+ Notes: 15 Feb 2007 - MSH
+ * Real Millipede boards do not have the Joystick circuit hooked up
+ to the card edge.
+ * The Joytick and T-Ball inputs are both swapped through LS157s by
+ the CNTRLSEL signal at 0x2507.
+ * How do we hookup TBEN signal at 0x2505?
+
+ Changes: 15 Feb 2007 - MSH
+ * Added corrected memory map and dip switch settings from Atari Manuals.
+ * Added Cocktail mode (based on v0.36.1 driver from Scott Brasington)
+ * Removed unused dip toggles, now set to IPT_UNKNOWN
+ * Hooked up 2nd trackball
+ * Map P2 Joy inputs to work correctly. (They don't work on a real board)
