Notes:
- Press 1P and 2P together to enter test mode.
TODO:
- CPU B continuously reads from 1e00. It seems to be important, could be a
scanline counter or something like that.
2009-03:
Added dsw locations and verified factory setting based on Guru's notes
(DSW3 not mentioned)
Boards:
- CPU/Video board labeled PWB(A)2000109B
- Sound board labeled PWB(B)3000154A
