efaq: Emacs for MS-DOS

 
 8.8 Where can I get Emacs for MS-DOS?
 =====================================
 
 To build Emacs from source for MS-DOS, see the instructions in the file
 ‘msdos/INSTALL’ in the distribution.  The DOS port builds and runs on
 plain DOS, and also on all versions of MS-Windows from version 3.X
 onwards, including Windows XP and Vista.
 
    The file ‘etc/PROBLEMS’ contains some additional information
 regarding Emacs under MS-DOS.
 
    A pre-built binary distribution of the old Emacs 20 is available, as
 described at
 
    <ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/emacs.README>
 
    For a list of other MS-DOS implementations of Emacs (and Emacs
 look-alikes), consult the list of “Emacs implementations and
 literature,” available at
 
    <http://www.finseth.com/emacs.html>
 
    Note that while many of these programs look similar to Emacs, they
 often lack certain features, such as the Emacs Lisp extension language.
