Hi, I was, earlier today, deleting some unused flash applications from my Ti-89 Titanium that were wasting space. Namely the localization things like Cabri Deutsch and Francais and stuff. After setting it to delete a few files, my Ti-explorer on my computer stopped responding, and and so did the calculator. I thought it was just taking a while to perform the action so I left for a piano lesson, but after a three hours, nothing had changed. My computer still wouldn't respond and neither would my calculator. After that I pulled the USB plug out, and the calculator just went dead. Best Rhinestone Software. Yea, I realize maybe that was a stupid move; however, I tried breaking and resetting the calculator and nothing worked; I couldn't shut down the computer either.

I had a backup on my computer of the files I deleted in case they would cause problems once deleted, but I can't restore them because I can't turn the calculator on now, and thus can't connect it to my computer. I would appreciate if someone can help me with this. Download Countax A2050he Manual.

It is possible to create your own personal toolbar at the top of your TI-89 where you can place whatever programs and/or functions.

Uh yea this is solved already, I called support and they told me how to reset everything the calculator. Then I just had to install the OS again and it worked. It has nothing to do with computer problems; the calculator just had some glitches deep down and needed a complete reset (not just the reset thing from hitting second + on + left + right). Ti89 has an inherent text creator, and you can transfer that to your pc. I'm not sure if you can transfer text files from your pc to the calculator and get it to open, though. HP50 has inherent RPN so I would get that.

The Ti-89 has a program you can download to use RPN but meh, HP50 >that. The only reason I got the Ti-89 was because more people use Ti stuff, and thus, there are more programs for it.
