AIX v2 included full TCP/IP networking support, as well as SNA, and two networking file systems: NFS, licensed from Sun Microsystems, and IBM Distributed Services (DS). Some RT PCs were also shipped with the Academic Operating System (AOS), an IBM port of 4.3BSD Unix to the RT PC. Most industry watchers considered the RT as "not enough power, too high a price, and too late."[citation needed] Many thought that the RT was part of IBM's Personal Computer line of computers.
