*For 3inch floppy drives (pin26), it is a "Ready" signal. The /RDY signal is active whenever a disk is installed and rotating in the drive.

Other solutions exist to Alternatively, you can [[Modify PC floppy drives]] to recreate create a Ready signal. Also, or use Amiga floppy drives, which already have this signal. Gotek drives (with a FlashFloppy or HxC firmware) can also be configured to simulate the Ready signal.
