Unix started as two main families:
AT&T System V (System V Release 3, Solaris 2.x, AIX, HP-UX)
and
Berkeley's BSD (Ultrix, SunOS 3.x and 4.x, Solaris 2.x, SVR4)
These two merged into System V Release 4 (SVR4 or V.4).
The first two versions of Unix to merge was Xenix and System V.
In August 1988 it was released as Unix System V/386, release 3.12.
In 1988 AT&T and Sun versions merged into SVR4.
In 1988 Apollo, DEC, HP, IBM, and 3 European computer manufacturers
formed the Open Software Foundation (OSF) and formed OSF/1.
In 1995 Digital's OSF/1 version 3 was renamed Digital Unix 3.2.
The Unix system standards are POSIX 1003.1, 1003,2, 1003.1B,
XPG3 Base, XPG4 Base, SVID 3, Unix95 (SPEC 1170).
Networking include: TCP/IP, SPX/IPX, LAN manager, Ethernet,
Fast Ethernet, 100VG anyLAN, ATM, software router, 56KB, AppleTalk.
Distributed computing include: ONC-NFS, ONC-RPC, NFS-Diskless,
DCE, AFS, CORBA, and OpenStep.
User interfaces include X11 R5 or R6, Motif, and CDE.
XPG = X/Open Portability Guide
SVID = System V Interface Definition
SMP = symmetric multiprocessing
JVS = Journaling File System
ORB = object request broker
CORBA = Common Object Request Broker
