The signal on pin34 differs between floppy drives model:
*For 3inch floppy drives, it is a "Ready" signal. The RDY signal is sent whenever a disk is installed and rotating at correct speed in the drive.
*For 3.5inch floppy drives or Gotek, it is a "Disc Changed" signal. The DC signal determines whether the same disk loaded during the previous disk access is still in the drive.
