AmigaOS and OS/2?

[kolla]

Only rexx the scripting language in common.

Yes - and only the language, not the interpreter. ARexx has lots of amiga specific features, I would guess that the OS/2 rexx interpreter also has lots of OS/2 specific features.

What I'd like to know is how much MS copied Amiga for Windows 95.

That's easy - nothing.

NEXTSTEP operating system, 1986
Arthur operating system, 1987

Apple got their dock thru NEXTSTEP btw ;-)

And "big buttons" as such has nothing to with Magic Workbench - those are ToolManager docks. Sources are available, allthough only for educational purposes, according to readme.

Does this qualify as a "desktop" to you?

If so, then yes, there were "UNIX desktop" in 1985, and this was also running on 68k btw. Yes, I know the above shot is newer, but I have seen older ones, and they were similar and typically black&white.

We (and by "we" I might mean just me) called thos "TUIs" for Textual User Interfaces.

Just you then, TUI is something else, like ncurses etc. These things sold as graphical workstations, the user interface is not "drawn" using "characters", and yes there was a mouse and you could move/resize the windows.

Considering amiga has a compression tool called LZX, which one you'd think?

Not really relevant since LZX never was part of AmigaOS.
