After taking a look at OS/2 1.1, here is really quick look at IBM OS/2

The "OS/2 System Editor" is a text editor almost exactly like Notepad.
OS/2 1.1 did not have this or any other PM applications.
Among several new Presentation Manager applications, OS/2 1.2 includes
a GUI based disk partition utility.
