   Question about Disk II Emulation (.woz,

   Hi there,   
      
   I'm writing an Apple II Emulator. It boots up perfectly and enters Applesoft.   
   Basic Programs are working fine. To test the sound and graphics, I want to   
   emulate a Disk Drive to be able to load some of the old games and I am quite   
   confused at the moment.   
      
   I found out during boot up the Disk II firmware makes heavy use of   
   softswitches - so far, so good.   
      
   Where I am stuck is: How do I get a "disk image" in my emulation? Which format   
   must it have? Woz? DSK? Up to know I know "that these formats exist". How can   
   I deal with these formats? What do I have to consider?   
      
   How do I "read out" these images to satisfy the emulation and give it the   
   bytes it wants to make the boot up complete?   
      
   I don't want  just to look up someone else's source code - I want to   
   understand at an more abstract level, what's really going on and start a   
   conversation on this topic.   
      
   Cheers,   
   Jens
