To
reduce theft of this new school-owned TI-34 MultiView
calculator, Texas Instruments
introduced in 2008 the EZ-Spot Teacher Packs with a bright, easy-to-spot,
"school bus yellow" back cover and slide case.
In addition, each unit's faceplate is inscribed with the
words, "SCHOOL PROPERTY."
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
manufactured by Kinpo
Electronics, Inc., a well-known company with OEM calculator production
facilities in China.
Early models of the TI-34 MultiView
calculator were manufactured by Nam
Tai Electronics, Inc. in
Shenzhen, China.
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.
