Now we just need a FS table. Thanks FD!

I emailed FD a 3 screen version of this UVP earlier this morning.

Hey guys,
I'm not sure if I'm at the right place, but I give it a try here I'm working on an emulation of Earthshaker pinball, and I just cant figure it out how the ROM controlls the 6(?) lightbulbs that are NOT part of the backbox GI solenoid. These are seems to be flashing in a repeating pattern until some of the playfield flashers start flashing, so possibly these flashers can control them as well. But how the idle pattern is working? What controls it? I can't find any signal from the ROM only the ones for the playfield inserts and the normal solenoids... Huge thanks to anyone who could help!

All system 11 blinking bulbs are controlled by the lampmatrix.

Flashers are controlled by solenoiddriver (AC-select, c-bank).

 

G.I is either on or off.

 

Wich lamps are you referring to?

The "jackpot value" lamps are controlled by the lampmatrix (column 8).

 

Maybe your machine has some bimetal-bulbs in the GI-string?

Thanks for your reply biomii! 
I marked the bulbs in question on this image:

I hope this clarifies it.

Sadly the IRL machine is not in reach for me anymore (I only borrowed it) so I could get info of these from youtube only

They look like flashers in this picture:

So, those are controlled by the solenoiddriver.

 

However, this post says earthshaker had factory-installed bimetal bulbs:

There are 200 prototypes (with collapsing institute building), maybe they have different backbox lighting as well.

 

The manual might help you out:

Yeah, I know some of the flashers within the playfield can flash together with these. Thats okay, I can figure that out. But if you look at the beginning of this video, these 6 bulbs (behind the helicopter, the !, etc.) are blinking even in attract mode, and during gameplay as well, when nothing interesting is happening at the moment. So they are doing this blinking "idle".
 

 

And this is what I need to know, how this pattern blinking is working...

Those are definitely bimetallic bulbs; they blink randomly without being controlled.

 

Works like this: inside the bulb is a little piece of 2 layers of different metal that is straight when cold, but bends when heated up.

It's acts as a conductor to power the wire in the bulb, so it lights up.

When the bulb is lit it generates heat, which makes the bimetal bend and disconnects the powerflow so the light goes off.

Then it cools down, the bimetal becomes straight again en makes the power connection again.

This cycle makes the bulb auto flash every second or so.

 

In the video he says it is the sample (prototype) version, so I believe the first 200 used bimetallic bulb, later models had flashers.

OMG mind blown... Thanks for this, really appreciate it!
