Yes I don't think it uses 68K they said on TI's official site that it will have 4X the power of the TI-89 Titanium and loads more memory with built-in greyscale and mouse routines with a better GUI then past calcs that uses a mouse. And also the resolution is better I think to and that is how they fit 4 windows onscreen for analyzing one problem in graph form wriiten and derived and stuff.
