There are at least 10 different versions of the Z machine out there:

  • Versions 1-6 Created by Infocom in the 1980s
  • Graham Nelson made some minor changes in the 1990s to allow for larger story files, creating versions 7 and 8 of the spec. Most, if not all, modern Z machine interpreters support v7 and v8 story files.
  • Zzo38 has more recently created versions 9 and 10 of the spec, with a number of extensions allowing even larger story files, finally giving Z-machines XOR support, and many other changes. There are no known Z machine interpreters that support these versions of Z-machine files.
