Lua is a form of programming language developed around 1993.
It ran a function of trying to "initialize" a programmed index that isn't working.
In other words, something got corrupted.
There a could be a bad battery that couldn't hold the index list in the programming, possibly something failing on the MPU.
Could be a million things that caused this corruption, a bad chip, a bad IC component, a bad memory stick, etc etc.

On the bottom of that screen, you are instructed to turn the attendant key... try it.
When you do that, does it revert back to this red screen?
If so, then you have a fatal fault, which requires the need to clear the machine and re-install the game.
Chances are though, it may at some point, come back.

Use winimage to copy the cfast card and then write it back to a CF card.

Yes, lighting cash games play, expensive

Does anyone know what this error is about?

100% agree Tilt! Chris has always been patient and helpful for me! Just didnt know if there were different types of buttons as they look different but all work well which is the main thing

Hi,
I'm new to slot machines.  I'm having problems with the touchscreen in the area where the denomination is changed.  I push on $5 and it takes it like the $10 was pushed.  I am finding that its acting as if its 1 space off to the right. 
If I hit the area to the right of the $10, I'll get the $10 selection.  Acting as if the touchscreen needs to be calibrated. Do I need the software for that?  And where might I find a service manual for this unit? Its  a IGT S3000 pinball slot.

Thanks,

Bob
