The Microwriter is a hand-held portable word-processor with a chording keyboard. First demonstrated in 1978, it was invented by UK-based, US-born film director Cy Endfield and his partner Chris Rainey and was marketed in the early 1980s by Microwriter Ltd, of Mitcham, Surrey, UK. By using a mnemonic alphabet, it was claimed to allow note-taking of up to 8,000 characters at an input rate averaging 1.5 times that of handwriting.〔(Microwriter ''Technology Week''20 March 1982 p39 )〕 == The Microwriter MW4 == Although there was an earlier unit with an LED display,〔(【引用サイトリンク】url=http://www.loper-os.org/pub/mw/mw_adbooklet.pdf )〕 the MW4 with an LCD was the most common unit. The 23 cm × 12 cm × 5 cm device comprises: * A six-button chording keyboard. * A single line LCD display. * An 8 bit CDP1802 microprocessor. * Complete Word processing software in ROM.〔(【引用サイトリンク】title=Microwriter )〕 * 16 kilobytes of RAM. * Rechargeable Nickel-cadmium batteries - sufficient to run the device for 30 hours.〔 * Various interfaces (see below). This device is capable of allowing the user to enter and edit several pages of text - and by connecting a printer to the RS-232 serial port connector, documents can be printed without the aid of a separate computer.〔 It was first sold in the UK in most mailorder shops in computing magazines such as YOUR COMPUTER from Spring/Summer 1983 and cost around £400-£500 (equivalent to around £1500 in 2014). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Microwriter」の詳細全文を読む スポンサード リンク
