  I wonder if this would have been a big concern for home computer vendors at the time. How many of them would have used Unix? Even if they had, would Unix even have been popular enough to really matter?

  At that time Apple chose CR, UNIX was just one of a multitude of minicomputer operating systems. Compatibility with it would have been only important in hindsight.
