This did indeed prevent me from getting into the control panel, but it also made my machine pretty much go bonkers. Had to reboot. On ROM 3 it just printed Apple IIgs at the top of the screen as expected, without preventing control panel access or messing up anything else. (Obviously, this is not a supported way to prevent control panel access.) -- --Dave Lyons, Apple Computer, Inc. | DAL Systems AppleLink--Apple Edition: DAVE.LYONS | P.O.
