can DOS 3.3 sector be larger than 256 bytes?

[Robert Jensen <jensen@aplcomm.jhuapl.edu>]

There are two bytes in the DOS 3.3 volume table of contents that
hold the number of bytes per sector.  Does DOS 3.3 use this value
for anything, or does it just assume 256 bytes per sector?  Is that
part of the VTOC just there for compatibility with some never
realized upgrade?

I created a DOS partition on a SCSI disk and I would use 512 byte
sectors if this is possible.  I could create a larger DOS disk that
way.  I patched into the RWTS routine and everything works just
fine, but I am only using 256 bytes of every SCSI block. (I have
a II+ and still use a Merlin assembler that predates ProDOS.)
