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,

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.
