>Does the amiga have an emulator for Apple II stuff?
I don't know about the Apple II, but certainly the 68k Apple Macs with Fusion and Shapeshifter.
The C64 is also fairly well emulated with Frodo and Magic64.
If you like those old text adventures you may be able to play them on the Amiga anyway. Level 9 did their version of Colossal Cavern and there was the Silicon Dreams trilogy and many other games. There's also an IF (interactive Fiction) archive with cross platform data, and the Amiga has a player for these - Aminet, I reckon.
