Alternative 2: If your Classic boots from sd3:a, get a disk with
SunOS4 at that location with known root password and boot the Classic
to multiuser. Log in as root and strings - /dev/eeprom and do a bit of
guessing. If you only can get SunOS5 you can do the same thing but you
are limited to the eeprom command.
