    New York! New York! hardware

    Games Supported:
        * New York! New York! (2 sets)
        * Waga Seishun no Arcadia

    Known issues/to-do's:
        * What does port A on IC37 AY8910 do?  It looks like a DAC, but
          this is not supported by the writes to the port.  All the
          writes are 0x9X, usually 0x9b or 0x9d.  Note that this is
          incorrectly referred to as port B on the schematics, but the
          pin #'s confirm it is, in fact port A.
        * What is the main CPU clock?  11.2Mhz / 16 goes through
          a MC4044 and a MC4024 analog chips before going to the EXTAL
          pin of the M6809

    Notes:
        * The Sigma set has Japanese voice samples, while the Gottlieb
          one is English
        * In cocktail mode New York! New York! programs the CRTC with an
          incorrect value.  Interestingly, when the Flip Screen DIP
          is set, the value programmed is correct.  This bug does not
          exist in Waga Seishun no Arcadia
        * The Crosshatch switch only works on the title screen
        * The Service Mode switch, which displays the total number of
          credits stored in the NVRAM, only works on the "Start Game"
          screen after a coin has been insered.  Hold down the key to
          display the coin count
        * The schematics mixed up port A and B on both AY-8910
