Barring the fact I just noticed this BLUE PCB was running my system 9 williams space shuttle (vs every other component that has a 535 williams sticker on it)...

Is the ID for this board 100887? or 5336? How are Data East PS numbered?
Why is it blue? I can't find anything in google images that has a blue PCB?
Any thoughts on year this was produced?

Apparently it runs my SS fine.
Thought the first thing I did, when I got the pin 3 months ago was replace the entire CN8 plug as it was a bit melty and scorched (you can see the aftermath on the the relay above).
So... is this normal: Replace a system 9 PS with a Blue Data East PS?
Blue???

Thanks for the info! That helps focus my searches. Was just reading up on how to "bullet proof" my Williams Board (aka Vid). Seems like a moot point now given I have a DE PS (which in of itself appears to be hacked). Do you have an easy link to DE PS schematics/specs?

Tx.
Amusing thing was that I had been staring at the Williams circuit diagram and referencing connections, etc. on the [Date East] PS board, without realizing it wasn't a Williams board. First time pinball owner (3 months now)... picking up on all the "obvious" details bit by bit.
