The VR177X-02 fully supports the functionality of the WD1770/WD1772/VL1772 floppy drive controllers but specific hardware implementations (especially those that rely on undocumented, or out of specification, attributes for the original controller) may give inconsistent results. Compability testing is ongoing so please contact [email protected] to check if your application or hardware is supported.

For detailed specifications and application notes please refer to the datasheet
