    COINMASTER-GAMING - VGA BOARD
    -----------------------------

    Preliminary driver by Roberto Fresca & Angelo Salese.


    Games running on this hardware:

    * Colorama (standalone),   199x-2001,  Coinmaster-Gaming, Ltd.
    * Roulette (bet station).  199x-2001,  Coinmaster-Gaming, Ltd.
    * Keno, (bet station).     2000-2001,  Coinmaster-Gaming, Ltd.



*******************************************************************************


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

  This board is used in each bet station of Coinmaster's Roulette and Keno game.
  Both systems have a phisical electromechanical unit with their own controller
  plus sound. The central units (wheel controller) are routed to the bet stations
  (10 for default) through 2 different kind of networks, depending the wheel system.

  There are 2 multisystems types:


  - System RWC (Roulette Wheel Controller)

  The old version. The central unit is tied to a controller and then routed to
  the bet stations using a custom serial network with RJ9 connectors and regular
  phone cable. Also has a thermal printer attached.


  - System Y2K (Year 2000)

  The newer system. The central unit has 4 trays inside with power supply, roulette
  controller, and a custom HUB board. All the system is interconnected through
  regular RJ45 CAT5 cables from the hub board. Also has a thermal printer attached.


  All systems are controlled through a touch screen.


  Colorama is a standalone roulette system, driven by one VGA board. It has a big lamps
  loom, and a vertical positioned roulette painted on the marquee with one phisical arm
  pointing to the numbers.
