-Mach has quite a history. Everything actually started at the University of Rochester in 1975. It was invented to demonstrate how operating systems could be built using a modular design where processes processes communicated using message passing, even across networks. The system was called the Rochester Intelligent Gateway and ran on a 16 bit mini computer called Eclipse from Data General.

It was invented to demonstrate how operating systems could be built using a modular design where processes communicated using message passing, even across networks.

 One of the engineers behind the project was Richard Rashid. In 1979 he moved his socks to Carnegie Mellon University to continue his research on message passing operating systems. The result emerged in 1981 and was called Accent.
 
-Accent kept running at CMU until 1984 but was by then being run over by UNIX. Rashid then decided to use an early embrace strategy and started designing the third generation OS project called Mach. By making Mach compatible with UNIX Mach was supposed to gain a lot of available UNIX software.

-Mach was a vast improvement over Accent. It incorporated parts commonly used today, such as: threads, better IPC, MP support and an advanced VM system.

-At the time of Mach's conception DARPA was seeking a multiprocessor (MP) capable OS and found Mach. With money from the Dept. of Defense 4.2BSD support was added to bloat the kernelm but most of all to add complete UNIX compatibility.

 Now enters the UNIX war.
 
-UNIX was owned by AT&amp;T which controlled the market almost completely. Industry giants such as IBM, DEC and H got together and formed the Open Software Foundation, OSF. In an effort to conquer market share OSF took the Mach 2.5 release and made it the OSF/1 system. By that time Mach contained a lot of BSD and AT&amp;T code but the OSF hoped that it would be able to take control of the rudder with OSF/1. What happens after that is a story better told by someone else ...

 In 1989 CMU decided to revamp Mach. They removed the bloat and put the UNIX emulation in user space making the Mach 3.0 release -- the pure Mach release.
 
 Later on support for Mach 3.0 at CMU vaned and the project was taken over by the University of Utah. The FLUX group started the Mach4 project. An ambitious project which included complete rewrite of the x86 support code and integration of Linux 2.0 drivers. That's right, Linux awoke around 1991 so this makes it apx. 1994.
 
-GNUMach is based on Mach4 from University of Utah, which in turn is based on Mach3 from Carnegie-Mellon University. The last release of Mach4 was the [UK22 release](http://www.cs.utah.edu/flux/mach4-i386/html/mach4-UK22.html).

 The OSKit was what evolved when the Mach4 project at University of Utah was dropped. The people involved wanted to reuse the work they had put into Mach in the form of hardware support and drivers.
