-This keyboard is very similar to FC660C hardware.
+This controler replaces original controller of Leopold FC980C and makes the keyboard programmable.
+
+Discuss this here: https://geekhack.org/index.php?topic=90681.0
+
+The keyboard is very similar electronically to its sibling model FC660C you can also refer this.
