    Much information about Space Invaders PCBs and other Taito and Midway
    sets and hardware contributed by Andrew Welburn


    Notes:
    -----

    - Midway Deluxe Space Invaders still displays 'Space Invaders Part II',
      because of the terms of the licensing agreement.
    - DIP settings/locations verified from manual for:
      sitv, sicv, invadpt2, lrescue, invasion, invrvnge

    - The Taito Space Invaders hardware comes on at least five board types;
      The Taito manufactured ones are:
      * The "L-shaped" PCB set, B&W and Upright mode only
      * Three PCBs in a stack, often called the '3 layer PCB set' (most common)
      * Two PCBs in a stack, with the function of the CPU/ROM boards 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 any hardware of any sort for electronic color screen
            overlay or screen flipping for cocktail use.
        * 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 analogue audio and sn76477, and volume pots
            - 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 DRAMS 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 the earliest 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 connection to the PSU, and B&W composite output "T" connector
        * 2 layer PCB set details:
          * This PCB set came in one version for PVN use, sharing the same top PCB
            as 3 found in regular layer PCB sets
          * 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:
          * TVNxxxxx (3 layer PCBset) - B&W only, used on "T.T Space Invaders"
            cocktail with 'blended' single-sheet gel color overlay.
      ***TODO: this overlay is not supported yet!
            Several revisions (at least 5 ROM, 3 cpu, 3 audio) of each PCB exist
            for this set.
            Does support flipscreen.
            Does not have the color overlay circuitry nor places for it on the PCBs.
            (Later TVNxxxxx are actually rebadged CVNxxxxx, see below)
            Came from factory with one of the SV or TV romsets.
            Capable of running TV, SV or CV romsets.
            This PCB set is probably the oldest one and was designed at Taito.
          * SVNxxxxx? (L-shaped PCBset) - B&W only, used on "Space Invaders" Upright
            with 3-separate-sheets-of-gel 'strips' color overlay.
      ***TODO: this overlay might not be supported properly yet!
            Does not support flipscreen, was intended for upright cabinets only.
            Audio PCB daughterboard has part number SVN00001 or SVN00003.
            Came from factory with one of the 6x 0x400 or 4x 0x800 romsets
            Capable of running TV, SV or CV romsets.
            This is the second-oldest PCB set and does not share physical compatibility
            with Midway (interboard connector is of a differing pitch)
          * CVNxxxxx (3 layer PCBset) - Color, used on "T.T Space Invaders Color"
            cocktail with electronic color overlay.
            Does support flipscreen.
            Note that later TVNxxxxx PCBsets are actually 'rebadged' CVNxxxxx
            PCBsets with the color overlay circuitry unpopulated, and can be
            'upgraded' to CVNxxxxx by adding a few components and proms.
            Came from factory with one of the CV romsets.
            Capable of running TV, SV or CV romsets.
          * PVNxxxxx (2&3 layer PCBsets) - Color, used on "T.T Space Invaders Part
            II" cocktail with electronic color 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 all romsets.

       * The following Romsets are known, ROUGHLY from oldest to newest:
         SV01, SV02, SV03, SV04, SV05, SV06 - undumped, this has never been seen in the wild and may never have existed.
         SV01, SV02, SV10, SV04, SV09, SV06 - sisv2 (rev 2) (Andy W calls this 'SV1', and the midway 'invaders' set is based on this romset)
         SV0H, SV02, SV10, SV04, SV09, SV06 - sisv3 (rev 3) (Andy W calls this 'SV2')
         SV0H, SV11, SV12, SV04, SV13, SV14 - sisv (rev 4, 5-digit scoring) (Andy W calls this 'SV3') (this set is likely newer than the TV0x sets)
         TV01, TV02, TV03, TV04 - sitv1 (rev 1)
         TV0H, TV02, TV03, TV04 - sitv (rev 2 with bug fixes)
         CV03, CV04, CV05, CV06 w/proms - undumped (but may be the same as one of the sisv sets 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 - invadpt2a - (same as PVxx set just split differently)
         PV01, PV02, PV03, PV04, PV05 w/proms - invadpt2
         Note: SV0H and TV0H are called in Taito documentation "SV01-1" and "TV01-1" most likely due to someone along the line mistaking the '1-1' for an H or vice versa when writing the documentation or creating the labels.

    - Midway PCB sets: (cursory description)
      * 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 m8080bw 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.

    - Taito-USA-made 'trimline' PCBS do not match the Taito Japan-made PCBs either.


    To Do:
    -----

    - Midway PCB sets
      * The discrete components, particularly for the shot sound, differ
        between Taito and Midway audio daughterboards.
        + 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.
      * Remove Space Invaders 'invaders' set from mw8080bw.cpp, it does not belong
        there at all

    - Space Chaser (schaser)
      1. Schematic has SX2 & 4 swapped by mistake.

