Question about Texas Instruments TI-89 Calculator
You can interrupt the program by removing one of the main batteries. Put battery back in calculator and turn it on. You may have to adjust contast with [2nd] and [UpArrow] keys or [2nd] and [DownArrow] keys, pressed in sequence and repeatedly until contrast is adjusted.
Reset all Ram.
If you remove apps one at time, and let garbage collector work after each deletion of apps, it may run faster and will not hang.
Hope it helps
