Steve X contributes: "The GUI on SunOS in the mid 80's was never Motif, which was only released around 1989.
"SunOS originally came with SunView, and later Sun released an X-windows version called OpenLook. The first official Motif-based GUI shipped by Sun was on Solaris 2 and based on CDE, sometime in the 90's."
You are correct, of course. I must be concatenating time again ... It's a hazard of living long enough to become a crusty old fart, I guess :-) We did have Motif on SunOS before Sun officially shipped it ... Pre-Solaris, even. Not as early as SunOS2, but probably late 1889 or thereabouts (one of our devs came over from the fledgling OSF around then ... Sun was furious, and temporarily pulled our access to their source). Anyway, right around the SunOS 4.0.x/4.1.x boundary, definitely in the 4.3BSD era, but pre-SPARC (I don't consider the SPARCstation 1 to be a proper computer).
Steve adds: "I do vaguely remember such a superuser popup in SunView, but I'd have to boot my Sun 386i or 3/80 to check :)"
I'd check my always-on dual-pedestal 3/470 "Pegasus", but I chopped the GUI out of it almost 2 decades ago (not needed for running email, Usenet, ftp or those new-fangled Web servers), and besides it's too new for this conversation, running a much hacked & mangled OS that could be loosely called SunOS 4.1.3 U1B, if you squint at it ... Unfortunately, I sold my 2/170's power supply to a client in need about a decade and a half ago and haven't bothered replacing it yet ... One of these days I'm going to have to go thru' all my racks & scrap the junk that's not historically useful.
Pablo Mayfield scrive: "However, OSX is actually a registered UNIX apparently"
Not apparently. OSX is a UNIX. I know. Re-read mine.
Simon Banyard adds: "It's actually based on the Mach kernel from Carnegie Melon University"
Yes. The kernel is Mach ... but the system on top of it is comprised of a melange of the BSDs, with proprietary Apple derived stuff where appropriate.
And yes, the US patent system is broken. Beyond broken; it's decomposing.
