Texas Instruments TITANIUM TI-89 User Manual page 739

Most functions of the TI-89 Titanium are compatible with the TI-89, Voyage™ 200, and
TI-92 Plus. The TI-89 Titanium and the TI-89 are similar, except that the TI-89 Titanium
has more memory (more room for Apps and user archive) and the TI-89 Titanium has a
USB port. The Voyage™ 200 is the same as the TI-92 Plus except it has more memory,
and thus more room for applications (Apps).
All data is compatible among the TI-89 Titanium, TI-89, Voyage™ 200, and TI-92 Plus,
but some programs written for one may not run or may not run the same on the other
because of differences in the device's screen sizes and keyboards and the USB port on
the TI-89 Titanium.
Other incompatibilites can occur because of different version the operating system. To
download the latest version of the operating system, visit the Texas Instruments Web
site at education.ti.com/downloadticonnect.
