This pink colored TI-30XS MultiView was manufactured by Kinpo Electronics, Inc. for the office product retailer Office Depot. It was released for the Back-to-School 2011 campaign together with a pink TI-30X IIS and the TI-84 Plus Silver Edition in the colors of pink and black. Staples added this TI-30XS MultiView for the Back-to-School 2012 campaign to its selection.  

Instead of the 2-line display of the TI-30X IIS feature both the TI-30XS MultiView and its battery only powered sibling TI-30XB MultiView 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-30X IIS compatible "Classic" mode.

Compared with the original TI-30X IIS, in the US the quasi-standard for pupils, we notice more bang ($15.99 versus $14.99) for the bucks: 

Classic (compatible with TI-30X IIS) 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-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. 

Please compare the TI-30XS MultiView with its competitors Canon F-718SG, Casio fx-300ES, Citizen SR-270X aka Ativa AT-30SX, Hewlett-Packard SmartCalc 300s, and Sharp EL-W535.
