Floppy Drive Interface
The SCH3114I-NU (U15) chip provides the floppy controller and supports one floppy drive. The floppy
signals are provided through a standard 34-pin header (J17). The floppy controller will support a 360k,
720k, 1.2M, 1.44M, or 2.88M drive.
The floppy drive header provides 34 pins, 2 rows, odd/even sequence (1, 2) with 0.100" (2.54mm) pitch.
