When you say fresh disks, did you mount two internal
hard disks inside the SE/30? You're probably going to need to replace a couple
of
capacitors on the analog board. There's one particular
capacitor that comes to mind as causing a different
problem, it's nonpolar, so watch out. Is it like a
60hz kind of a wave in the picture, or is it more
random? A wave through the screen, like a waving flag?
It happens perhaps once every ten seconds. The disturbance is something
like a ripple or wave that crawls up the side of the screen.
