AppleWorks: Apple IIe May Lock Up With Extended 80 Column Card

The computer may work fine in other applications but fails with AppleWorks using the extended 80 column card.
CAUSE: The MMU (P/N 344-0010) chip may have failed.

CURE: Replace the MMU or logic board if MMU not available.

If this cure does not resolve the problem, go back to the Word Search screen and search on the product's name and HTS and GTS to obtain a General Troubleshooting procedure.
