Adventure in Serenia is a dos game... You only need to use DOSBox.
I won't tell you where to get it however, as that would be 'piracy'. That being said its not that difficult to find.
As for legal versions of most of the games you mentioned, the last time they were officially released was in the Roberta William's collection, although King's Quest Collection released around the same time also has a few of them.
The above link has many of the apple II and Apple IIGS versions though emulated... Who knows for how long, if people keep linking to it, and let activision know it exists

. Kinda like how they went after Sarien.net...
