Thank you for your questions. I asked our product development team and have some information on how the graphics will work on the TI-89. The fonts and other graphics on the TI-89 will be scaled down so that any image information from the TI-92 will fit. The smaller fonts will be carried through for dialog boxes, the graphing screen etc. The following is some information about the pixel sizes of the various parts of the TI-89 LCD: Screen Part # Pixels Toolbar 15 Edit Line 11 Status Line 6 History Screen 68 ---------------------------------------------------- Total Vertical Pixels 100 Total Horizontal Pixels 160 # of Characters is variable because we use several different fonts to display information, but average is 160/6 = ~26 I hope that this is helpful to you. If you have any further questions or comments please feel free to contact us at your convenience.

This technology allows us to increase the number of pixels per inch and therefore decrease the size of the LCD. This means that while the screen itself is about the size of that on a TI-86, it has a resolution that is much closer to that of the much larger TI-92 screen. For reference, the TI-86 has a screen that 128 by 64 pixels, the TI-92 has a screen that is 240 by 128 pixels and the TI-89 will have a screen that is 160 by 100 pixels. >> You state the dimensions of the screen; how will all the toolbars and stuff fit on the screen? Also, do you know what the working dimensions (how many pixels up and down) a program can display a picture? (The screen size minus space for toolbars) Do you know how many characters wide can fit across the screen? You say that the ROM will be the same as that of the 92 plus, is there any way l can suggest and idea?
