Texas Instruments TI-89 Tip List page 413

Will there be a TI-89 Plus?
The TI-89 already comes with the Flash memory. It is different from the TI-83 and TI-92, which were
introduced before the Flash memory became available on the calculator. Therefore there is no need to
introduce a Plus version of the TI-89 with the Flash memory update. TI has four graphing calculator
models with Flash capability: TI-73, TI-83 Plus, TI-89, and TI-92 Plus.
Is the TI-89 approved for College Board tests?
The TI-89 has been approved for some College Board tests, including AP Calculus and SAT.
What is the size of the TI-89?
The TI-89 will be the same size as the TI-83/86: 1.0 x 3.5 x 7.3 (in.).
Is the TI-89 available through the Workshop Loan Program?
Yes, teachers can borrow individual TI-89s for short term loans through TI's Workshop Loan Program.
Loans are based on availability.
Is the TI-89 compatible with the TI-92 and TI-92 Plus?
Yes, the programming functions and data on the TI-89 will transfer directly to and from a TI-92 Plus
using the included unit-to-unit link cable. Data and programs containing original TI-92 functions will
transfer directly to and from a TI-89.
Which ViewScreen LCD does the TI-89 use?
The TI-89 ViewScreen calculators use the same ViewScreen panels as the TI-92.
Does the TI-89 work with the TI-GRAPH LINK?
Yes. The TI-89 will works with the TI-GRAPH LINK cables.
What Data Collection tools is the TI-89 compatible with?
The TI-89 is compatible with CBL, CBL2, and the CBR.
How much memory does the TI-89 have?
The TI-89 provides two types of memory: RAM and user data archive memory. The user available
RAM is about 188K and can be used for computations and storing programs and data. The user data
archive has 384K of available space for storing additional programs and data.
What do Flash and electronically upgradable mean?
Flash is a technology that allows the calculators software to be upgraded electronically. Using the
TI-GRAPH LINK cable and the link I/O port, the software can be updated with the latest maintenance
updates or new software versions.
What is Advanced Mathematics Software?
Advanced Mathematics Software is the name of the software features available on the TI-89. The
software is named to identify which version of software is running once electronic updates are
available. This is the same Advanced Math Software of the TI-92 Plus, without the Geometry
application.
The key features of Advanced Mathematics Software are the Computer Algebra System, differential
equations, linear algebra, unit conversions, systems of equations, and 3D graphing with contour plots
and rotation.
What is the TI-89?
The TI-89 is a vertical graphing calculator that includes a symbolic Computer Algebra System (CAS),
Advanced Mathematics Software, and Flash technology that enables electronic upgradability.
