This
colorful TI-84 Plus Silver Edition was
introduced for Back-to-School 2007 campaign by office product retailer Office
Depot together with a pink TI-30X
IIS.
In 2007 Texas Instruments sold on its website faceplates in 14
different colors: Black, brown, dark red, red, pink, purple, darl blue, blue,
light blue, green, gold, orange, bright orange, grey and white. Exept bright
orange were matching slide cases available, too.
Comparing
the TI-84 Plus Silver Edition manufactured in April 2007 with an early product
assembled in 2004 reveals only few differences. The design sports still 3 chips
on one printed circuit board (PCB):
 | TI-REF84PLUSB/TA3: Z-80 microprocessor, RAM, USB-Port and supporting logic |
| Spansion S29AL016D: 2M Byte Flash-ROM |
| Toshiba T6K04: Single-chip 64*128 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.
