    Re-capped SE/30 still with bad video

    Great! Thanks... I love having schematics for my machines. I've freshened the solder on the VRAM (the two chips near the SIMM banks, labeled 41264). Then I've been checking continuity according to the schematics (especially SE30_P5.GIF) for UE6, UE7, UG6, UG7, UE8, and UF8. So far...
