Casio ClassPad 300とは 意味・読み方・使い方

The Casio ClassPad 300 is a stylus based calculator. HP worked on a pen based calculator called the HP-Xpander, as did Texas Instruments under their PET Project (see TI PLT SHH1), yet both projects were cancelled before they were released to the market. The ClassPad comes with a collection of applications that support self-study, like 3D Graph, Geometry, eActivity, Spreadsheet, etc. A large 160x240 pixel LCD touch screen enables stylus-based operation. There is a strong resemblance between the ClassPad and the older Pocket Viewer line.
