I understand that the first graphical user interface for SunOS was SunTools (later renamed to SunView), but I cannot find any documentation that states when it was released and for which versions of SunOS it was compatible with.

According to https://en.wikipedia.org/wiki/Sunos, Sun UNIX 0.7 had no windowing system, and SunOS 1.0 (November 1983) introduced the Sun Windowing System.

I think the first Sun machine I used was a 68020 running SunOS 2.0, which definitely had a graphical interface, so the above is at least consistent with my experience.

  • I can't remember if it X-Windows based. X-Windows came out in 1984. When I first saw the machine in 1987, it had a graphical interface that would lose track of itself every so often and redraw the windows from the bottom most to the topmost.

    SunView and NeWS weren’t X-based; the first Sun windowing system with X was OpenWindows IIRC. Commented Jan 27, 2023 at 11:12
  • @StephenKitt - wasn't NeWS the beautiful but somewhat impractical-on-that-hardware GUI that was based on Postscript?

  • @davidbak Display PostScript, what an interesting concept. Too bad it probably came both too early to be run with adequate speed and too late to get any kind of widespread adoption.

  • Sun certainly did use X Windows before switching to NeWS. In 1989 I used a Sun-2 with X Windows and SunView, without NeWS, and two years later I used a Sun Sparc with NeWS. So yeah, X Windows on Sun was definitely a thing.
