Tarantella

Tarantella: the company formerly known as The Santa Cruz Operation, or SCO. SCO were a UNIX company who helped Microsoft port their version of UNIX, Xenix, to the 8086. SCO went on to be responsible for the product throughout the 1980s and 1990s, paying Microsoft royalties until at least 1997.

In 1996, SCO became the distributor and royalty collector for UNIX System V, at that time owned by Novell. Royalties were paid to Novell, with 5% being remitted back to SCO. SCO developed enhancements to UNIX and Unixware during this time, selling the latter along with Openserver (the new name for Xenix).

In the late 1990s, SCO worked with IBM on the doomed Project Monterey, an attempt to create a single operating system from two UNIX variants, IBM's AIX and Unixware, to run on Intel's new Itanium processors.

In 2000, SCO sold their UNIX division to Caldera, a Linux distributor, and changed their corporate identity to Tarantella, after their flagship product. Caldera's stated intention at the time was to merge the best of the UNIX and Unixware technology with Linux, and eventaully have one OS product rather than three. Caldera changed their name to The SCO Group, or SCO in May 2003, shortly after suing IBM and threatening many Linux users with lawsuits.
