(This book is available from APDA at 1-800-282-APDA; I believe you can get it without being an APDA member.) You need to "unlock" the accelerator and then set it to slow mode. I believe code was also published in a Q&A column, but I don't know what magazine. -- David A. Lyons, Apple Computer, Inc. | DAL Systems Apple II System Software Engineer | P.O.
