Transfer Titanium OS to TI-89
Hi, I was trying to solve inequalities on my regular TI-89 today and discovered I couldn't!
I did solve((x+6)(x-2)>8,x) and pressed enter. Instead of the answer it just spit me back the question. I tried on 2 different TI-89 Titaniums and it worked fine. I called TI tech support and they said it must be a limit of the old 89 operating system.
Is there anyway to get the Titanium OS onto my regular TI-89 (preferably through the internet)? And where would I buy a cord compatible with a regular TI-89? Also, it says I need to download something in order to use FlashApps...
