Year: 1981-1985
Hardware:
CPU = 1x SY6502 ; M6502 compatible.
CRCT = 1x SY6545 ; M6845 compatible mode. Doesn't seems that are using
; the first 4 bits of register R03 (HSync width).
SND = 1x AY8912 ; AY8910 compatible.

--- General Notes ---
Gaming Draw Poker:
Gaming Draw Poker, formerly known as Jack Potten's poker, is an evolution of the
mentioned game. It was created by Cal Omega in 1981 for Casino Electronics Inc.
Cal Omega was bought out by CEI (Casino Electronics Inc.), and CEI was bought by UCMC.
This game was made before the CEI 906iii system.
The game use the same GFX set that Jack Potten's poker for cards and have similar
layout, but the game is different and the old discrete pitched sounds were replaced
with a better set of sounds through a AY8910/12 implementation. The empty socket in
the pcb is maybe for future upgrades instead of sound ROM, since sounds are hardcoded.
Inputs are multiplexed and selected through PIA1, portB.
In game, use "Stand" instead of "Deal/Draw" to conserve all cards without discards.
To enter to TEST MODE press F2. Press "Discard 1" + "Discard 2" + "Discard 3" to exit.
To enter the STATS MODE press "Show Stats". Press "Deal/Draw" to exit.
To pass coin and hopper errors press "Hopper SW". Also keep it pressed to see the status.
For payout, press "Manual Collect" an then "Payout" for each credit (manual mode).
El Grande - 5 Card Draw:
This game was created by Tuni Electro Service and was licenced to E.T. Marketing,Inc.
This is the new version. The old one is still undumped, but looks like Golden Poker D-Up.
Flyer: http://www.arcadeflyers.com/?page=thumbs&db=videodb&id=4542
The AY8912 is mapped to 0x840/0x841 but the game lacks of credits and bet sounds.
The rest of sounds are ok. Maybe the missing ones are generated by discrete circuitry.
Inputs are multiplexed and selected through PIA1, portB.
There aren't meter and stats modes. Only for amusement, so... no payout.
To clear credits press F2.
To enter to TEST MODE press F2 twice. Press "Hold 1" + "Hold 2" + "Hold 3" to exit.

Dumper notes (old)
-- 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 :(

UPDATES
-------
[2007-09-15]
- Added sound support to "El Grande - 5 Card Draw".
- All crystals documented via #defines.
- All CPU and sound clocks derived from #defined crystal values.
- Splitted the driver to driver/video.
- Some minor input cleanups.
- Updated technical notes.
[2007-08-13]
- Added "El Grande - 5 Card Draw" (new).
- Constructed a new memory map for this game.
- Reworked a whole set of inputs for this game.
- Patched some bad bits in GFX rom d1.u68 till a good dump appear.
- Updated technical notes.
[2007-07-23]
- Cleaned up the inputs.
- Changed the hold buttons to "discard" since they are in fact discard buttons.
- Updated technical notes.
[2007-03-24 to 2007-04-27]
- Rearranged GFX in two different banks.
- Decoded GFX properly.
- Rewrote the memory map based on program ROMs analysis.
- Hooked two SY6520/6280 (M6821) PIAs for I/O.
- Hooked the SY6545 (6845) CRT controller.
- Fixed size for screen total and visible area based on SY6545 CRTC registers.
- Added partial inputs through PIAs.
- Added proper sound through AY8910 (mapped at $0840-$0841).
- Fixed AY8910 volume to avoid clips.
- Proper colors through color PROM decode.
- Demuxed inputs (thanks to Dox that pointed me in the right direction!)
- Added some game-protection workaround.
- Added NVRAM support.
- Renamed driver, set and description to match the real game.
