AFAIK, DOS 3.1 was the first publicly available version.

Since Woz wrote RWTS in the process of developing the Disk ][ drive and
controller, it's safe to say that RWTS preceded any DOS version.

The very first RWTS may have been 4+4 coding, but Woz quickly progressed
to 5+3, then later to 6+2.  The final iteration was the ProDOS-style
RWTS that decodes nibbles to data on the fly.
