OOOoooh, that's makes sense.  Thanks.

So the volume number is somewhat overloaded to indicate "disk change."
It seems to confirm, too, that there is only one volume number
for a floppy.  Does that also explain why track 0 has volume
number of zero?

Do you know if CP/M drivers for the Heathkit hard-sectored controller
do the same thing?
