yep, I saw the screws for the main board 🙂 but…

~ also, can we clarify which direction the power goes and from which socket?
Your first post text says:

I have an M-Audio MIDI sport 2×2 MIDIMAN feeding MIDI into an H9. User “Camn” seemed to want something like that too. Please correct me if I am barking up the wrong tree, but MIDI controllers (that need power) tend to feed into an H9 therefore the power should come out of the MIDI Input socket, rather than the MIDI Ouput, no?
