Once upon a time, Apple has announced their disk drive, compatible with 13-sec disks then, really sooner than excepted, Apple has decided to switch to 16-sec disks.

Software publishers where going into a dead end: shall our software be for all (16 and 13-sec people) or limited to to 13-sec people (Washington Apple II people, raise your hands)

Well, there *is* BOOT13 and BASICS (plus Franklin's ripoff of BOOT13, and my hacks of both).

As far as this is concerned, this is just a matter of track 0 formatting. In 99% of the cases, a max of 10 sectors is/are concerned, therefore one can add a 13-sec boot1 sector when the standard is 16-sec.

I figure it's just how you arrange DOS on the disk, to put room on track 0 for two sector 0s.
