TI-82STATS_1.jpg (68998 Byte)Texas Instruments introduced in France mid of 2004 the stylish TI-82 STATS. At first glance it looks identical to the TI-82 Parcus available since 2001. The blue tone of the housing looks more valuable than the original dark grey housing from the TI-82 series but the overall design is still behind the TI-73 or TI-83 Plus graphing calculators. Main advantage of the housing is a neat access to the batteries with a sliding cover.

Since 2006 the TI-82 STATS is available in more European countries, we noticed it in Austria, Germany, Switzerland, and United Kingdom.

TI-82STATS_PCB.jpg (98414 Byte)Dismantling the TI-82 STATS reveals a printed circuit board (PCB) 100% identical with the TI-82 Parcus. The only real difference seems to be the enhanced Statistics Menu burned into the software of the calculator.

Comparing the TI-82 STATS with the TI-82 Parcus reveals some major improvements:

Additional statistics features to the TI-82: unlimited numbers of named lists with 
   up to 999 elements, automatic creation of the residual list in the Y=editor, use 
   any numbers as frequencies to calculate common statistical measures.
Multiple graph styles.
Interactive graphical analysis including numerical derivatives and integrals.
Up to 10 matrices.
Inferential statistics, probability distributions.
Complex numbers.
Interactive Time / Value / Money solver.

These specifications look very familiar to us – they are 100% identical with the TI-83 introduced in 1996 as an upgraded version of the TI-82. The last incarnation of the TI-83, the TI-83 Parcus introduced in 2000 and available only for about 2 years, sports even the same operating system known as ROM version 1.10001.

We prepared together with fellow collector Xavier Andréani a comprehensive comparison of entry level graphing calculators, to shed some light on the different specifications of the TI-82 and TI-83 / TI-83 Plus based products.

Please notice on the screen shot on the featured calculator that the menus are in English language. Texas Instruments introduced in 2005 with the TI-Collège the first calculator with keys, notations and even the menus in French to simplify the use by younger students. Almost one year later with the TI-82 a Graphing calculator was nationalized.

A serial port of the calculators allows the connection to the Calculator-Based Laboratory system CBL, its successor CBL 2, the Calculator-Based Ranger CBR and its successor CBR 2.



You can check the ROM version of your TI-82 STATS using the following key sequence and reading the number on your screen:
