Re: A89: Re: Re: Re: Re: Grayscale troubles




Interesting...
Maybe there's a bit somewhere in those ???s that causes the screen
microcontroller to re-load the screen data from RAM, making normal grayscale
possible again on HW2 (just set that bit after changing the LCD address).
Or maybe that's just wishful thinking.  Why doesn't TI release that SDK so
we can all stop poking and prodding our TI-89s to find stuff out?
    Great work on that info file, Johan!
