/*  - The Taito Space invaders hardware comes on at least five board types;
      The Taito manufactured ones are:
      * The "L-shaped" PCB set, Upright, B&W only
      * Three pcbs in a stack, often called the '3 layer pcb set' (most common)
      * Two pcbs in a stack, with the function of two of the three pcb stack
        pcbs combined.
      * In general, discounting revision specific differences, the pcbs are
        arranged in a stack, connected end-to-end by ribbon cables and folded
        such that the middle pcb (of 3 pcb stack) or the bottom pcb (of 2 pcb
        stack) is upside down.
      * Keep in mind specific differences on the pcbs (especially the TVN pcbs
        vs the others) sometimes prevent exchanging 'equivalent' pcbs between stacks.
        * L-shaped pcb set details:
          * One large, square board with ROM, RAM, CPU, Video circuitry on it.
          * One smaller pcb with audio/io/shifter circuitry on it, plugged into
            the main pcb at a right angle (hence the entire pcb set is 'L-shaped')
          * Does not have the capability of any sort of electronic color overlay.
        * 3 layer pcb set details:
          * This pcb set came in 3 versions: TVN, CVN, PVN; see below for differences.
          * Top pcb: Audio/IO/Shifter pcb
            - discrete audio and sn76477, and volume knobs
            - data shifter, using either ~11 74xx chips, AM25S10s, Fujitsu MB14221
              or Fujitsu MB14241 chips, which all do the same thing.
            - has the dipswitches
            - has the main "G" edge connector for the wiring harness
            - has the gating circuitry for the color overlay
              (these are not present and/or populated on some TVN pcbs)
            - despite there being at least six versions of this pcb, the discrete
              audio section is identical in all of them.
          * Middle pcb: CPU/RAM/Color overlay pcb
            - has SRAMS on it
            - has the 8080 CPU on it
            - has the two PROMS for color overlay on it (one for each player flip)
              (these are not populated on TVN pcbs and the related circuitry is not
              present and/or populated on some TVN pcbs)
          * Bottom pcb: Power/Video/ROM pcb
            - has the game roms on it
            - has the main B&W video generation logic on it
            - has the larger connection to the PSU, and B&W composite output "T" connector
        * 2 layer pcb set details:
          * This pcb set came in one version: PVN, and is entirely exchangable
            with the 3 layer PVN pcb set.
          * Top pcb is same as 3 layer pcb set
          * Bottom pcb combines the function of the Middle and Bottom pcbs
            of the 3 layer set.

       * The different pcb set versions are noted by a different version code on
         a paper sticker on the pcb; The code will be of the format mVNnnnnn where
         m is a letter and nnnnn is a number.
         Codes:
         * SVNxxxxx? (L shaped pcbset) - B&W only, used on "Space Invaders" Upright
           with 3-strip overlay.
           Audio PCB daughterboard has part number SVN00001 or SVN00003.
           Came from factory with one of the TV romsets ONLY?
           Capable of running TV, SV or CV romsets.
         * TVNxxxxx (3 layer pcb) - B&W only, used on "T.T Space Invaders"
           cocktail with blended single-sheet color gel overlay.
        TODO: this overlay is not supported in MAME yet.
           Several revisions (at least 5 rom, 3 cpu, 3 audio) of each pcb exist
           for this set.
           Came from factory with one of the SV or TV romsets.
           Capable of running TV, SV or CV romsets.
         * CVNxxxxx (3 layer pcb) - Color, used on "T.T Space Invaders Color"
           cocktail with electronic overlay.
           Came from factory with one of the CV romsets.
           Capable of running TV, SV or CV romsets.
         * PVNxxxxx (2&3 layer pcb) - Color, used on "T.T Space Invaders Part
           II" cocktail with electronic overlay.
           Several revisions (at least 3 rom, 1 cpu, 2 audio) of each pcb exist
           for this set.
           Came from factory with UV (2708) or PV (2716) romsets.
           Capable of running TV, SV, CV, UV or PV romsets.

       * The following Romsets are known:
         TV0H, TV02, TV03, TV04 (w/test mode) - sitv
         TV01, TV02, TV03, TV04 (w/o test mode) - undumped, tv01 has crc32 of 9F37B146
         SV0H, SV11, SV12, SV04, SV13, SV14 - undumped? roms called sv0h exist in mame...
         SV01, SV11, SV12, SV04, SV13, SV14 - sisv2
         SV01, SV02, SV10, SV04, SV09, SV06 - sisv
         CV03, CV04, CV05, CV06 w/proms - undumped (but apparently the same as sisv with the roms combined to 2716 size)
         CV17, CV18, CV19, CV20 w/proms- sicv
         UV1, UV2, UV3, UV4, UV5, UV6, UV7, UV8, UV9, UV10 w/proms - undumped (probably same as pvxx set just split differently)
         PV01, PV02, PV03, PV04, PV05 w/proms - invadpt2

      - Midway PCB sets: (cursory descripton)
         NOTE: The discrete components, particularly for the shot sound, differ between Taito and Midway audio daughterboards.
         TODO: figure out the difference between the Taito and Midway discrete boards and emulate them both properly. Figure out what the current discrete setup is trying to emulate.
         * All Midway Space Invaders games ([Space Invader Upright], [Space Invader Cocktail], [Deluxe Space Invaders Upright], [Deluxe Space Invaders Cocktail], and [Space Invaders II]) use the same 8080 mainboard, with no emulation-relevant differences between revisions.
         * [Space Invaders II] from Midway (only produced as a cocktail) uses an extra sound board for the simultaneous 2 player head-to-head sounds.
         TODO: remove Space Invader 'invaders' set from mw8080bw.c, it does not belong there at all

      - Taito-USA-made 'trimline' PCBS do not match the taito pcbs either.

MOON LANDER
Manufacturer: Leisure Time Electronics
Year: 1980
Orientation: Vertical B/W
Cabinet: Cocktail


Leisure Time Electronics produced three games: Astro Laser, Moon Lander, and Space Ranger.
The games were designed to be interchangeable with a universal cocktail cabinet which they designed and named "Star Series". The cocktail cabinets share the same artwork with all three games and has a different instruction card for each game.
There were no upright or cabaret cabinets. The game ROMs operate on Taito pc boards.

Moon Lander is a clone/ripoff of Lunar Rescue/Destination Earth. I do not have a manual or schematics for this pcb although
I was able to confirm 5 out of 8 dipswitch settings. I was surprised to hear the sounds effects are almost exactly like when Lunar Rescue used the "invaders" external samples in MAME. The pcb does not play the invader "hit" sound for some reason.
I couldn't find anything obviously wrong in the sound section so it must be that it's just not hooked up as-is from the factory. There does not appear to be a sound-in-attract option.

/*
Cosmo
TDS & Mints, 1979/80?

Notes:
This game runs on modified "original" Taito (3 board) Space Invaders hardware.
There are approx. 70 (or more) wires tied to various parts of the boards, plus
there is an extra board on top of the sound board with a *HUGE* amount of wires
running to it from the main boards. There are 2 EPROMs on the top board that appear
to be for use with colour generation or extra sounds(?) The PROMs on the middle board
have been removed and in their place are a pile of wires that join to the top board.
The remainder of the hardware is just standard Taito Space Invaders..... including
a SN76477 and the discrete components for sound generation.
Note that the sounds and gameplay of Cosmo are VERY different from Space Invaders.
