Apple ][ (clone) disk booting

This is taking me back many years, and I didn't do much with Apples 
anyway, but IIRC the DOS 3.3 system came with a disk that you booted, 
then replaced with a 13 secotr disk and it booted that. Since the new 
state machine could handle 13 sector disks without problems, and since 
the boot PROM was only used for booting, there was no problem after that, 
the system acted as a 13 sector one). There was also a program, IIRC 
called 'MUFFIN' (why???) on the 16 sector DOS disk that would transfer 
files from 13 sector disks to 16 sector.

It doesn;t :-(. DOS 3.3 will not natively read a 13 sector disk. The 
hardware can do it, the software can't.
