  Actually, it can run any version of DOS (3.2 or
3.3) but for 3.2 you need
 the 3.2 controller.   
  Um, Sellam, are you sure you've not got 3.2/3.3 compatibility round the
  wrong way?  The P5A and P6A PROMs that came on Disk ][ cards sold with DOS
  3.3 (16-sector) can also handle the encoding used for DOS 3.2 (13-sector),
  but P5 and P6 PROMs supplied with Disk ][ cards can't handle the encoding
  used by DOS 3.3.  There are a very few exceptions related to copy protected
  disks, of course, which is why some of us had switchable cards.

I've got several disks from apple called BASICS that will allow a dos3.3 
system to boot up and manipulate dos 3.2 disks. The only dos3.2 disk I've 
ever seen was/is a diagnostic disk from call-APPLE that i got in a box of 
materials i got from someone. Prodos can be used with any apple ][ with 64k 
and an autostart rom. There is a bug in version 1.1.1 that can trash track 0 
but I've never had it happen. Later versions do not have this problem. I 
think it's prodos version 1.8 (or is it 2.0) that won't run on a ][+ anymore.
