Texas Instruments announced in May 2007 with the TI-30XS MultiView the improved version of its long lasting TI-30X IIS introduced already in 1999 and slightly redesigned in 2004. In some European countries, e.g. Germany, Switzerland, and United Kingdom, with the TI-30XB MultiView a battery only powered replacement of the original TI-30X IIB hit in July 2007 the store shelves. This wonderful green/blue/white housing was reserved for the French market.

Instead of the previous 2-line display the TI-30XB 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-30X IIB compatible "Classic" mode.

Compared with the original TI-30X IIB, the quasi-standard for pupils, we notice more bang (typical street price EUR 17.95 in July 1997) for less bucks:

• Classic (compatible with TI-30X IIB) 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-30XB 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-21B 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.

Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the wonderful TI-30XS MultiView Overhead Calculator.
