[rescue] SGI 320's

[Andrew Weiss]

Speaking of which... oh the irony.  I just had a service call for one 
of these today.  The LCD panel video daughterboard is probably the 
issue.  The thing has horizontal travelling defects (multicolored 
vertical stripes that look like a set of NMR data before a Fourier 
Transform [vertical scribbles very close together <no gaps> of varying 
length] that show up more on black backgrounds and such).  They travel 
like a TV with bad vertical hold settings.  The VGA signal is good.  
Anyone have any ideas.  My first inclination is the daughterboard, but 
then I was trying to figure out what would contaminate a digital signal 
in that fashion.
