DrDOS TimeLine

Dr-DOS was originally created by Intergalatic Digital Research, Inc, in Pacific Grove, California.

Digital Research, Inc, was the successor in interest to Intergalatic Digital Research, Inc.

Novell bought (1991) Digital Research, Inc. with the idea of shipping a SOHO OS that included networking, and an office suite.(WordPerfect, Quattro Pro, Paradox, DrDos, Novell Lite, and a couple of other things.)

The SOHO OS didn't work out for Novell. NovellOffice was sold to in Corel (1996). (Corel Linux was sold to Xandros in 2001.)

Caldera started off as an internal group to develop a Linux distro for Novell. Caldera Systems was spun off by Novell, in 1996, taking most of the operating systems with it. Caldera Systems, in turn, spun off Caldera Thin Clients, which, in turn, (1998) became Lineo Solutions, INC. Dr-Dos was then opensourced. DrDos was then spun off into DeviceLogics, and became closed source. Metrowerks bought out DeviceLogics, who then spun it out (2002) as part of DrDOS, Inc. The other spinoff was Caldera Internatinal, which developed Caldera Linux. (Caldera Linux in 2001 used a Unix kernel, not a Linux kernel.)

Tarantella Enterprise was a product from Santa Cruz Operations that resulted from their purchase (1994),and integration of half a dozen minor companies.

Santa Cruz Operations sold their Unix business to Caldera Systems Inc, in 2001. Santa Cruz Operations then renamed themselves Tarantella, Inc. In 2005, Sun purchased Tarantella, Inc.

in 1995 Novell sold the right to distribute UnixWare to Santa Cruz Operations. Santa Cruz Operations, in turn, sold those rights to Caldera Systems, Inc, in 2001.

In 2002, Caldera Systems, Inc renamed itself SCOGroup.
