I would like to know if there exist a debugger/decompiler/emulator for the ti 89 titanium.

I have one, and would like to start writing software for it....but im missing tools such as a debugger, decomipler, or emulator...

I have the physical unit.

If you have the actual device, you don't need an emulator. Unless you are deconstructing existing TI-89 programs, you don't need a decompiler.

The processor in the TI-89 is a Motorola 68k. You should look for resources for that platform -- and serveral are available, as the 68k is not a new processor. You can code it in assembly or C. A quick Google search query returned this site that has the dedicated TI-89 information you're looking for: http://www.technoplaza.net/
