re: "I would like to write a Starbase application which works on hp2393a,
     hp2397a, hp2623a and hp2627a terminals.  This application needs to
     have two screen regions: a graphics region and a scrolling dialog
     region  The screen layout looks like this:"

I suggest implementing the scrolling dialog region by using text memory
lock.  If you set ML on a screen empty of text, new text written to the
ordinary tty port will scroll out of sight at the point indicated.
