These are some screenshots of NeWS 1.1 running on SunOS 4.1.4 on QEMU that I took time ago.
Unfortunately QEMU SPARC decided to break again. Also, keyboard doesn't work yet (forcing me to use the SunView terminal emulator), but probably it's due to the keyboard script.
In any case, SunOS 4.1.4 comes with OpenWindows out of the box.
