Notes:
-----
- Space Invaders Deluxe still says Space Invaders Part II,
because according to KLOV, Midway was only allowed to make minor
modifications of the Taito code.
- 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;

* Two pcbs in a stack, with the function of two of the three pcb stack
pcbs combined.

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
such that the middle PCB (of 3 PCB stack) or the bottom PCB (of 2 PCB

* 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
* 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.

* 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.

with the 3 layer PVN pcb set.

* Bottom pcb combines the function of the Middle and Bottom pcbs
- 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 probably the second-oldest pcb set and may have been made to
allow closer physical interchangeability with Midway's m8080bw hardware,
which had a similar board shape?
* 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.

II" cocktail with electronic color overlay.

SV01, SV02, SV03, SV04, SV05, SV06 - undumped (rev 1), If this exists at all this would be the very first japan release of space invaders (Andy W may call this 'SV0'?)

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)

* 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.

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.

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.
