[comp.sys.mac] Xerox/Mac/??? Interface question

folta@tove.umd.edu (Wayne Folta) (12/31/89)

In the long-running discussion about who gets credit for what, someone
mentioned that icons first (or at least very early) appeared at PARC,
then showed up in the Mac Finder.  I would like to know more details
about this.  As I see it, there are three things that could be lumped under
the term "icons":

   1. Iconic representation of files (ala Mac)
   2. Iconic representation of closed windows (running processes) (ala Sun)
   3. Automatic selection of a program to process a file when the file
      is selected (ala Mac and even Windows)

Does anyone out there have more info on the earliest appearance of each
of these concepts?
