Uploading programs to a TI-89 Titanium

I recently purchased the TI-89 software "Every Step Calculus" to help me out with a few things in my courses.  In order to make it easier for others to install the Calc 1 alongside the Calc 2 & 3 packages, I am making this tutorial.  First, I'll start out with how to do it in Windows, and then further down how to do it in Ubuntu Linux.

A short note: You will be transferring these files to the Archive portion of memory on your calculator.  In short, it will be slower than putting them in RAM.  Think of it this way: on your computer, files are stored on the hard drive.  When you want to run a program you must call it from your hard drive and put it into RAM (much faster, but not as big), allowing it to run.  The same goes for your TI-89.  However, if you can deal with waiting a couple of extra seconds, you will have many more programs available at your fingertips than the alternate method of loading only Calc I or Calc II/III in RAM.

Windows:
Clear the memory on your calculator: [2nd] [6] [F1] [3] [Enter]
Install TI-Connect
Connect your TI-89 to your computer via the supplied USB cord
Open TI-Connect and select Send to TI Device:
It will open the appropriate window:
Click Select Device.  It will scan for your calculator
Once found, select USB 1:

Now, click Browse on the main window and navigate to your Calc I folder.  Select all contents and click Open:
Change each entry, line by line, from RAM to Archive:
It should end up something like this:

Now, click Send to Device
Repeat the above steps for your Calc 2&3 folder.  Remember to change it from RAM to archive on each line.
Now you will be able to call up any program from Calc 1 by typing index8() or 2 and 3 by typing index9() without having to clear your memory and re-sync your calculator.  Enjoy!


Ubuntu Linux:
(I won't be doing screenshots... if you are a linux person that enjoys screenshots, please comment below and I will update my entry)
  1. Clear the memory on your calculator: [2nd] [6] [F1] [3] [Enter]
  2. Download TiLP2 from the Software Center, Synaptic Package Manager, or from here.  There are a couple libraries that you will need (libusb and usbfs) if you download it directly from the web site, which is why I recommend to just use your package manager to satisfy all dependencies
  3. Plug in the USB cable and turn on your calculator
  4. In terminal, run sudo tilp
    1. There is a known issue with access to the libraries being denied if trying to connect via your USB cable.  I've tried it, and get the following message: "Msg: failed to open the USB device. Cause: Check that the USB cable is plugged in and that the calculator is turned ON! Also, check libusb and usbfs for valid permissions".
    2. I suppose I could change those permissions, but I haven't yet, and running from terminal doesn't bother me since it opens the GUI anyways
  5. If it opens with errors, ensure the cable is connected, it is turned on, and that you have the correct libraries (See step 1)
  6. Click the Refresh button to display your calculator's contents in the left pane
    1. If this step does not display your contents, go to File > Change Device, Click the magnifying glass to scan for your device, select what it finds in the bottom window, and click OK.  Then, click Refresh to display the contents.
  7. In the left pane, click the arrow beside Variables to minimize it
  8. In the right pane, navigate to your Calc I folder
  9. Click and drag every file over (yes, you have to do it one by one... ugh) to the Applications in the left pane.  This step will put them in Archive.  Putting them in Main will fill up your RAM and everything will not fit.
  10. Once completed, navigate to your Calc 2&3 folder in the right pane, and repeat the dragging process.
If you do not want to drag over everything, or if you think you messed up, at a minimum take the index8 / index9 as this is the main program that calls up everything else.

Now, on the calculator, type index8() [Enter] to access the Calc 1 files, and index9() [Enter] to access the Calc 2&3 files.

Enjoy!
