bit 0-2 coins per play
dsw2: (bootleg version, the original version is slightly different)
bit 7 cocktail/upright (1 = upright)
bit 6 ?

6830 Watchdog reset?
7000- custom IO chip parameters
7100 custom IO chip command (see machine/galaga.c for more details)
a000-a002 starfield scroll direction/speed (only bit 0 is significant)
a003-a005 starfield blink?
a007 flip screen
Interrupts:
CPU #1 IRQ mode 1
NMI is triggered by the custom IO chip to signal the CPU to read/write
parameters
CPU #2 IRQ mode 1
