Well, I don't know about that.  It certainly is possible, but from the outside
of this box, the RF noise is at least 10 times lower than my A500.  I can
actually watch TV, which is a lot more than I could do with my A500 on...

If you need to shield from the other slot, why not shield the slot, not
your board?  Hasn't this occurred to any of those "representative?"

If this info was from the same "reps," they should be shot....  
The things which have bombed for me are things that would bomb on *any*
68030 platform.  This last piece is so mis-informative, that it puts your
other concerns in grave doubt.  See Peter Cherna's post as well...
