Talk:Twilight Zone Eddy Boards

Referring page calls the switch output an opto - some clarification is needed as what is meant by that, as it's an eddy sensor and there aren't any optos involved via the opto driver boards? (Or does the output from the eddy sensor then go to the opto driver board too?)

I updated the reference to "optocoupler". We probably need a pinball semis page that describes all of these things. --Mr 16:15, 27 April 2011 (BST)
