    Sega G-80 raster hardware

    Games supported:
        * Astro Blaster
        * Monster Bash
        * 005
        * Space Odyssey
        * Pig Newton
        * Sindbad Mystery

    Known bugs:
        * Pig Newton doesn't read cocktail controls (might be game bug)
        * Astro Blaster v1 dies when you first start

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

    The Sega G-80 system is an interchangeable raster/vector system with
    a common main board and a stack of video/sound boards for each game.
    The CPU boards were protected with the famous G-80 security chips,
    which scramble the address lines on memory writes. Below are a list of
    games and their board stacks:

    Astro Blaster:
        * G-80 CPU board (315-0062 security)
        * G-80 2716 EPROM board
        * Video I board
        * G-80 Speech Synthesis Board
        * Astro Blaster Sound board (discrete)

    005:
        * G-80 CPU board (315-0070 security)
        * G-80 2716 EPROM board
        * Video I board
        * 005 Sound board (melody generator + DAC, discrete)

    Space Odyssey:
        * G-80 CPU board (315-0063 security)
        * G-80 2716 EPROM board
        * Video I board
        * Space Odyssey Background Generator Board
        * Space Odyssey Sound board (discrete)

    Monster Bash:
        * G-80 CPU board (315-0082 security)
        * G-80 2716 EPROM board
        * Video I board
        * Monster Bash Background Board
        * Monster Bash Sound Board (N7751+DAC, TMS3617, discrete)

    It appears that later on in the evolution of the hardware, Sega
    produced a 2-board version of the hardware which put all the CPU,
    EPROM, video, and background hardware on one or two boards:

    Monster Bash (2 board):
        * G-80 consolidated boardset (315-5006 encrypted Z80)
        * Monster Bash Sound Board (N7751+DAC, TMS3617, discrete)

    Pig Newton:
        * G-80 consolidated boardset (315-0062 security)
        * Sega Universal Sound Board (I8035, discrete)

    Finally, it looks like Sega also evolved the hardware in the
    direction of their widely-used System 1 hardware. The final G-80
    game had a new sound board that was SN76496-based and seemingly
    identical to the final System 1 hardware. It also used an encrypted
    Z80 CPU very much like the System 1 games (the 2-board Monster Bash
    also used one of these):

    Sindbad Mystery:
        * Unknown boardset (background doesn't match consolidated)
        * System 1 Sound (Z80, 2xSN76496)

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

    See also sega.c for the Sega G-80 Vector games.

    Many thanks go to Dave Fish for the fine detective work he did into the
    G-80 security chips (315-0064, 315-0070, 315-0076, 315-0082) which provided
    me with enough information to emulate those chips at runtime along with
    the 315-0062 Astro Blaster chip and the 315-0063 Space Odyssey chip.

    Special note (24-MAR-1999) - Sindbad Mystery does *not* use the standard
    G-80 security chip; rather, it uses the Sega System 1 encryption.

    Thanks also go to Paul Tonizzo, Clay Cowgill, John Bowes, and Kevin Klopp
    for all the helpful information, samples, and schematics!

    TODO:
    - verify Pig Newton and Sindbad Mystery DIPs
    - attempt 005 sound
    - fix Space Odyssey background
    - figure out why Astro Blaster version 1 ends the game right away

    26/3/2000:  ** Darren Hatton (UKVAC) / Adrian Purser (UKVAC) **
                Added a 3rd Astro Blaster ROM set (ASTROB2).
                Updated Dip Switches to be correct for the Astro Blaster sets.
