Hello... I recently dug out my old macintosh powerbook 145b and tried to get it going for college. all i use is simple text and the occasional tetris. Upon booting up i found that the last time i messed with it i had put in a password i guess to protect my high scores. I do not have an operating disk, and i was wondering if there is any special keystroke i could put in that would bypass the password to where i could go in and change or disable it. I do not know what operating system it has. im sure its lower than operating system version 3 something im really not sure but i was wondering if there was a universal remedy for this.
