SYMPTOM Patterning occurs after IC801 has been changed.
CAUSE
In later versions of this chassis a slightly different VDP was fitted. The type number
(VDP3120) is the same, but the revision number is different.
ACTION
If patterning is experienced after changing IC801 (VDP3120 only), remove C824 if
fitted. This capacitor is connected from pin 33 of IC801 to ground.
