<P> TI offers a special yellow version of the TI - 84 Plus, inscribed with the words "School Property", for schools to loan out to students . This special design was produced in effort to combat theft . Owners can buy other interchangeable colored face - plates and slide - cases online . A kickstand - style slide case and other accessories are also available . Although graphing calculators have been called inexpensive in education reform research, the TI - 84 Plus Silver Edition costs $139.00 as of 2013 on the TI online store . This calculator has been discontinued in favor of the TI - 84 Plus C Silver Edition . </P> <P> In 2011, TI launched for the French market a miniaturized version of the TI - 84 Plus: the TI - 84 Pocket.fr . In 2012, TI launched for the Asian market a miniaturized version of the TI - 84 Plus Silver Edition: the TI - 84 Plus Pocket SE . </P> <P> The TI - 84 Plus C Silver Edition was first publicly referenced in October 2012 in a tweet from TI . Even though this tweet had gone unnoticed, in November 2012, it was discovered through a leak from a pilot class that TI was developing a color - screen TI - 84 Plus, tentatively called the TI - 84 Plus C Silver Edition . It has a high - resolution 320x240 - pixel color screen, a modified version of the 2.55 MP operating system, a rechargeable battery and keystroke compatibility with existing math and programming tools . It has the standard 2.5 mm I / O linkport and a mini-USB port .

The calculator's OS 5. x is incompatible with the TI - 84 Plus C Silver Edition's hardware . The calculator has 154KB of user - accessible RAM and 3.0 MB of Archive memory .

The CE comes in multiple colors, Classic (black), Silver Linings, Radical Red, True Blue, Denim (navy blue), Lightning (light blue), Plum Pi (purple), Positively Pink (as of March 2015), Golden Ratio, and Bright White (as of June, 2016). Like the rest of the 84 Plus series, it is allowed on most standardized tests . In 2016, the TI - 84 Plus CE - T was released for the European educational market . The only significant difference from the CE model is the addition of an LED that blinks while the calculator is in Press - to - Test mode . </P>
