context_page_description: The Leading Edge Model D is an IBM clone first released by Leading Edge Hardware in July 1985. It was initially priced at $1,495 configured with dual 5.25" floppy drives, 256 KB of RAM, and a monochrome monitor. It was manufactured by South Korean conglomerate Daewoo and distributed by Canton, Massachusetts-based Leading Edge. Engineer Stephen Kahng spent about four months designing the Model D at a cost of $200,000. Kahng later became CEO of Macintosh clone maker Power Computing.
  In August 1986, Leading Edge cut the price of the base model by $200, to $1,295, and increased the base memory of the machine to 512 KB.
  The Model D was an immediate success, selling 100,000 units in its first year of production. It sold well for several years, until a dispute with dealers forced Leading Edge into bankruptcy in 1989.
context_section_description: The unit comes with MS-DOS 2.11 or later, and a special edition of GW-BASIC to support the extended graphics mode.
  It also has a diagnostics disk.  This disk contained a diagnostics program, and `PARK.COM`, a utility used to park the hard drive heads when the computer was to be moved.  Most models also came with a word processing program developed by Leading Edge titled Leading Edge Word Processor, commonly referred to by its acronym 'LEWP'.
  The computer supports the Microsoft Windows operating system up to version 3.0, as it is the last version of Windows to support Real Mode.
