Main CPU
--------
0000-3fff  ROM
4000-5fff  RAM
b000-b07f  sprite ram
b400       command for sound CPU
b500-b505  input ports
b506       screen flip off
b507       screen flip on
b600-b61f  palette ram
b800-bbff  video ram
bc00-bfff  color ram
c000-ffff  More ROM

Sound CPU (appears to run in interrupt mode 1)
---------
0000-0fff  ROM
1000-1fff  ROM (Zzyzzyxx only)
4000-43ff  RAM
6000-6fff  R/C filter ???

I/O
---
0x40: Read - ay-8910 port 0
      Write - ay-8910 write
0x80: Write - ay-8910 control

The 2 ay-8910 read ports are responsible for reading the sound commands.
