Texas Instruments introduced in 2004 with the TI-82 STATS in France a Graphing calculator with some improvements compared to the original TI-82 Parcus. About two years later, in July 2006, with the TI-82 Stats.fr a Graphing calculator was nationalized for the French market.
In 2009, together with the introduction of the new
entry-level Graphing calculator TI-76.fr, the design
of the original TI-82 Stats.fr was changed to darker colors.
Dismantling this TI-82 Stats.fr manufactured in May 2009 reveals no surprises, the printed circuit board (PCB) is identical with its predecessor.
The picture on the right gives an enhanced view of the ASIC "TI-REF TI-738X" that clocks the Z-80 microprocessor with 6 MHz and incorporates the 32k Byte RAM and some supporting logic. The ASIC was probably manufactured by Toshiba and recalls us the TI-83 Plus Silver Edition with the "TI-REF 83PL2M/TA2" ASIC and the early TI-84 Plus with its "TI-REF 83PLUSB/TA2" ASIC.
The TI-82 Stats.fr is based - like most Graphing calculators introduced after the TI-73 - on Flash technology, we located in this TI-82 Stats.fr a Macronix 29LV400 device with 512k Bytes capacity for programs and data.
A component not easily detected on the printed circuit board (PCB) of the TI-82 Stats.fr is the driver circuit of the LC-Display. It is just a bare Toshiba T6K04 chip mounted on a flexible piece of circuit board attached between the display and the main PCB.
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.
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.
Texas Instruments France introduced in 2008 the TI-83
Plus.fr and in 2009 the TI-76.fr based on this
TI-82 Stats.fr. Don't miss the TI-82 Plus
introduced in 2014.
You can check the ROM version of your TI-82
Stats.fr using the following key sequence and reading the number on your screen:
