Texas Instruments announced in May 2007 with the TI-34 MultiView the successor of its long lasting TI-34 II introduced already in 1999 and slightly redesigned in 2004. 

Due to some design problems with the calculator it took until February 2008 before the TI-34 MultiView arrived together with the TI-Collège Plus finally in the store shelves. 

Instead of the then novel 2-line display the TI-34 MultiView 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. 

In addition to this so called "MathPrint" mode the calculator sports a TI-34 II compatible "Classic" mode.

Compared with the original TI-34 II, we notice some major improvements:

Classic (compatible with TI-34 II) and MathPrint 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
Toggle key fractions and decimals
Equation entries up to 80 digits

Dismantling the TI-34 MultiView reveals a pretty common construction with two printed circuit boards (PCB's). The main PCB hides the single-chip calculating circuit under a small protection blob of black epoxy and drives the graphing display with a heat sealed fine-pitch connector. The keyboard makes use of a much simpler second PCB and a heat sealed connector, too. The featured calculator was manufacturered by Nam Tai Electronics, Inc., a well-known company with OEM calculator production facilities in Shenzen, China.

We expect later in 2007 from Stokes Publishing Company, Inc. based in Sunnyvale, California a companion for the teacher with a projectable display. 

Don't miss the battery powered TI-30XB MultiView and its solar-cells operated sibbling TI-30XS MultiView sold since July 2007 and the close relative TI-Collège Plus.

Texas Instruments announced on March 1st, 2010 the TI-84 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.
