A lot of 90's stuff ran great on SunOS 4.x!

  Yes, but SunOS 4 was both extremely popular (enough that a lot of software had explicit support for running on it) and implemented a decent amount of System V and POSIX compatibility! Probably most notably, it implemented SysV shared memory (sys/shm.h) plus messages/semaphores, STREAM support, SysV termio, SysV libcurses, and probably others I'm not aware of. I'm not sure how much any of these helped run software, but it bears pointing out anyway.

    Very true. SunOS 4.x is still my favorite 90's Unix. I had a Sun 3 box for a while, then got a low end Sparc Station at home! Eventually in the late 90's I gave in and installed Solaris. 2.4 and earlier was kinda rough, but it was pretty decent by 2.5.
