Z-code games in uncommon formats

From IFWiki

Most Z-code games are created for either version 5 or version 8 of the Z-machine, and as such, the names of their story files end in .z5 or .z8 respectively.

However, there are other versions of the Z-machine that are also available, although rarely used. This page lists some of those games.
