AT&T sold UNIX V.4 to Novell who brought out UnixWare and then sold it to SCO. NCR developed AT&T UNIX V.3 for their TOWER Systems and then switched to their version of AT&T UNIX V.4 for their Intel boxes. NCR MP-RAS 2.xx & 3.xx share much of the same code with UnixWare. -- Semper Fi Jack L http://members.aol.com/jitb/stand.htm "Luke, you're going to find that many of the truths we cling to depend greatly on our own point of view." - Obi-Wan Kenobi, ROTJ
