This colorful TI-84 Plus C Silver Edition was introduced for the Back-to-School 2013 campaign by Wal-Mart, the largest grocery retailer in the United States together with its blue sibling and the TI-30X IIS in matching colors of maroon, blue and gray.
In 2013 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 C Silver Edition manufactured in May 2013 by Kinpo Electronics, Inc.in China with a traditional TI-84 Plus Silver Edition reveals only few differences. The design sports still 3 chips:
• TI-REF84PLUSB/TA3: Z-80 microprocessor, RAM, USB-Port
and supporting logic
• Macronix MX29LV320: 4M Byte Flash-ROM
• Ilitek I9335: Single-chip 320*240 pixel display driver
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.
Recently members of the Graphing Calculator Programming community under the lead of Xavier Andréani made a very interesting discovery.
|• All TI-84 Plus / S.E. with the TA2 or TA3 ASIC have access
to 128k Byte RAM.
• All TI-84 Plus / S.E. with the TA1 ASIC have access to only 48k Byte RAM using
the same assembly commands.
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. The
new operating system 4.0 of the TI-84 Plus C Silver Edition is based on the
2.55MP, a minor bug fix of the 2.53MP from January 15, 2011.
