Does anyone know what this board is from?. Why does it exist?

Dunno what it's from, but I do know what it is.

It's a simple "Filter" board off a vid system.
It connects between the main CPU board, and the game's wiring harness.
It filters all of the signal lines (all those little capacitors), as well as the DC power
with a pair of Inductors (coils) and more capacitors.

It's not really required, and was likely an add-on board for certain markets (coutries) that required a better suppression of EMI noise to meet certain codes.

Thank you! I have been most curious as to what it was, and why it was needed.

So no chance in people starting a bidding war on ebay for it eh... Unless I call it an "extra special RARE filtering ..........

Thanks for the info

Hehe .. not much chance of that ...
unless maybe they want to put the game in a hospital or something, to prevent it from messing up the critical medical equipment & stuff.
