To reduce theft of this new school-owned TI-30XS MultiView calculator, Texas Instruments introduced in 2007 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-30XS 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 prominent SR-21 designation on the main PCB proves that this calculator was manufacturered by Kinpo Electronics, Inc., a famous company located in Taiwan and doing calculator production for well established companies like Texas Instruments, Hewlett Packard, Casio, Canon and Citizen.
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.
