   The magazine Open-Apple, in the January 1987 issue, has source code to   
   eject 3.5" disks on Apple 3.5 drives and UniDisk 3.5 drives.  You can   
   find an issue on Asimov at:   
      
   https://ftp.apple.asimov.net/documentation/magazines/open_apple/   
   pen%20Apple-Vol_2%20No_12-JAN_1987.pdf   
      
   Read pages 2.90 - 2.92.  The details of ejecting are near the end of   
   page 2.92.   
      
   I have the paper version of this magazine and I remembered it from back   
   then, so I looked it up.  Fortunately, it's scanned and in PDF form for   
   anyone to read.
