	96 track per inch drives are 80 track devices.  Many of these
	drives will work at 720k or 1.2m.  They get 720k when run at
	300 rpm and the standard 250k bit rate.  They will get 1.2m when
	run at 360 rpm and a 500k bit rate.  The amiga can only handle the
	250k bit rate and would get 880k when run at 300 rpm.  The amiga
	would not hold as much data if run at 360 rpm.

	Try playing around with the mount list to get 80 tracks.

	I have built a 5.25 floppy drive with autoconfig and diskchange.
	The amiga can't tell the difference.  I have been working on an
	article, but haven't found an universal way to do diskchange.
	Any ideas?  If anyone is interested, send me mail.  Enough interested
	may get a usenet post.
