91:  Where can I get Emacs for my PC running MS-DOS?

  Emacs 19 (versions 19.23 and later) should compile right out of the box
  on PCs with a 386 or better, running MS-DOS 3.0 or later. You will need
  the following:
  
  Compiler: djgpp version 1.11 maint 4 or later.  You can get the latest
            version by grabbing everything you see at:

            ftp://oak.oakland.edu/pub/msdos/djgpp

  Tar:  One DOS version of tar is available at

        ftp://ftp.urc.tue.nl/pub/unixtools/dos

        However, not all DOS versions of tar work equally well, so you
        might have to try others if this one gives you trouble.  The
        versions known as tar4dos.zip and ltarv3.zip are also supposed to
        work, as well.

  Utilities: chmod, make, mv, sed, rm. 

             All of these utilities are available at:

               ftp://ftp.iro.umontreal.ca/pub/Internet/gnuish

             You should grab the files futil4ax.zoo (contains chmod.exe,
             mv.exe, and rm.exe), sed106ax.zoo (contains sed.exe), and
             gzip07ax.zoo (contains gzip.exe).

  The file etc/MSDOS contains some information on the differences between
  the Unix and MS-DOS versions of Emacs.

  If you would prefer not to compile Emacs by yourself, you can get
  binaries for Emacs 19.24 at

      ftp://ftp.demon.co.uk/pub/ibmpc/editors/emacs19.24
      ftp://ftp.imada.ou.dk/pub/mirrors/msdos/emacs-19.24

  OEmacs (see question 92) also runs under MS-DOS.

  For a list of other MS-DOS implementations of Emacs (and Emacs
  look-alikes), consult the list of "Emacs implementations and literature,"
  available at

    ftp://rtfm.mit.edu/pub/usenet/comp.emacs

  Note that while many of these programs look similar to Emacs, they often
  lack certain features, such as the Emacs Lisp extension language.
