LANE@SUMEX-AIM.ARPA (11/23/83)
From: Christopher Lane <LANE@SUMEX-AIM.ARPA> The Commodore 1541 (and 1540) 5 1/4 drive does not use the hole in the floppy for anything, there is a place in the drive for a sensor, but it's empty. So to use the other side of a SS floppy, you need only make the write protect notch. However, some people do warn about the effects of spinning the disk the wrong way .... - cdl -------
