Circuit of the floppy disk interface. Not the usual circuit based upon a well-known FDC controller IC, but a simple and not so standard solution. The OS65D operating system from OSI, Ohio Scientific, knows how to handle this interface well, and just for this purpose, Elektor choose this solution.
The next page gives information on OS65D, the operating system.
