AmigaOS and OS/2?

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.

What else could you do with the mouse? Could you launch any executable program by clicking on its icon, make menu selections with it, open folders and drives, move, delete folders by clicking/doubling clicking.  Hell. as late as 2007 I remember some well known Linux distro that wouldn't let you open to see the contents of a drive by double clicking its icon..

If it was drawn graphically, then it's definitely a GUI.

Hmm.  Is being not drawn by text characters enough to be a GUI.  Does it satisfy the "UI" in GUI ie being a "user interface" in addition to being graphic?  Where are the program icons and pull down menus?  Can I actually make the computer do things by issuing commands with the mouse pointer or do I have to fire up a shell and start issuing text commands? Is this a bit like Ubuntu's  half-arsed GUI implemetation where reliance on terminal commands is fundamental to its operation..
