I've been looking for a copy of that game for a while now. Is there an online version or a z(5,8) version I can run with frotz or something? Is it even in the public domain?
Well, if the copyright gods will forgive me, it should be in this collection, which I can find no particularly legal way to purchase in a way that gives money to any rightsholders: http://www.myabandonware.com/game/the-lost-treasures-of-info... I don't know, but it is likely the core z5 files can be found in there with a bit of hunting.
The first Lost Treasures of Infocom is legally available for the iPhone: https://itunes.apple.com/us/app/lost-treasures-of-infocom/id... Though, bizarrely, not for Android.
Is it still possible to buy hard copies of games from Infocom? Or are they all lost relics now?
