I own a vintage "LC II" (a.k.a. "Macintosh Performa 400") with System 7.x installed years ago. Unfortunately I'm not able to log in anymore, because after the initial boot the screensaver fires up and locks the screen with a password.
I would like to know either if:
there are any key combinations or such to "unlock" screensaver/log in?
there are any key combinations to "reset things"?
there is a easy–to–follow guide to create installation floppies to re-install from scratch?
