Texas Instruments will be releasing a color-screen TI-84 Plus calculator next year, according to Cemetech member 0rac343. In a post published this morning, he mentions that his class was chosen by TI as a pilot to test the reception of these new devices. It has the same key layout and case as the standard TI-84 Plus and TI-84 Plus Silver Edition calculators, but appears to have a much higher-resolution, 320x240-pixel screen. He says that the interface feels familiar from using older TI-84 Plus calculators, but that it has slight tweaks and changes. We will be pursuing this story closely and bringing you more details as we get them.
Edit, November 11, 2012: Welcome to all our Slashdot and Engadget visitors. We have gotten official confirmation from TI in the form of a tweet from TI and a form on TI's site where you can request notification when more information is available. Feel free to register for a Cemetech account and discuss this development with us. In particular, we are looking to discover if this calculator will have a z80, ez80, or ARM CPU, and if it will replace the controvertial TI-Nspire calculators. We are collecting all of the updated details as soon as we get them on our TI-84 Plus C Silver Edition page. Come discuss the possibilities with us!
Confirmed Features (thanks to Adriweb at TI-Planet): :: 320x240-pixel, 16-bit color LCD
:: TI-Nspire-style rechargeable battery
:: z80 CPU (speed unknown)
:: Keystroke-compatible OS (that is, same functions and interface as TI-84+/SE calculators)
