Inside the zip file are four files:
  216208 Nov 14  1985 ADVENTUR.EXE
  101234 Nov 14  1985 ADVTXT
    6390 Jun 26  1989 LIBRARY.DOC
     944 Oct 19  1989 VOLUME.DOC
You can run "ADVENTUR.EXE" in DosBox; despite being in with CP/M stuff,
it's a plain old DOS executable as far as I can tell.
Its version number is
  <Adventure/86-- Version:6.0/0, November 1985>
That is, this is Doug McDonald's MCDO0551.
