I bet few people ever used it, but I actually did for a short time. There has been an X11 / "regular Unix" implementation of #OpenStep besides GNUstep: for Solaris (Sun's OS at the time).

@helge Was there ever a version of OpenSTEP for Solaris that was compiled as x86 (or ppc…) binaries as the diagram seems to indicate? So far, I’ve only seen the Solaris/SPARC version.
@me_ I’ve used it on x86. I wonder whether I could find the install media for that. It was a long time ago and I don’t remember how I installed it.
@me_ I’m not a 100% sure but I think you could even do nxhost with that X11 DPS
@helge Somebody on the nextcomputers.org forums got NXhost to work with OpenStep for Windows a couple of months ago, but that was rather fragile I think.
@me_ But still, OpenStep for Windows also included DPS 🙃
@helge Yes, of course, but I think NXhosting was never officially supported on the NT version.
