Notes:	The Texas Instruments The TI-89 Titanium is basically the same as the TI Voyage 200 but housed in a more standard looking vertical housing. It has a dot matrix display of 160x100 pixels. Much less than the 240x128 pixels of the TI Voyage 200. This sometimes makes the display difficult to read, especially with lower case text, as can be seen in this example. Personally I prefer the TI Voyage 200 to work with. There is an online simulator of this calculator here (link validated 2026-10-27). A lot of useful information can be found on this Wikipedia page (link validated 2026-10-27).
