The VS3100 in 38-344 named william-gibson is having video problems.
From past experience the VRAM seems to have gone bad.  The symptoms
are: it will work fine for a while, then the screen is completely
scrambled.  The video signal seems to be ok, it seems that the bits
are scrabled in the VRAM.  Also from previous experience, it will
probably take a new system board to fix it.
