  Hardware Notes:
  ---------------

  PCB etched:

  HERBER LTD
  Jubilee Sales Pty Ltd.
  BD No V63-261 ISS1.

  1x TMS9980 CPU.
  1x MC6845P CRTC.

  1x TC5517AP-2 (2048 words x 8 bits Asynchronous CMOS Static RAM), tied to a battery.
  1x 2114       (1024 words x 4 bits RAM).

  3x 2732 labelled 1, 2 and 3.
  3x 2764 labelled Red, Blue and Green (the last one also has '22-3-85').

  1x 6.0 MHz crystal.
  1x Panasonic BR-2/3A lithium battery (3V, 1200 mAh).


  From some forums...

  The memory chips on board are the toshiba TC5517ap powered via the Lithium cell and
  the 2114 find the 74148 or 74ls148, all 9980 cpu's use one, pin3 will generate a reset.
  The 5517 ram is compatible with 6116 or 2018.

  The 9980 has 3 interrupt inputs, but they are binary.
  The ls148 encodes the interrupts to the cpu - the highest interrupt is reset.

  I tried pulling pin 3 of the 74ls148 low and yes, this sets up the reset interrupt
  on pins 23, 24 and 25. The TC5517 checks out ok as a 6116.

  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 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 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....

  DRIVER UPDATES:


  [2014-02-19]

  - Added a default clean NVRAM.
  - Found and implemented the credits input.
    The game is now working!. Still no sound.

  [2014-02-17]

  - Demuxed the input system.
  - Hooked an cleaned all inputs, except the coin in (missing).
  - Added NVRAM support.
  - Hooked CRTC properly.
  - Adjusted the screen size and visible area according to CRTC values.
  - Adjusted the screen pos 8 pixels, to get a bit centered.
  - Fixed palette to 8 colors.
  - Added technical notes.

  [2014-02-17]

  - Corrected the crystal value and derivate clocks via #DEFINE.
  - Improved memory map.
  - Hooked the CRT controller, but the init sequence seems incomplete.
  - Created the accurate graphics banks.
  - Found and mapped the video RAM.
  - Hooked the ATTR RAM.
  - Assigned the correct graphics banks to the proper drawn tiles.
  - Find and mapped an input port.
  - Started a preliminary workaround to demux the input port.
  - Added technical notes.

  [2010-09-05]

  - Initial release.
  - Decoded graphics.
  - Proper tile colors.
  - Hooked the correct CPU.
  - Preliminary memory map.
  - Added technical notes.


  TODO:

  - Analize the remaining CRU writes.
  - Discrete sound?.
  - Check clocks on a PCB (if someday appear one!)
