+
+This is the original controller for the Microsoft Windows releases. This controller has two handles (5 power notches and 8+emergency brake notches) and 3 buttons (A, B, C).
+
+The buttons and handles are mapped to game port buttons and axes, respectively, as follows:
+
+| Game port   | Controller |
+|-------------|------------|
+| B1          | B          |
+| B2          | A          |
+| B3          | *Unused*   |
+| B4          | C          |
+| X1          | Brake      |
+| Y1          | Power      |
+| X2          | *Unused*   |
+| Y2          | *Unused*   |
+
+The controller needs to be calibrated before it can be used.
