Summary
Digital Research created DR DOS as an compatible alternative to MS/PC-DOS. It was purchased by Novell, and renamed Novell DOS, then purchased by Caldera and named OpenDOS. Caldera made it open source, and has transferred rights to its wholly owned subsidiary Lineo. It was then sold to DeviceLogics, where it appears to no longer be available as open source or as a free download. A new company DRDOS, Inc. now has the rights to DRDOS.
