The AMiTY SP was a mobile computer announced by Mitsubishi Electric in March 1996. Packaged in a compact A5-file-sized case, the AMiTY SP featured a 7.5-inch high-resolution DSTN LCD screen capable of displaying 65,536 colors. The operating system was either Microsoft Windows for Pen Computing 1.1 or Microsoft Pen Service for Windows 95. It came with 13 software programs preinstalled, including communication programs for networking, email, Internet, faxing, and infrared communications, and information management functions such as a scheduler, address book, and note keeper.
The AMiTY SP came with Mitsubishi Electric’s proprietary online handwriting recognition engine, which could recognize katakana, hiragana, alphanumeric characters, symbols, and handwritten kanji characters (2,965 JIS Level 1 characters and 728 JIS Level 2 characters (primarily characters for names)). The computer came with a variety of tools, such as menu selections, handwritten memo entry, handwritten character entry, and a screen keyboard. All functions were easily accessible with the pen.
The AMiTY SP could also be used as an excellent space-saving desktop computer by connecting it to its docking station.
