We were just speaking about the *hardware* interleave. The normal 154x
and 157x formatting routines always incremented the sector numbers. The
interleave was just a software thing on top of this.

There might be fast formatters that did it differently. However, as long
as this is not a copy protection thing, this should not do any harm,
either.

I only remember one PC tool (was it d64edit? I am not sure, but it was
handled on this mailing list here) that always created D64 with an
interleave of 1. For emulators, this was not bad, but it was very bad
for the real thing. It took some time to convince the author of that
tool that his choice might be... well... sub-optimal. ;)

Regards,
Spiro.
