DriveRDY is a small interface that generates the READY signal necessary for proper operation of any 3.5" PC drive to work with Amiga.

The adapter is designed so that the signal is exactly accurate, as it is present in original Amiga drives. To achieve this result, the author used reverse engineering to capture the logic level of the Chinon BZ-354 mechanics.

DriveRDY is equipped with CMOS logic gates 74HCxxx. Those ICs have a very low current consumption, so there is no need for an external power source, as they are powered from the floppy drive itself. Similar hardware solutions already exist and can be bought on eBay. To our disappointment, they are copies of copies, from documentation freely published on the Internet, unfortunately not fully functional.

Adapter was tested with several PC floppy drives from various manufacturers (Nec, Sony, Epson, Teac, Samsung, Chinon, Panasonic, etc.), more than 40 different models in total.

DriveRDY works in DD mode!

DISCLAIMER

The adapter has one limitation, with some FDDs it is not possible to use the adapter because it overlaps the power supply connector of the floppy drive. Some drives have it right above the flat data cable connector and the DriveRDY adapter covers this part. These are some models like Alps or Mitsumi. Please check your drive before buying the adapter.

 The floppy drive itself is not included.
