Why doesn the grayscale work?
A5.2: Most grayscale problems on the TI-89 with assembly programs are due to changes in the HW2 calculator. Different library files have been written because of this, though, and if you have a HW2 calculator you can send the files in the hw2 folder of the DoorsOS zip file instead of the corresponding files in the main directory. The screen might flicker a bit but at least the programs will be in grayscale. More information about fixing problems with HW2 calculators is available in Section 6.0.
