SunOS – a UNIX based OS derived from BSD, created by Sun Microsystems. Initially released in 1982, it was the standard OS on Sun Machines at that time. Platforms supported by this OS were the Motorola 68000, the Sun 386i, and the SPARC.

Sun-1’s were the very first models ever produced by Sun. The earliest ran Unisoft V7 UNIX; SunOS 1.x was introduced later. According to some sources, fewer than 200 Sun-1’s were ever produced; they are certainly rare. The switch from Motorola 68000’s to 68010’s occurred during the Sun-1’s reign. Some models are reported to have 3Mbit Ethernet taps as well as 10Mbit.
68000-based Sun-1’s are not supported by SunOS. The last version of SunOS to support Sun-1’s may be the same as the last version to support Sun-2’s, since the 100U CPU boards are the same part.

Sun-2’s were introduced in the early 1980’s and were Sun’s first major commercial success. While not as popular or as common as the later Sun-3’s, they did well and there are still quite a few in circulation in the home/collector-used market.
All Sun-2’s are based on the Motorola 68010 and run SunOS. The last version of SunOS to support Sun-2’s was 4.0.3. Early Sun-2’s were Multibus; later models were VME, which Sun continued to use through the Sun-3 era and well into the Sun-4 line.

Sun switched to using the Motorola 68020 with the introduction of the Sun-3’s. A few later models had 68030’s, but by that time Sun was already moving toward SPARC processors. All models either have a 68881 or 68882 FPU installed stock or at least have a socket for one. All models which are not in pizza box chassis are VMEbus. Two out of three pizza box models have a “P4” connector which can take a framebuffer; the exception is the 3/50.
Support for Sun-3’s was introduced in SunOS 3.0. The last version of SunOS to support Sun-3’s was 4.1.1U1.
During the Sun-3 era, Sun introduced the handy practice of putting the model number on the Sun badge on the front of the chassis.
There are two different kernel architectures in the Sun-3 model line. All 68020-based models are “sun3” architecture; 68030-based models (the 3/80 and 3/4xx) are “sun3x” architecture.

The Sun 386i models, based on the Intel 80386 processor, were introduced when 80386-based IBM PC/AT clones were starting to become widespread. Intel had finally produced a chip sufficiently capable (32-bit, among other things) to allow porting SunOS, and using an Intel processor and an ISA bus offered the ability to run MS-DOS applications without speed-draining emulation. Unfortunately, they were a dismal failure.
Support for Sun-386i’s was introduced in SunOS 4.0. The 386i SunOS releases came from Sun’s East Coast division, so 386i SunOS was not identical to the standard version with the same number. The last released version of SunOS to support Sun-386i’s was 4.0.2; there are a few copies of 4.0.3Beta (with OpenLook 2.0) floating around.

Support for Sun-4’s was introduced in SunOS 4.0, although there was a special variant of SunOS 3.2 for Sun-4’s which was shipped with some very early units. Since this product line is still current, it is still in general supported by SunOS, which has mutated to become part of Solaris. Support for some earlier models has been dropped, and some later models require at least 4.0.3c, 4.1.1, or Solaris 2.x.

SunOS took a shift starting with version 5.0, which changed its base from BSD to Unix System V Release 4, and became Solaris. The last release under the SunOS name was Version 4.1.4, released in November 1994.

The last version | Released: 2.11 | November 1994

2.11BSD – a BSD operating system based on and comes with several missing pieces that came after the 4.3BSD-Tahoe. 2.11BSD CSRG was the last edition of the DEC PDP-11 line system. This release is maintained Steven Schultz with a series patchlevel. It is the release of 4.4BSD-Lite, and requires the original UNIX license.

The system hasn’t been fit onto a non-separate I&D or machine without a floating point processor in a long time. Lots of overlay schemes need to be worked out; the floating point simulator in the kernel hasn’t been tested; sendmail won’t run on a non-separate machine, so bin/mail and ucb/Mail have to auto-configure not to use sendmail; csh is overlaid now even on a separate I&D machine, /lib/cpp is pushing the limit to handle all the #define’ing that is required to compile the kernel.

Due to the amount of software ported from 4.3BSD (and the Internet) he number of PORT directories has been cut down in order to fit the distribution on two 1600bpi tapes. Many of the sources not included are available from INTERNET archive sites, others will have to be acquired from a friendly 4.3BSD site.

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.
