TI-83PlusFR_P1.jpg (406885 Byte)Texas Instruments France promoted already in 1988 with the Galaxy 10 a calculator with country specific particularities. Both the TI-40 Collège and TI-40 Collège II continued this approach in 1997 resp. 1999 and supported the "French fractions". Starting in 2005 Texas Instruments put another log on the fire and changed not only the computing algorithm but even keys, notations and menues to French language with the colorful TI-Collège.
Texas Instruments France introduced in 2006 with the TI-82 the first nationalized graphing calculator. In February 2008 hit the TI-Collège Plus the market and in June 2008 was this TI-83 introduced in the local market. Since 2009 we know the astonishing and a different color scheme of the TI-82, too. Don't miss the amazing TI-84 introduced in June 2011.

Xavier Andréani, a fellow TI calculator user in France, notified us already in October 2008:

Finally, I've got one student who has purchased a

What I had assumed is true: it's a TI83+ with translated keys, and it comes preloaded with the french translating application which can be disabled (I've tried) and probably removed (I haven't tried - it used to be on previous 83+ of course).

The rom version screen displays:
- BOOT CODE 1.01 (don't know exactly what this is... my TI-84+  displays 1.02 for example)
- BASE CODE 1.19

So they haven't updated the ROM (1.19 was already the last one for the TI-83+) for that french calculator, unlike the TI-82

The fine print: Production of the TI-83 Plus was moved from Inventec's Shanghai factory to Pudong (Date code S- vs P-) and the internal revision incremented (Date code K vs L). 

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 driver circuit of the LC-Display was traditionally manufactured by Toshiba for Texas Instruments' graphing calculators. This TI-83 Plus manufactured in 2007 shows with the Novatek NT7564H a one-by-one replacement. It is just a bare chip mounted on a flexible piece of circuit board attached between the display and the main PCB.

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.

In 2013 Texas Instruments introduced the next generation of the TI-83, now sporting the shell of the TI-84 Plus Silver Edition and in 2014 the TI-82 Plus continued the spirit of the original TI-83
