Revision as of 20:32, 13 January 2014 by Samiam (Everything supports z7 and z8; is there anything that supports z9 or z10?)
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.
