Too early in the day... Just checked the sources for the formatter,
and it's 30 256-byte sectors per track not 32.
So clarify this for me. Someone figured that they could squeeze more
out of a track than the IBM System 34 standard? How was this done? By
decreasing decreasing the gap lengths?

That's fairly conservative, but works out to
almost a 1MB for the
DSDD diskettes. Most systems I'm familiar with formatted at 32 x
256 in DD mode.
What?! Using what controller chip? How that's even possible
while
maintaining the same 360rpm?
