Acorn BBC Master 65C102, Руководство пользователя

Страница: 9 / 16

The top line of the display shows that the TUBE and 65C102 co-
processor are now recognised by the machine. If the message on your
machine does not indicate the presence of the 65C102 co-processor
then first use the *STATUS command to determine whether the TUBE is
correctly configured, and assuming that the configuration is correct,
refer to the ealier part of this section to check that the upgrade
has been carried out correctly.
If neither of these courses of action uncover the cause of the
problem, the complete machine should be taken to your nearest Acorn
registered dealer for testing and, if necessary, repair.
