Instruments introduced in February 2008 with the TICollège Plus the successor of
its TICollège introduced already in 2005 as the first calculator with keys (e.g.
ANNUL), notations and even the menus in French to simplify the use by younger
students.
Due to some design problems with the
calculator it took until February 2008 before the TICollège Plus
arrived together with the TI34
MultiView finally in the store shelves. Don't miss one of the preseries TICollège Plus.
Instead of the then novel 2line display
the TICollège Plus features a dot
matrix display with 31 * 96 addressable pixels allowing the calculator to
display equations as they would be printed in a text book.
The TICollège Plus
is the first calculator in the new MultiView series sporting for the "mode
menue" a total of 5 lines by 19 characters on the small graphing screen.
Both the TI30XS MultiView
and the TI34 MultiView used just 4 lines.
In addition to this
so called "AFFNATUREL / MathPrint" mode the calculator sports a TICollège compatible "AFFLIGNE
/ Classic" mode.
Compared with the original TICollège, we notice some major improvements:
•
AFFLIGNE (compatible with TICollège) and AFFNATUREL Mode • EOS with 8 pending operations and 23 levels of parentheses • 7 memory variables x, y, z, t, a, b, c • Data editor and list formulas: 3 lists, each up to 42 items • Function table • Toggle key fractions and decimals • Equation entries up to 80 digits 
Dismantling the TICollège Plus reveals a pretty common construction with two printed circuit boards (PCB's). The main PCB hides the singlechip calculating circuit under a small protection blob of black epoxy and drives the graphing display with a heat sealed finepitch connector. The keyboard makes use of a much simpler second PCB and a heat sealed connector, too. The featured calculator was manufactured by Nam Tai Electronics, Inc., a wellknown company with OEM calculator production facilities in Shenzen, China.
Manufacturing of the TICollège Plus was shifted in 2011 from one contract manufacturer in China to another company and the design was slightly revised.
Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the wonderful TICollège Plus Overhead Calculator.
Don't miss the battery powered TI30XB MultiView and its solarcells operated sibbling TI30XS MultiView sold since July 2007 and the close relative TI34 MultiView.
Texas Instruments announced on March 1^{st}, 2010 the TI84 Plus Operating System version 2.53MP with MathPrint™ mode for free download. The OS 2.53MP enables users to input and view math symbols and formulas, including stacked fractions, in their handhelds exactly as the equations appear in textbooks.
The TICollège Plus was replaced
in 2013 with the TICollège
Plus Solaire.
