Hi moonyard and welcome to EAB!
You can find Yedorian Tales 1-3 (1 is only the shareware version though) on the EAB file server (
http://eab.abime.net/showthread.php?t=43633) in the folder 'User/TCD'. (credits go to Nostalgeek for this pack). I wonder if Muspar managed to get his hands on a full chapter 1.
