Coherent – a clone of the UNIX operating system for Intel 286/386/486 based systems.

In 1992 COHERENT 4.0 for the 386/486 was released, and the whole system looked pretty much like the UNIX System V.3 boxes. This is meant API wise, UNIX System V.3 has many more features than COHERENT, but it is possible to get most software written for UNIX working on COHERENT. Also the system is iBCS2 compatible, so it runs the same shrinkwrap applications like the other 386 UNIX systems from SCO, Interactive and so on. The old HDB uucp was replaced with Taylor uucp from Ian Lance Taylor, which you’ll still find on almost any modern UNIX systems nowadays.

In 1994 Mark Williams released COHERENT 4.2, with STREAMS, POSIX.1 and POSIX.2 compatibility and other features, that made the system pretty much look like UNIX System V.4. Again, meant API wise, UNIX System V.4 has many more features than COHERENT.

In January 2015, Robert “Bob” Swartz (founder and president of MWC) agreed to open posting of COHERENT command and system sources under this Open Source license.

The operating system was a proprietary product, but it became open source in 2015, released under a 3-clause BSD License.
Developer of the project is Mark Williams Company (MWC), the company was closed in 1995.
