Space Invaders Schematics

I'm trying to chase down all available versions of Space Invaders Schematics.
Below is what I have already.
I'm looking for any schematic not shown below or info sheets on troubleshooting, modifications, hacks etc.
Feel free to post here or PM me with a link if you prefer to share it privately.

RAM Fault Troubleshooting

My 2 cents.

In the Taito cocktail 3-boardset the ram order is backwards (1/A) being on the right.

I tried KR565RU1 bulgarian clone rams and works perfect.

There is no parts placement board image for the original space invaders with discrete 74LS151 shifters on the manuals, only with the later IC (also used in Part II).


Thanks!
