Beneath Apple DOS (pg 4-2) states that the first byte of the VTOC is
not used.
Their sample VTOC dump has a $04 in the first byte. My *guess* is that
it may indicate what version of the VTOC structure is being used.

Beneath Apple DOS (pg 6-5) states that the first byte of the IOB is a
Table Type and must be $01. Again, I think this indicates what version
of the structure is being used.
You can find Beneath Apple DOS here:
