The Osborne Vixen was a "luggable" portable computer announced by the Osborne Computer Corporation in November 1984, as a follow up to their Osborne 1 and Osborne Executive system.〔Peggy Watt, (''Osborne shows new computer'' ) ''Info World'' magazine, November 12, 1984, retrieved from Google Books December 16, 2009〕 The Vixen had a 4 MHz Zilog Z80 microprocessor, with 64 KB dynamic RAM. It had a 7-inch diagonal amber display that could show 24 lines by 80 columns of memory mapped video. It used two 400 KB disk drives, utilizing double-density double-sided 5.25" diskettes. As a luggable, it weighed about 18 pounds. Contemporary advertising pointed out that it could fit under the seat in an airplane, with dimensions of 12 by 16 by 6 inches (321 by 413 by 159 mm). When it was released, the Vixen had a retail price of $1298. Customers also had the option of purchasing a 10 megabyte hard disk for $1498. The Vixen used version 2.2 of the CP/M operating system. It was also bundled with a number of software packages: WordStar, the popular word processing package; SuperCalc, a spreadsheet; MBASIC, a programming language; Osboard, a graphics and drawing program; TurnKey, a system utility; MediaMaster, a data interchange program that allowed compatibility with over "200 other computers"; and Desolation, a game. The Vixen was also known as the Osborne 4. It was developed and released after the bankruptcy of the Osborne corporation. An earlier system also called "Vixen" was never released.〔John Dvorak, Adam Osborne, ''Hypergrowth: the rise and fall of Osborne Computer Corporation'' ,Idthekkethan Pub. Co., 1984 ISBN 0-918347-00-9, page 70〕 Due to technical problems with prototypes and the corporate bankruptcy, by the time the CP/M Vixen was introduced, it had already been made obsolete by MS-DOS IBM PC compatibles.〔Robert J. Thierauf, ''A problem-finding approach to effective corporate planning'', Greenwood Publishing Group, 1987 ISBN 0-89930-262-9, pages 15–16〕 A last ditch effort to design and market a fully IBM PC compatible produced three prototypes, but too late to save the company from bankruptcy. ==Software== 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「Osborne Vixen」の詳細全文を読む スポンサード リンク
