This colorful TI-84 Plus Silver Edition was introduced for the Back-to-School 2009 campaign by office product retailer Staples together with its pink sibbling.

In 2010 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.

Comparing this TI-84 Plus Silver Edition manufactured in September 2009 (Revision Code M) by Inventec (Pudong) Corporation with an early product assembled in 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
Macronix MX29LV160: 2M Byte Flash-ROM
Novatek NT7564H: Single-chip 64*120 pixel display driver

The picture on the right gives an enhanced view of the ASIC that clocks the Z-80 microprocessor with 15 MHz and incorporates the RAM, USB-Port and logic.

A component not easily detected on the printed circuit board (PCB) of the TI-84 Plus Silver Edition is the driver circuit of the LC-Display. It is just a bare chip mounted on a flexible piece of circuit board attached between the display and the main PCB. 


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.

This blue TI-84 Plus Silver Edition was avilable for the Back-to-School 2010 campaign by the retailers Staples and Office Depot. Don't miss the black sibbling of the calculator introduced in 2010, too.
