 *** SCO Unix and UnixWare
 
-**** SCO 3.2v4: Unusable default font.
-
-The Open Desktop environment comes with default X resource settings
-that tell Emacs to use a variable-width font.  Emacs cannot use such
-fonts, so it does not work.
-
-This is caused by the file /usr/lib/X11/app-defaults/ScoTerm, which is
-the application-specific resource file for the `scoterm' terminal
-emulator program.  It contains several extremely general X resources
-that affect other programs besides `scoterm'.  In particular, these
-resources affect Emacs also:
-
-        *Font: -*-helvetica-medium-r-*--12-*-p-*
-        *Background:                    scoBackground
-        *Foreground:                    scoForeground
-
-The best solution is to create an application-specific resource file for
-Emacs, /usr/lib/X11/sco/startup/Emacs, with the following contents:
-
-        Emacs*Font:     -*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
-        Emacs*Background:       white
-        Emacs*Foreground:       black
-
-(These settings mimic the Emacs defaults, but you can change them to
-suit your needs.)  This resource file is only read when the X server
-starts up, so you should restart it by logging out of the Open Desktop
-environment or by running `scologin stop; scologin start` from the shell
-as root.  Alternatively, you can put these settings in the
-/usr/lib/X11/app-defaults/Emacs resource file and simply restart Emacs,
-but then they will not affect remote invocations of Emacs that use the
