Features: Texas Instruments TI-73
The TI-73 is a great compromise for those in the market for a full-featured scientific
calculator who don't want to spend a lot of money. The only real problem is that
the superior TI-82 is now available for about the same price, but if you have
your mind set on this model, it certainly won't disappoint.
The highlight of the TI-73 is its large display, which shows the history of
your calculations, depicts graphs and charts, and has a high enough resolution
to simultaneously display several rows of stacked fractions. The stacked-fraction
feature is a boon for struggling middle school students, as the results of
calculations involving fractions are displayed as fractions, not decimals.
The TI-73 is fully programmable and comes with a fairly large library of built-in
formulas, making things like time and distance conversions a snap.
The product comes with two features that few other calculators boast--firmware
with flash memory and link capabilities. The use of flash memory means Texas
Instruments can upgrade and enhance the features of the calculator and make
them available to TI-73 users without requiring a hardware upgrade. Instead,
you simply download the new firmware or software applications, connect the
calculator to your computer, and copy the new stuff over the old stuff. The
package comes with a cable for linking two calculators, but unfortunately,
the cable for connecting the TI-73 to your computer is sold separately.
Texas Instruments didn't skimp on the documentation and bundles a 350+ indexed
manual with the calculator. This tome is chock-full of illustrated examples
that demystify the device's more advanced features like statistical analysis,
lists, tables, and function graphing. We were graphing within 10 minutes of
unpacking the TI-73, and cobbling together simple programs within an hour.
The TI-73 is marketed as a calculator for middle school students, but it has
enough power and features to satisfy all but the most advanced high school
and college students. --T. Byrl Baker
