    History:
    ========

    In 1975, Si Redd founded A1-Supply.  This was renamed to Sircoma in 1978,
    and eventually IGT (International Game Technology) in 1981.

    Along the way, in 1978, Fortune Coin Company was acquired and contained
    the basis to their Fortune I game machines.

    The Fortune I hardware consisted of the following games:
      Regular Draw Poker
      Progressive Draw Poker
      Joker Wild Draw Poker
      Double Up Draw Poker
      Credit Draw Poker
      Lucky 7 Poker (Seven Card Stud Poker)
      Regular 21 (Blackjack)
      Live 21
      Count Down 21
      Two Hand 21
      In Between
      Regular Slot
      Credit Slot

    InterFlip (Spain), is a subsidiary of Recreativos Franco.
    This company was created mainly with the purpose of manufacture
    and distribute export-class games.

    These machines were build in upright wood style cabinets, and compliment
    with class "C" (for casinos) spanish gaming regulations.
