[comp.sys.apollo] Vertical stripes on DN10k

rtp1@quads.uchicago.edu (raymond thomas pierrehumbert) (05/16/91)

I have a DN10k with the "cheap" 8-bit 19" color graphics subsystem.
I just rebooted the machine (because of an unkillable hung
NFSD process that was locking out the network!)  after 
a proper shutdown, and now the display comes up with vertical
black bars, rather like looking at the screen through prison
bars.

I rebooted again, and the display looks the same.  Totally
unusable now.  Sound familiar?  Any fix?
