Things were really interesting in 1979 when the Apple Language System was
released. Apple Pascal used 16-sector disks and thus needed the new PROMs.
However, the newest version of DOS was 3.2, still 13 sectors! Thus, the
BASICS disk dual-boot procedure for Language System owners.

Finally, (mostly) everyone converted to 16-sectors with DOS 3.3 in 1980.
This also made it easier to transfer data between Pascal and DOS.
