<p>Under the vertical Toolbar, are 2 LEDs, one for each floppy disk drive. The colors indicate drive status:
<li>Black: drive is off
<li>Green: drive is reading
<li>Red: drive is writing
<li>Orange: drive is reading (and floppy is write-protected)

<p>By default the Disk II Controller card has the 16-sector firmware (as used by DOS 3.3 and ProDOS). But if a WOZ image that internally identifies as 13-sector format (eg. DOS 3.2) is put into drive 1, then from the start-up/logo screen (or the next reset), the Disk II Controller card's firmware will automatically be switched to the old 13-sector firmware, allowing the disk to boot. And it will automatically switch back if a non-13-sector WOZ (or any non-WOZ) image is put into drive 1 and the machine is reset.<br>
NB. There is no support for this feature for non-WOZ images.
