We've always had the same problem with our SE/30, and I remember
seeing at least one other posting about it on this newsgroup.  
The horizontal lines appear approximately half an inch from the
top and bottom of the screen.  Our machine has never been upgraded. 

Do any other SE/30 owners out there have this sort of flickering?  
Even better, did any other SE/30 owners out there figure out how to
fix it?  Please post.
