<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 port and a mini-USB port . More details about the calculator's math and programming features were published when TI began distributing review models in February 2013, and even more when the calculator was released in 2013 . </P> <P> The TI - 84 Plus CE was publicly previewed by TI Education in January 2015, and released Spring 2015 . The calculator retains the 320x240 - pixel color screen, rechargeable battery, and key layout of the TI - 84 Plus C Silver Edition, while removing the 2.5 mm I / O ("DBUS") linkport and moving the USB port and charging LED to the right side of the handheld . 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 . It uses the eZ80 processor from Zilog, making all Z80 assembly programs from previous 84 Plus series calculators incompatible . 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 . The calculator comes programmed with seven different languages (English, French, German, Portuguese, Spanish, and Swedish). 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> <P> There are three different types of programs which can be downloaded or programmed into the calculators: TI - BASIC, Z80 assembly language, and Flash applications (also written in Z80 assembly). The TI84 + CE is different in that programs are written in TI - BASIC, eZ80 assembly language, or in the C programming language . In addition, there are programs available that are able to compile or interpret other programming languages . Also, there are several languages developed by community members for the calculators, notably ICE, which is for the TI84 + CE, and Axe, which is for the TI84+ and TI84 + SE . There are a wide range of applications that this produces, from science classes, to games, to calculus to note taking (when put together with a separately sold keyboard). The TI - 84 Plus Series is exactly like its predecessor in that it can be used on the SAT and ACT examinations as well as International Baccalaureate examinations . However, in some cases those administering the exam may reset the calculator's memory beforehand to prevent cheating through the use of built in programs or other data . </P>

When did the ti 84 plus ce come out
