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 manufactured 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 1^st, 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.
