Question about Texas Instruments TI-89 Calculator

1 Answer

TI-89 Problem I had to reset my ram memory on my TI-89 Calc. but afterwards many of my apps were permanently deleted. Now I need to re-install the programs onto my calculator, but the TI connect software does not recognize my device, thus I cannot download any new programs on my TI-89. I have been working for hours now and I cannot find a solution. Is there a solution that will allow TI connect to reconize my device?

We have a TI-89 and it is froze on the home page. we tried holding the 2nd button , left arrow , rigth arrow and pressing the on button. it comes up with installation in progress , but when that is done it...


Here is a procedure to reset the TI-89 to factory settings (found online):

  • Press the "Snd Mem" key to display the memory screen.
  • Press the "F1" key.
  • Press the navigation key to select the "RAM" icon, then select "1: All RAM" to erase all data and programs from the random access memory and press the "Enter" key, or select "2: Default" and press the "Enter" key to reset all system variables to original factory settings. This preserves any user-defined variables, functions and folders.
  • Press the navigation key to select the "Flash ROM" icon, then select "1: Archive" and press the "Enter" key to erase all data and programs from the read-only memory or select "2: Flash Apps," then press the "Enter" key to erase all applications from the Flash ROM. Select the "All Memory" icon and press the "Enter" key to erase all data, programs and flash applications from the RAM and Flash ROM.

  • Hope this helps.

    My TI-89 calculators finance app is giving me the wrong answers by a few 1000 or so and increases how far off it is the larger the figure

    Make sure your decimals are set to the correct number.
    And also you can perform a factory reset on the unit to make sure all is back to normal.
    Just be aware that it will delete any information which you have stored into your calc.

    After using the TI-89 and changing modes several times, you may set the calculator back
    to all default modes by pressing 2nd 6 (MEM), F1(Reset) and 3 or by highlighting
    3:Default and pressing ENTER. To reset all memory press 2nd, 6 (MEM) then F1(Reset)
    and select 1: All.

    I need to reset my TI-89 Titanium

    There is several ways to reset the Ti-89 Titanium calculator. Other than the one shown to you by K24674, just hit [2nd] [MEM] [F1] instead of [diamond] [MEM] [F1], then:
    Press [1:RAM] then select [1: All RAM] or [2: Defaults] and [ENTER] to reset the RAM.
    Since you didn't give him four thumbs up because, he did what you stated. I'll tell you other ways to do a reset. The reason is because, you may have a locked up calculator that seems impossible to reset.

    Push [2nd] [MEM] then [F1] [3] [ENTER] for yes to reset everything.

    If your have downloaded 3rd party shells, games and programs and your calculator is locked up, you may need to take out all the batteries including the small circular one for about 4 hours or more.

    If this doesn't work you will have to deal with it, possibly by deleting out what you can to free the calculator up to start operating properly, and re-installing the OS software.

    Actually most people don't even need to reset their calculator memory. It is usually just a single variable that their using that is what hanging them up. Just execute the NewProb command to delete all single variables in the folder that your working in by pushing [2nd] [F1] [2] [ENTER]. This only deletes single variables a to z. This method is unlikely to miss you up with other programs, functions that are not archived or can be mistakenly deleted on your calculator. Works real good while working out of the main folder. Hope this helps you!

    Can you delete ram with ti connect?

    This is your question which I think is the solution for this question!

    I downloaded Mirage OS, and now I can't download any of the games. I downloaded tetris before, and then I came back and can't download anything through TI connect.

    Obviously, at times ti connect is going to be worthless to you if you have OS Mirage. So, that's correct! Plus, it didn't cost me a calculator to find that out!

    For you to get it off? I can think of a few, I glad I don't have too..

    How do you restore a TI-89 Titanium clac

    Perhaps one of the following sources will be helpful:

    To reset the TI-89 family, TI-92 family and Voyage 200 graphing calculators, press [2nd] [6] (reads MEM over the key). The [F1] menu appears and contains the following options:
    • All RAM - Clears all variables and programs from RAM only. This will not delete items from Archive or Apps.
    • Defaults - Does not clear any files from the calculator. Instead, this option resets the calculator settings to default, including the Mode, Graph Format, Table Setup, and other settings.
    • Vars - Clears all variables from Archive (Flash ROM). This option will NOT delete Apps or variables stored in RAM memory.
    • Apps - Clears all Apps from Archive. This will not delete any variables.
    • Both - Will clear all Apps and Variables from Archive. This will not delete any Variables from RAM.
    • All Memory - Clears everything from RAM and Archive, leaving only the Calculator OS and its components.
    For example, I think you will want to follow the last step above... which would be to press [2nd] [6] [F1] [1] [1] [ENTER] [ENTER].

    Also, if you are looking to clear all the RAM in another way I would take a look at the guidebook, which is downloadable from the following site in PDF format.

    Take a look at page 951 and 952 for another way to clear the RAM

    Garbage collect error on a ti 89 Titanium calculator. The problem is, is that I cant archive what needs to be archived so that it wont be deleted when I garbage collect to free up space

    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
