there is colour composite out on the 520 mate...
you have no sound going into the 520,no cable connected.
the rf shield is already there,so im not sure what you mean in the video.
as for the floppy,try to take it apart and grease it,there is two switch's and they might need switch cleaner on them.
and its probably full of crap and dust and so needs cleaning.
