Apple IIe (Enhanced): Distorted Double High-Res Graphics



PROBLEM DESCRIPTION: While trying to run a program that uses
Double High Resolution Graphics (ie. DazzleDraw, MouseCalc, etc.), screen
output appears poor, unreadable or badly distorted.

CAUSE: The Molex Jumper might have fallen off, or been removed
from the the Extended 80 Coloumn Card.

CURE: Reinstall the Molex Connector as explained in the Extended 80
Column Card Manual.

Note: Later versions of the Extended 80 Column Card do not have the jumper
connected by the molex plug described here. That connection is already made on
the card at the factory.
