Revision as of 21:21, 13 January 2014 by Samiam (http://zzo38computer.org/zmachine/aimfiz.zip supports v9 and v10)
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. The only known Z machine interpreter that support these versions is a version of Aimfiz (download link)
