And I told him to use the sector editor in Copy II Plus to fix the startup
program!  C'est la vie...

As for the DOS 3.3 System Master, MUFFIN is the program that converts files
from the 13-sector format used by DOS 3.2 (and earlier versions of Apple DOS)
to the 16-sector format used by DOS 3.3.  Earlier versions of Copy II Plus (I
think before 6.0) would also do this conversion, as well as make 13-sector
5.25" disks.  I did this once or twice just to play around, but it was never
usable because I didn't have DOS 3.2 to boot into.  It would also have been
impractical because I would have had to boot DOS 3.3 and run START13 to boot
a DOS 3.2 disk.  (The disk controller in 99% of Apple 5.25" drives in 
existence is a 16-sector controller, though I did see a 13-sector controller
(C) 1978 in a used-computer-parts store a few weeks ago.)  Finally, there's
the simple matter that you lose about 19% of your disk capacity.  DOS 3.3 was
a significant advance in Apple DOS; ProDOS, of course, uses 16-sector disks
because most drive systems out in 1983 were, of course, 16-sector drives.

That's your history lesson for today.  Class is dismissed.  :-)
