Please do an experiment yourself. Fire up a Commodore 610, do not connect any drive to it, and try to open a file on disk #9 - see when error messages you get and when. Then connect a drive #8, and again try t open a file on disk #9 - see the difference. Regards, Michau. Message was sent through the cbm-hackers mailing listReceived on 2014-11-09 10:00:02
