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

Scramble memory map (preliminary)

MAIN BOARD:
0000-3fff ROM
4000-47ff RAM
4800-4bff Video RAM
5000-50ff Object RAM
5000-503f  screen attributes
5040-505f  sprites
5060-507f  bullets
5080-50ff  unused?

read:
7000      Watchdog Reset (Scramble)
7800      Watchdog Reset (Battle of Atlantis)
8100      IN0
8101      IN1
8102      IN2 (bits 5 and 7 used for protection check in Scramble)

write:
6801      interrupt enable
6802      coin counter
6803      ? (POUT1)
6804      stars on
6805      ? (POUT2)
6806      screen vertical flip
6807      screen horizontal flip
8200      To AY-3-8910 port A (commands for the audio CPU)
8201      bit 3 = interrupt trigger on audio CPU  bit 4 = AMPM (?)
8202      protection check control?


SOUND BOARD:
0000-1fff ROM
8000-83ff RAM

I/0 ports:
read:
20      8910 #2  read
80      8910 #1  read

write
10      8910 #2  control20      8910 #2  write
40      8910 #1  control
80      8910 #1  write

interrupts:
interrupt mode 1 triggered by the main CPU


Interesting tidbit:

There is a bug in Amidars. 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 seems to have 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.
