Two versions of 2.11 I know of supported 720k disks,
one the
DSQD 5-1/4" format while the other is the DSDD 3-1/2" format. (both
Tandy specific). Two other versions I have mention nothing in the
manuals over 360k (Zenith and Corona, though the Corona does mention
160k as well). I was thinking that maybe it would only be formatting
it as 720k and it might not error out if the drive is a true 720k
drive. The high-density drive would of course complain when he tried
to read it though.

I had a Kaypro 2000 running 2.11 on a 720k drive. I've successfully read
data disks from that system on my PowerMac G4/450 with a 1.44MB USB Floppy
drive.
