I think the truth is that nobody has bothered to write a device driver for
the ProFile under DOS 3.3.  I mean, the ProFile is a block device as far
as ProDOS is concerned, but based on what little I know of 3.3 internals,
there is no reason that DOS 3.3 couldn't be hacked to handle the ProFile.

One problem you might run into, though, is if the programs in question
access the disk directly rather than going through RWTS.  As long as the
program uses the DOS disk management routines, it shouldn't be any worse
than running 3.3 on an 800k drive...which is something else that Apple
claims cannot be done, but I have here a copy of Amdos 3.3 that works just
fine... 8-)
