application compatibility to SCO Unix (formerly UnixWare) and OpenServer. "The idea was to enable developers to write for both, Unix and Linux, with a common Application Programming Interface (API) and common Application Binary Interface (ABI). That way, developers didn't have to work so hard, and Unix users, the client base we inherited from SCO, could run Linux applications." Caldera also supported Alan Cox in his work on SMP. If Linux displaced Unix on the Intel x86 platform, then Sun Microsystems wouldn't have a low-end Unix path. This point becomes more interesting in light of SCO's litigation eight years later against IBM in 2003. That is, IBM was not the company involved in the SMP work, and moreover, the company most directly involved is the company that later became the SCO Group, essentially SCO suing IBM for work it itself did. In 1995, when XFree86 was still very hard to configure and unreliable on most chipsets, Caldera had shipped with MetroLink's Motif and XI Graphic's Accelerated-X. Known releases: Caldera Network Desktop 1.0 Preview I (1995-05) Caldera Network Desktop 1.0 Preview II (1995-09) with Linux kernel 1.2.13 Caldera Network Desktop 1.0 (scheduled for 1995-11, released 1996-02-05) Caldera Network Desktop Bundle (scheduled for 1995-12, released 1996-02-05) Caldera Network Desktop was produced and sold until March 1997. Caldera OpenLinux During 1996, Caldera continued to be a valuable player, for example, on 23 May 1996, at the Linux Kongress in Berlin, Germany, Caldera announced its plans to obtain POSIX and FIPS certifications and the X/Open brand for UNIX 95 and XPG4 BASE 95 for the Linux operating system kernel and "Open Linux". In contrast to CND OpenLinux was based on LST Power Linux, a Slackware-derived distribution that had been maintained by Linux Support Team since 1993 and the first to come with a Linux 2.0 kernel. In 1996 Linux Support Team grew into Stefan Probst's and Ralf Flaxa's company LST Software GmbH (with LST now standing for Linux System Technology) in Erlangen, Germany. The OpenLinux development led them to become Caldera's German development center Caldera Deutschland GmbH since May 1997. On 23 July 1996, Caldera purchased Novell DOS and the remaining Digital Research assets from Novell in order to bundle a DOS with their version of Linux, which led to creating the OpenDOS distribution to help port DOS applications. Caldera supported the Linux-port of StarOffice 3.1 with ca. 800.000 DM in order to offer the
