U13B and U17B Differential Amplifiers

[scottieb]

Hi Rob,

Whats the purpose of the U13B and U17B differential amplifiers? the inputs do not seem to be connected to anything, is it possible to use these as analogue inputs?

Regards,

Scott

I have absolutely no idea!
Detailed hardware questions are a little bit out of the scope of the forum, this sort of question is best directed to the Wiki I'm afraid.
I know that there are 'hidden' extra inputs, but the exact details are unknown to me.
