Question about Texas Instruments TI-89 Calculator
I was trying to load an assembly game on my calculator, the game started and then the screen said free up more RAM. I tried to exit and the screen went to the main apps menu and will not change. The cursor is frozen and taking out the batteries and putting them in had no effect. Everything is forzen except the clock which is still running. Please help in any way you can. thanks.
Well, not a long time ago I have had a similar trouble regarding to my Texas Instruments Calculator Voyage 200. It was forzen too doing some calculus. Also, one friend had a similar problem regarding to the fozen calculator... I fixed it by reading in the manual that it can be reset!!!...There is a combination of keys that you can press to reset the calculator...this obligates the calculator to load the OS from the EPROM memory where is this basic sofware!!!... If I do not remember wrong the keys are: 2nd + Lock + on/off keys!!! But try to look for the manual and in some part of it is those key combination!!! Good Luck!

For a long time, I was resetting my calculator (TI-89 Titanium) upon encountering an assembly-program error, by taking out all the alkaline (AAA) batteries, replacing them with a single, almost dead battery, taking out the backup battery, putting it back in place, and then putting the good alkaline batteries back in. Recently, however, I found out about another method, which is much less involved (for one thing, it doesn't require a screwdriver, unlike my previous method, for which one is required in order to remove the battery cover for the backup battery, as the battery cover is screwed down). After some searching, I found in TI's official guidebook for my calculator (Part 2, the electronic version of the guidebook) where it says exactly what to do if the "TI-89 Titanium appears to be 'locked up' and will not respond to keyboard input. "The following action clears RAM. This erases all [unarchived] data, programs, and user-defined variables, functions, or folders. "Press and hold [left arrow key], [right arrow key], and [Second key]. Then press and release [ON]. "The following action clears RAM _and_ Flash ROM. This erases all data, programs, user-defined variables, functions, folders, Flash applications, and the user data archive. "1. Remove one of the four AAA batteries. "2. Press and hold [(-)] and [)] as you reinstall the battery. "3. Continue holding [(-)] and [)] for five seconds before releasing." (From page 952 in Appendix B: Technical Reference)
