I think that I know why. But it's a bit hard to explain in a
comprehensive way ...
This came from TI92. TI92 screen resolution is 240x128. For compatibility
TI89 screen is also 240x128 (I talk about memory). Then you must
write programs as if the screen have a resolution of 240x128 (and not
160x100). But only a part of the 240x128 is used. It's the upper left
part. Then there is 80 unused pixels a the end of each line (240 - 160)
and a there is 28 unused lines at the end of the screen (128 - 100).
I hope I well explain how LCD memory work ....
