<p>I had to reset all the memory on my TI-89 for a big physics test (the teacher insisted) and now all my statistics programs are gone. Does anyone know how to get them back? Seeing as I'm taking AP Stat, they're pretty damn important, and I really don't want to have to use someone's crappy TI-83.</p>
<p>nope, sure don't. I don't even have a ti-89 and barely know how to operate my ti-83 :)</p>
<p>There are no ways to get them back. But you can always download again.</p>
<p>why didn't you borrow someone else's "crappy TI-83" for the physics test?</p>
<p>did you archive the programs? do you have a link to connect to the computer?</p>
