 Grin So I'm in 9th grade right now and i have a ti84se. I downloaded zoommath500, and palyed around with it, found that it's really useful while it's way toooooooooooo expensive. Does anybody have any idea about how to hack that software, or move the cas from ti89, or the one in ti92, to z80 calc as a app or into it's system? it'll be hecka awesome

I don't think we'll want to crack the software.  (That would give us a bad reputation.)  You can check ticalc.org for math apps, and you can try those out.

It would not be easy, but I am sure it could be done. Once you get the design down for how to handle symbolic inputs, it should be relatively easy, though. Since the TI-92 and other similar calculators use a different processor (Motorola 68000), the software wouldn't make an easy port to Z80 Undecided

Spoiler for FileSyst:
FileSyst is an application that provides a folder and filesystem for the TI-83+/84+ calculators. It is designed to be easy to access and use in BASIC, and it can be used to access game files and save data, or to create a command prompt, among other things:

Spoiler for Graphiti:
This is a graph explorer for graph theory. It will require lots of work to finish. Currently you can:
Add/delete vertices
Add edges (direction not shown, but they are directed)
Arrange vertices in a circle (in the future, you will be able to define levels of rings and the number of nodes in each)
Create complete graphs quickly

Plans:
Add adjacency matrix viewer
Deleting edges
Multiple graphs support
Arrows for directed graphs
Planarity testing
Matrix operations
Weighted edges
Chromatic polynomials
Chromatic numbers

As already mentioned, gCAS2 would allow symbolic math processing, but it is still early in development and only on platforms that are setup for C, including the z80 running GlaßOS and linux.

AHelper, you can make SDCC progs for TIOS, they're just huge, and you need to modify the headers appropriately so they actually get recognized as programs, so unless it's a library problem I would think it would be portable.

(And we do know methods for hacking these things, by the way. It's just unethical, and rather unnecessary seeing as there are already free equivalents)

if i were you, i woud not talk about hacking stuff, this is an open forum, and you don't want the owners of it come in trouble because of this.

I'm not telling you not to do it, but try to keep those things of of the forums, thanks Smiley

i hope you'll understand

Hi welcome to Omnimaga. Nick is correct. Discussion about hacking software to allow free usage isn't allow here, so please keep that in mind. Moving a cas from the 68k series(The TI-89 and TI-92 calculator line) would be a massive undertaking as the processors that those calculators use are very different from what the Z80's (TI-83+s and TI-84+S) use. Not to mention that the CAS they use is probably under copyright as well. There are some alternatives available on ticalc.org, but I don't know how complete they are.

Here are a couple of programs you can check out for a start: Symbolic and Omnicalc There may be others as well. I'm not exactly a math guy, so some others may be able to direct you towards more programs that would suit your needs. Hope that helps. =) Oh, and don't forget to go Introduce yourself if you haven't already. Cheesy

Thank you guys very much and sorry for mentioning it xD
I just downloaded the apps your guys suggest me to, and i'm about to try them out.
And now i'm wandering if we can move some free cas stuff that's running on windows, since they're free and open source...no copyright or anything that touch the line of law...

so you mean writing your own cas, based on completely free pc version? those will need a total rewrite xs

and do you mean wandering like a wizard wand, or like walking around like a hobo? lol j/k

Yes, that would be quite fine. =) As nick said they would need to be rewritten for the calcs. though.

how far up in math are you? It would determine how much power you need.
