unless something else comes along that integrates all functionalities. I definitely will look into xcas/giac.

Thanks again.

While I'm on the subject, something like this: http://qalculate.sourceforge.net/

would be pretty cool - it automatically sorts out unit conversion and keeps track of units.

It would be nice to produce a nice integrated frontend for all these different programs (a bit like the Ti with its selection screen).

P.S. The N800 and N810 have the same processor, the N800 will be the same speed as the N810 with the new OS2008 release

Re: TiEmu on N800?
 

Woah, that really is nice. That little input window would seem a perfect fit for the display size.

Really? I thought the proc was the same but with a 70MHz difference (330 vs. 400 MHz), but now I'm not so sure. I got my source from wikipedia so maybe the tech specs aren't up to date.

Re: TiEmu on N800?
 

The processor on the N800 is underclocked prior to OS2008, for reasons of battery life.

Apparently in OS2008, they made enough improvements to power management that they "unlock" the full clock rate of the processor without a noticeable difference in battery life compared to previously versions.

Re: TiEmu on N800?
 

Wow, that's news to me. At half the price this seems to give the N800 a little more bang for the buck if it operates at the same speed. But I like the latest and greatest gadgets so I will most likely end up with the N810 :D
