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
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
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
