/***************************************************************************

 Scramble hardware


Interesting tidbit:

There is a bug in Amidars and Triple Punch. Look at the loop at 0x2715.
It expects DE to be saved during the call to 0x2726, but it can be destroyed,
causing the loop to read all kinds of bogus memory locations.


To Do:

- Mariner has discrete sound circuits connected to the 8910's output ports


Notes:

- While Atlantis has a cabinet switch, it doesn't use the 2nd player controls
  in cocktail mode.
