This colorful TI-84 Plus Silver Edition was introduced for Back-to-School 2008 campaign by retailer Target together with a maroon colored TI-30X IIS. Don't miss the blue predecessor introduced in 2007.

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.

Comparing this TI-84 Plus Silver Edition manufactured in March 2008 (Revision Code L) 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
Spansion S29AL016D: 2M Byte Flash-ROM
Toshiba T6K04: Single-chip 64*128 pixel display driver
