In 1969, the UNIX system was created. Dennis Ritchie and Ken Thompson used a minicomputer PDP-7 to invent the first model with the intent to craft a time-sharing computer system. Link text -
The "pipe" was a way for information to be shared between multiple programs. This also helped UNIX to switch from assembler to C.Link text -
This marks when the system was rewritten in C. This allowed it to become portable which was a big deal due to the fact that it made OS history.Link Text -
UNIX is shared with the public via the monthly journal of the Association for Computing Machinery. The outcome became it producing the first big demand for UNIX.Link text -
The sixth version of UNIX was the most influential version. This version was the first to be widely distributed outside Bell Labs.Link text -
Bill Joy has copies sent out of the first Berkley Software Distribution (1BSD), which is Bell Labs' UNIX v6 with add-ons. This become a rival UNIX branch to AT&Ts UNIX.Link Text -
This was the last version of UNIX to come from Bell Labs. It was a multi-tasking and multi-user. This version included games such as chess, checkers, backgammon, and hangman.Link Text -
Dennis Rithie and Ken Thompson were the creators of UNIX and ended up winning the Turning awadrom from ACM honoring their development of generic operating systemps theory.Link Text -
System V Interface Definition. This was an important effort in early regulation of UNIX during a time when UNIX variants were rapidly multiplying and portability was problematic. Around this time AT&T required compliance with SVID if vendor's were going to brand their products.Link Text -
Sun Microsystems, AT&T, and Bell Labs came together to produce a new system, that would be used to bring together two major UNIX branches. MINIX was then created by Andrew Tanenbaum. MINIX was a clone of UNIX which was used in science classrooms.Link Text -
Since AT&T and Sun developed a partnership, the rivals of UNIX formed the Open Source foundation to create new open standards. AT&T went on to create their own standard group called UNIX International.Link text -
The Sun microsystems announces Solaris with the public, which is another OS. This was inspired by the SVR4 as well as Linux Torvalds writing of Linux, which was an OS inspired MINIX.Link text -
AT&T sells its subsidiary UNIX System labs and UNIX rights to Novell. Later in the year Novell transfers the UNIX trademark to the X/open group.Link text -
President Clinton awards the inventors Dennis Ritchie and Kenneth Thompson of the UNIX operating sytem and the C programming langauge the National Medal of Technology.Link text -
Stock LINUX outperforms most proprietary UNIX systems.Link Text
