It is funny that people mostly remember Norton Commander while it came very late in msdos history. Back in 1987 we were using Microsoft Dos Manager on our intel 8088 that was doing pretty much the same thing already, offering a dual pane.

(F9 to split panes, options menu allow to change color scheme)
