DR-DOS (DR DOS up to version 6.0) is an operating system of the DOS family for IBM PC personal computers. It was originally developed by Gary Kildall from Digital Research and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. After changed the ownership of the system, later versions was produced as Novell DOS 7.
In 1996 Novel sold the system to Caldera, who changed the name to Caldera OpenDOS 7.01 and released the source code of the kernel under an Open Source license. The name of the system has been changed back to DR-DOS and the model has been changet to closed source. Caldera Thinclients, a subsidiary of Caldera which later renamed itself to Lineo, continued the development of DR-DOS as an OS for embedded systems, before they abandoned its development in favour of Linux.
DR-DOS has been bought by Devicelogics company in November 2002.
In March 2004 the Devicelogics released DR-DOS 8.0 for the embedded systems market.
In July 2002, Udo Kuhnt used the source code of DR-DOS 7.01/OpenDOS as a base and started to write his own set of patches for it under a new the name of DR-DOS/OpenDOS Enhancement Project.
