   The crystal seems ok and this clock makes it throught to pin 34 of the MPU.
   I was expecting that PHASE 03 - pin 22, should be clocking, but it simply sits at 5v.

   *** Game Notes ***
 
-  Just insert credits, and play. :)
+  Just insert coins, and play. You can win up to 500 credits! :)
 
   A default NVRAM is provided. Without it, the game stucks at boot with a memory error
   screen. If this happens, press the key 9 (Attendant). The game will initialize the NVRAM
   and then boots OK.
 
-  The RESET service button (key R) is just for payment purposes.
+  The RESET service button (key R) is just for clean credits purposes.
 
   The Supervisor Key (Key 0), brings a menu for bookkeeping, and replay (still can't see
   the point). The key behaves like a real lock key, with off/on status.
 
+  From the marquee: 'ALL CREDITS REDEEMABLE IN LIQUOR ONLY. NO CASH PAYMENTS'
+  So we can assume that is *exclusive* for amusement.
+  
+  From the marquee: 'MINIMUM REDEMPTION: 30 CREDITS' (to redeem LESS THAN 30 CREDITS,
+  Player must insert coins to bring total Credits to 30).
+
+  Ok... you need to have 30 or more credits to redeem. Otherwise you oddly need to insert
+  more coins to reach the minimum of 30 Credits.
+
+  To redeem credits (30 or more!):
+  1) Press the Hand Pay button (key 8). You'll get the 'Call Attendant' blinking message.
+  2) Press the Attendant button (key 9). You'll get a new message at bottom-left of the
+     screen about the amount of credits to pay.
+  3) Turn ON/OFF the Supervisor key (key 0). It will clear the credits, with a new message
+     at bottom-left of the screen about of value paid.
+
+
+  Paytable:   Play 1 to 5 coins....
