S.L. Hollis' TI-89/92 math site
http://www.math.armstrong.edu/ti92/
Lots of very good math programs. Single and multi-variable calculus, linear algebra, differential
equations, probability, Gaussian quadrature and special functions. Very, Very Good Site!
Frank Westlake's site
http://frank.westlake.org/ti/
Several calculus functions, including directional derivative, gradient, partial and total derivatives,
multivariable limits, Taylor approximations for multi-variable functions. Notes on using Var-Link to
provide fast program and function documentation. Internet sockets to send and receive email with
your calculator. Number base conversions. Roman numeral conversions. Image editor. Remote
control with scripts. Lots of utilities for converting text files, including BMP, RTF, PIC, TEXT and
STR formats. You must disable Javascript in your web browser to use Frank's site.
Jack Hanna's Iview site
http://users.bergen.org/~tejohhan/iview.html
Get Jack Hanna's Iview program here. The program runs on a PC and converts graphics files to
PIC variables which can be viewed and manipulated on the calculator.
Rusty Wagner's site

Go here for the Virtual TI emulator (VTI). This is PC software that emulates the calculator. You'll
need to do a ROM dump from your calculator to run it. 'ROM dump' means uploading the
calculator ROM image to the PC with a GraphLink cable. ROM images are not legally available by
any other means.
The advantage to using the emulator is that you can test programs before downloading them to
your calculator. This can save battery life.

A very complete comparision between the TI-89 and the HP49G, with little or no bias. Some math
programs. Good assembly programming tutorials.

Advanced math functions for the 89/92+. Although this was written for the original TI92, and many
of these functions are now built into the 89/92+, there is still lots of good stuff here. In particular,
the code style is clever and efficient - you can learn a lot about programming by examining these
programs.
TI redesigned the web site in March 2001. The little remaining description of this function
packages is at http://education.ti.com/product/tech/92/faqs/faq20595.html
TI calculator program archives

Programs written by users and submitted to TI. Includes the inferential statistics package for the
89/92+.
