ConanTheBald: Does anyone know?
Yes.
If you buy the 2004 Bard's Tale game, it includes the option to play the classic trilogy. Once you start the trilogy this way, you will find the disk images somewhere on the computer to use with the emulator of your choice. (I don't remember where the images are stored.)
This will give you the Apple 2GS versions of Bard's Tale 1 and 2 and the Apple 2 version of Bard's Tale 3. Having played these versions, I would say that they're all good versions of these games. (Apple 2 BT3 is *far* better than the DOS version, as that version just has too many bugs for me to recommend, and they tend to be bugs that make the game less fun and less interesting.)
