This colorful TI-84 Plus Silver Edition "Raspberry Sorbet" was introduced for the Back-to-School 2008 campaign by office product retailer Office Depot together with its orange sibbling "Blaze". Don't miss the pink predecessor introduced in 2007. For the Back-to-School 2009 campaign Office Depot switched to the pink colored TI-84 Plus S.E. introduced by its competitor Office Max.

TI-84PlusSE_OD_PK2008_KBD.jpg (606672 Byte)In 2008 Texas Instruments sold on its website faceplates in 15 different colors: Black, brown, dark red, red, pink, purple, dark blue, blue, light blue, green, gold, orange, bright orange, grey and white. Except bright orange were matching slide cases available, too. One special “Data Collection” snap-on faceplate highlights the keys and functions of the Vernier EasyData™ application.

TI-84PlusSE_OD_PK2008_PCB.jpg (367196 Byte)Comparing this TI-84 Plus Silver Edition manufactured in May 2008 (Revision Code M) by Inventec (Pudong) Corporation with earlier ones manufactured in March 2008 (Revision Code L) and April 2007 (Revision Code G) reveals only few differences. The design sports still 3 chips on one printed circuit board (PCB):

TI-REF84PLCR/TA1: Z-80 microprocessor, RAM, USB-Port 
    and supporting logic
Spansion S29AL016D: 2M Byte Flash-ROM
Novatek NT7564H: Single-chip 64*120 pixel display driver

TI-84PlusSE_OD_PK2008_LCD.jpg (58295 Byte)The driver circuit of the LC-Display was traditionally manufactured by Toshiba for Texas Instruments' graphing calculators. This TI-84 Plus Silver Edition manufactured in 2008 shows with the Novatek NT7564H a one-by-one replacement. It is just a bare chip mounted on a flexible piece of circuit board attached between the display and the main PCB.

There are minor differences between the components located in the different production batches:

The TI-84 Plus Silver Edition supports the ViewScreen panel and the TI-Presenter with an Presentation Link Adapter. A serial port of the calculators allows the connection to the Calculator-Based Laboratory system CBL, its successor CBL 2 and the Calculator-Based Ranger CBR. The added USB interface of the TI-84 Plus family calculators connects directly with the Calculator-Based Ranger CBR 2 introduced in 2004. With a new cradle even the optional full-sized QWERTY Keyboard introduced in 2002 matches with the TI-84 Plus series.

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.
