Im desperate because later today Im being interviewed about my mac and tech in general, and i really need my notes and stuff on the mac, plus it would be so embarrassing that iv'e set a password i cant remember - might as well cancel the interview I have tried to remove the 1gig ram block, that should reset the password in the old Open Firmware macs but no dice!
