Introduction
Keyboard 17
Note
The user must hold down a key combination for at least 1 second to
allow the ADB microcontroller enough time to respond to the NMI
or hard-reset signal. ◆
Note
The NMI in the Macintosh LC 520 computer can always be activated
from the keyboard. This is a change from the Macintosh LC computer,
where the keyboard NMI function can be deactivated by the software. ◆
