Re: I have a copy of xenix
This is correct.
Santa Cruz (the original SCO) sold some part of its business to Caldera, and then renamed itself Tarantella.
Caldera renamed itself as "The SCO Group" and became the evil SCOundrels we all know and hate.
The original Santa Cruz Operation was a fun place to work at (I had friends there), and while their Unix was a bit on the old and stodgy side (SVR3), it worked well.
