Featured Scientific Calculator! 
Texas Instruments VOY200/PWB Graphing Calculator

From Texas Instruments

The Voyage 200 handheld has a huge 2.7 Mb of Flash ROM, lots of pre-loaded Handheld Software Applications (Apps), and a real-time clock. Not to mention the fact that it comes with the TI Connectivity USB cable for Windows and Macintosh computers. It still contains all of the inherent functionality of the TI-92 Plus, including 3-D rotations and contour plots, symbolic manipulation, systems of equations, syntax listings, and much, much more. And the QWERTY keyboard takes the drudgery out of programming and note-taking. Mathematical expressions appear on the display the same way as they are written on the board.
