- I have looked at the IWM pinout description in tn-misc-006 and read
- descriptions of the 5.25" disk drive, Unidisk 3.5 Smartport and everything
- else I could find but have never been able to find out what the controller
- does to cause an Apple 3.5 to eject. The only additional signal the 3.5
- has over the 5.25 is the head select. How then can the drive be told to
- eject the disk?
-
- Additionally, what precisely is the difference between the Macintosh 3.5
- interface and the Apple 3.5 interface (apart from the pulse width modulation
- signal required by the old 400k drives)?
-
- Thanks in advance to anyone who can answer either question.
-
- Happy 1993.
