I didn't know about FabBSD, which was a command line BSD for CNC machining, automation and instrumentation. It's been around until 2018, and was from Canada. It was based on 4.4BSD and OpenBSD.
BeOS was a single user operating system which was independently developed. It was created by a former Apple employee. BeOS lasted from 1991 until 2000. BlueEyedOS is a defunct derivative of BeOS which used an LGPL license. Other BeOS related operating systems and software both active and defunct can be found at: https://www.be.wildman-productions.org/index.php. Haiku is the most successful derivative of BeOS still around. BeOS based operating systems are BSD-like, not only in license.
Minix is no longer active, but its site is still up for educational and other software purposes. It is BSD-like, not only in license.
Based on NetBSD: EdgeBSD was a router BSD distribution, and BlackBSD was a security BSD operating system.
MirOS was based on OpenBSD, 4.4BSD and NetBSD. shells/mksh is a popular program from it. There's also editors/jupp. This operating system had a few alternative softwares such as: an archiver, MirMake, MirNroff and MIrCksum. It was headed by Thorsten Glaser who had disagreements as someone who previously worked on OpenBSD. It was only available for 32bit computers of x86 and Sparc.
HPBSD was an OS based on 4.3BSD, intended to replace HP-UX for HP printers. It became defunct in 1993.
RaspBSD was a desktop BSD for Raspberry Pi's and other SBC's. It was based on FreeBSD, and lasted until 2016.
PenBSD was a CLI interfaced BSD based on FreeBSD. It was for flash drives.
OliveBSD was live CD operating system based on OpenBSD, and it used IceWM as a desktop. It's last release was in 2006.
m0n0wall was a firewall and router BSD, which can still be used, even though it hasn't been updated since 2014. Still going m0n0wall forks aren't listed in this post.
t1n1wall was a firewall/router BSD based off of m0n0wall. It lasted until 2020.
smallwall was a firewall/router BSD which was based off of m0n0wall which lasted about a year.
SunOS by Sun Microsystems was actually a closed source BSD. SunOS lasted from 1982 until 1994. It shifted from BSD based to using Unix System V to evolve into Solaris in 1994. SunOS and Solaris weren't open source, but their description is important for understanding their history related to BSD's.
OpenSolaris of course was an open source Solaris based OS. It was the CDDL version of Solaris both released by SunMicrosystems. OpenSolaris' last release was in 2009 which it was discontinued in 2010 after Oracle bought Sun MicroSystems. Current versions of Solaris are closed sourced by Oracle. There are a few operating systems based on OpenSolaris. IllumOS and OpenIndianna are still active successors. OpenSolaris or IllumOS based is a different category of operating system than BSD, due to SunOS forming into Solaris. The IllumOS Foundation helps carry illumOS/OpenSolaris based operating systems and their common software repository.
