LCD woes - test-drb@ccmp.vtda.org

Probably "Hercules Graphics Card" - Hercules made the original
mono graphics card that was cloned a lot and most cards for driving

 Oh, and BTW, I electrocuted myself last night when I touched some exposed
 wiring going to the LCD panel.  It surprised me that there was that much 
Is it backlit?  Fluorescent backlights use relatively high voltage.
