Ti-89 titanium diagnostics


There is no DiagnosticsOn command in the TI 89 Titanium. The command exists on the TI83/84PLUS where it displays the r and r^2 coefficients. On the TI89 , the correlation coefficient and the determination coefficient (r, r^2) are displayed by default among the statistics if THE REGRESSION MODEL includes them. If they are not defined by the regression model they will not be displayed. In short, you do not have to turn diagnostics ON.

Change TI 84 OS to TI 89 OS??


And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or amazon.com and spare your TI84PLus SE.

TI89 Titanium--main board replaced,must get its serial number


I am not sure if the number on the case is the one required. The TI89 Titanium and other recent TI machines have a unique ID. To get it, turn the calculator ON, Press F1 select 3: About.
On the subsequent screen, one finds various bits of information among which is a product ID and a 14 digit hexadecimal number ID ( a number in base 16, with Arabic digits 0 to 9, plus and A, B,C,D,E, and F)

The same number can be revealed by TIConnect software:
After machine is recognized, click TI Device Info. The Device ID is returned under General Information Tab or ID list tab.
This device ID could be the one needed for the Calculus Made Esay. software

I lost some of the stuff on my ti89 titanium because of a complete memory reset, how do i get them back?


It is hard though but there's a way, but the question is this, thus your calculator can be synchronized with computer?

If No...I'm so sorry there is no way

But if Yes...all you have to do is to have a data recovery software in your computer and that will do the job.

My ti89 titanium doesn't turn on


I had the same problem. I changed the batteries and it didn't work. I took out the batteries for about 30 minutes, and then put them back in, and it turned on.
