Since the Q60 has no separate loader like the Q68, SMSQ/E has to execute from EPROM at first, to do the copying. If the EPROM has a timing problem on the borderline, it is possible that only very little data is corrupted during the copying process from ROM to RAM. Which could result in something that is not an immediate crash. (I'm not saying it is a timing problem.) _______________________________________________ QL-Users Mailing List
