The mini-assembler had to be moved away from $F666, since that space is now
pretty much irrevocably claimed by Applesoft.  I believe it now resides
somewhere in the $C800 space, along with the 80-column firmware.

Fortunately, though, you don't need to know its address anymore.  Just type
an exclamation point (!) at the * prompt and press RETURN.

DOS 3.3 itself works just fine on the enhanced ROMs.  There may be a few
programs that fail, though, because they use undocumented ROM entry points
that were changed in the enhanced ROMs.

I'll let somebody else tackle these.  (I'm typing this in my office at
school, and all my Apple II info is at home.)
