+
+
+    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.

-
-
-    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.

-
-    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
