I doubt that it is humanly possible to fill up a 2gb scsi drive in a Classic II, with all the 68k software in the world that would actually run tolerably well on it, so I'd say, save yer adapters for another machine and buy a largish scsi hd and be done with it.

And I'd advise reading the online piece on how to make 7.5.5 like 7.1 if you are really going to shoehorn it into a CII. Why make a nice machine run like a 400lb 50 year-old with all that overhead?
