Come to think of it, I do have a set of disks that may be considered QD.
It's from a DEC Professional 350 computer. DEC RX50 I believe is the model
number. It holds something like a meg or something like that. That may be
a QD disk because I know they don't work very well in some drives, like
the 1541 for example.
