Texas Instruments introduced in February 2008 with the TI-Collège Plus the successor of its TI-Collège 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..

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
	Function table
	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.

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-34 MultiView.
