win 3.x was just text box no real graphics in them gui = graphic user interface all it did was play around with the screen colours and draw boxes around sets of lists. one friend of mine duplicated win3.x with his autoexec.bat file only. no using windows at all, but if you didn't know that you would have thought you were in win 3.x and in 90 whatever that win95 was released, they managed to dupilcate, barely, mac's original interface. mac came out in very early 80's I know was newst apple computer when I was looking at it in 82.
