3.14.4. How do I enter Service Mode in the Lisa's ROM?

Turn on your Lisa. During the self-test (but after the first "click"), press the Spacebar. When you reach the "Startup From" menu, select a nonexistent volume (such as the floppy drive). When it gives you the error message, press Apple-S. You should then be in Service Mode.
