Re: Re: A89: Re: Fw: TI-89 ROM 1.05 vs 2.00 version inquiries




It is possible to have the same greyscale routine work on both HW versions,
but first we need to get it to work on the HW2.  SMN has been working on
this (I hear) but hasn't gotten it to work correctly yet.

The reason why greyscale doesn't work on the HW2 is because
graphlib/grayXlib use a randomly found hunk of memory the TI-OS gives.  HW2
is more picky (has to do w/ the speed of the homescreen while refreshing)
and the LCD can only be mapped to a few designated memory areas.
