Jim Sather's "Understanding the Apple IIe" has a wonderful exposition on the workings of the Apple II disk controller. Without having an Apple II at my disposal in the 80s, I was able to construct a rather simple ISA card for a PC that would read Apple floppies. Then I got a MatchPoint PC card. Now, of course, handling Apple II floppies can be done with $3 microcontroller card. --Chuck
