Z80 calculators CAS project
« on: January 05, 2012, 05:49:13 pm »
 ;D 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 :/

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.
SDCC tastes like air bags - big output, but fast and safe to run.

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 :)

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: <a href=http://www.ticalc.org/archives/files/fileinfo/228/22851.html>Symbolic</a> and <a href=http://www.ticalc.org/archives/files/fileinfo/226/22626.html>Omnicalc</a> 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 <a href=http://www.omnimaga.org/index.php?board=10.0>Introduce yourself</a> if you haven't already. :D

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.

Or, you could learn the math. Your teacher will know if you don't!

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