This
colorful TI-84 Plus Silver Edition was
introduced for the 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 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.
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 REF 84PLUSB/TA3: Z80 microprocessor, RAM, USB-Port
and supporting logic
• Spansion
S29AL016D: 2M Bytea Flash ROM
• Toshiba
T6K04: Single-chip
64*120 pixel display driver
The
picture on the right gives an enhanced view of the ASIC that clocks the Z80
microprocessor with 15 MHz and incorporates the RAM, USB-Port and logic. Learn more about the
Hardware Architecture of TI’s Graphing Calculators.
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.
Don't miss the TI-84 Plus Silver Edition "Blaze" and "Raspberry Sorbet" limited edition models introduced for the Back-to-School 2008 campaign.
