  • INTRODUCTION

    The TI-89 Titanium includes all the built in functionality and power of the original TI-89. It has an increased amount of Flash ROM which is now equal to that of the Voyage 200 except the TI-89 Titanium is in a traditional handheld design. Along with the Voyage 200, it is TI's most sophisticated calculator, with such features as 3D graphing, upgradable flash ROM, built-in assembly language programming, and a generous amount of user-available memory. It now includes a mini USB port in addition to the standard I/O port.

    ASSEMBLY PROGRAMMING

    Assembly language programming capability is built into the TI-89 Titanium. Assembly programs written for the TI-92, TI-92 Plus and Voyage 200 must be modified to support the TI-89.
