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.
