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

Universal board numbers (found on the schematics)

Cosmic Guerilla - 7907A
Cosmic Alien    - 7910
Magical Spot    - 8013
Magical Spot II - 8013
Devil Zone      - 8022

TODO:
- double check irq sources via schematics

2008-08
Dip locations verified with manuals for all the games.


Note on Coinage DSW (devzone and magspot only):

According to manuals, coinage settings (see "DSW" port) should be set by
a physical DSW B but only read when SWA:3,4 are both set to OFF. Currently,

* In magspot, SWA:3 affects the number of lives & SWA:4 seems to have no
    effect
* In devzone, setting SWA:3,4 on anything but OFF,OFF results in no coins
    accepted at all