      2. Dipswitch 4 we have listed as "Easy/Hard", however the manual says
         it should not be used. The Hard position displays many bugs.

      3. Confirmation of these on a real machine (schaserb set) have been
         received from the owner of the PCB.
        "Hi Rob,
         I seem to get the same bugs as you with Dip4 set to off.  Score starts at 9000,
         2 missiles on first level etc..  It makes no mention of dip4 adjusting the hardness
         in the manual, are you guys sure that's what it was intended for "in the factory"?
         However you were correct in thinking the schematics were wrong.  My multimeter found
         the following:
         15k resistor - pin 7
         39k - pin 10
         82k - pin 12
         It looks like they have Sx2 and Sx4 the wrong way round on a latter page of the schematics."
           Thanks to Andy Raven for getting this information.

      4. The "Hard" mode bug can be fixed with a single byte patch: ROM_FILL( 0x47e5, 1, 0xc3)

      5. I have seen real machines with Hard mode set, that worked properly, thus there
         must be yet another romset still waiting to be found.

      6. Strange bug; sometimes the missile sound continues into and past the
         music/explosion. This didn't happen on the real machines I played.

    - Space Chaser (schasercv)
         These cheats exist in this game:
         1. Hold down 2P DOWN (the F key) while it says INSERT COIN. Then
            insert a coin and play. You will have 2 extra ships.
         2. In the Hard difficulty setting, you normally start at level 4.
            Hold down the 1P START (the 1 key) while it says INSERT COIN.
            Then insert a coin and play. You will start at level 5.

    - Crash Road (crashrd)
        * Seems slightly buggy. On the odd occasion it can freeze followed by watchdog reset.
        * The "hard" level has the same bugs as noted for schaser. It should not be used.
        * The cocktail mode doesn't work correctly and also should not be used. The directional
          controls are not scanned during play. The flipscreen signal occurs once at the start
          of player 2's level, then turns off.
        * The enemy never goes faster in the inner loop, so the game is much easier to play.
          It also means that the missing yellow band is never needed.
        * The "effect" sound (the continuous clunking noise) doesn't seem to be supported, but
          we'd need a schematic or real machine to find out for sure.

    - Space War (Sanritsu)
      * I seem to recall that the flashing ufo had its own sample
        sound, a sort of rattling noise. Unable to find evidence
        of this (so far).

    - Steel Worker, Space Combat
        Holding down the coin button causes the credits to rapidly increase.

Taito Galactica / Space Missile

This game was officially only distributed in Brazil.
Regarding release data, not much information is available online.

ROM dump came from a collection of old 5 1/4 disks (Apple II) that used to be in the
 possession of an arcade operator in the early 80s.

TODO:
- correct sound (currently same as invaders)
  * sound mutes when a few aliens are left?
  * port 7 write is used too, looks like it's for music similar to indianbt
  Note that bass background hum and sound effects are already basically correct.

    This game was never released by Model Racing to the public.

    The assembler source files for this game were extracted from the original floppy disks used by the former Model Racing developer
    Adolfo Melilli (adolfo@melilli.com).
    Those disks were retrieved by Alessandro Bolgia (xadhoom76@gmail.com) and Lorenzo Fongaro (lorenzo.fongaro@virgilio.it) and
    dumped by Piero Andreini (pieroandreini@gmail.com) using KryoFlux hardware and software.
    Subsequently Jean Paul Piccato (j2pguard-spam@yahoo.com) mounted the images and compiled the source files, managed to set up a
    romset and wrote a MAME driver that aims to reproduce in the most faithful way the work of Melilli at Model Racing in late '70s.

    The game driver is not based on hardware inspection and is solely derived from assumptions I've made looking at the assembler
    code and comments written into the source files of the game. Several of those hypotheses came following the directions of
    previous yet contemporary Model Racing works (Eg: Claybuster) and were confirmed by Melilli himself.

    Being unreleased this game lacks an official name, thus the name used in the source files was used instead.

TOS sound
D0-D7 is pushed into a LS273 (Octal D-type Flip-Flop) and its value is used to preload the starting value of
two, cascaded, LS161 (Synchronous 4-Bit Counters).
The counters drive a J-K Flip-Flop generating a square wave signal driven in frequency by the preloaded value.

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.

Space Invaders (Electromar, Madrid) 1980

Board by Roselson
Dumped by Ricky2001 from Aumap

This game runs in a clone of a Midway L-Shape Space Invaders PCB with different connectors, but identical.
The board is updated with a litthe daughter board for the reset, instead of being generated in the Power supply.
Most of the Texts are in Spanish but keeps the original name "Space Invaders", also in the psb is writen a Patent number, I think this means it was a licensed version.
