[sdiy] Standard markings for modular I/O & CV versus Audio?

Brian, Befaco were kind enough to send me a free set of bananuts and a
tool, but I don't know what it's called. I prefer Roman Sowa's tool as it
has a guide in the middle, the Befaco ones are kind of hard to keep in
place as you turn. But alas, Roman's is the wrong size for the bananuts
(hint hint Roman!)

John, I agree that color should not be the only indication, but if
understand correctly these panels have already been made, so changing the
graphics may not be an option.  If its the standard seems to be the
inverting thing you mentioned. Greyscale, Sonic Potions, North Coast, Moog
and Joranalogue are some examples I see in my system where the writing gets
inverted for outputs, sometimes with even the jack surrounding square
included in the color swap.
