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

Taito  'O System'
-------------------

Taito gambling hardware, very similar to H system.

Board specs (based on poor quality pic):

68000
YM2203
4 custom Taito chips ( TC0080VCO? TC0070RGB? )
Custom (non JAMMA) connector
Battery


Games :

Parent Jack  (C) 1989 Taito

TODO:

- inputs (coins)
- NVRAM
- sprite priorities
- dips
- interrupts (sources) - valid levels 4,5,6(hop empty?)
