Improvements to CEI 906 III system. [Roberto Fresca]

Browse Source 
* Corrected docs about the 906III memory map.
  * Mapped the AY8912.
  * Added AY8912 proper interfase. Tied SW2 to AY8912 port.
  * PIA0, portA is polled constantly. Tied some debug handlers
     to understand how the input system works.
  * Added notes about the PIAs R/W.

-- Gaming Draw Poker --------------------------------------------------------
Program roms are roms 23*.*, on the board, there is a number near each roms
looks to be the address of the rom :
23-91 1800
23-92 2000
23-93 2800
23-94 3000
23-9 3800
Graphics are in roms CG*.*, there is no type indication on these rams, i hope
i read them correctly.
There is also 3 sets of switches on the board :
SW1 1 300 SW2 1 OPT1
2 600 2 OPT2
3 1200 3 OPT3
4 2400 4 OPT4
5 4800 5 OPT5
6 9600 6 DIS
7 - 7 +VPOL
8 - 8 +HPOL
SW3 no indications on the board
The sound rom is missing on the board :(
