[Coco] OS9 floppy descriptor

[Chester A. Patterson]

I'm wracking my brain trying to remember how to modify a /D0_40D.dd or
/D0_35S.dd to make a D0_80D.dd But my memory doesn't help me. I'm fed up
with buggy floppies and going to move everything to 3.5"
I've got OS9v2, ezgen 1.06, and some other tools, on the occasions when my
current D0_40D doesn't give me read or CRC or any number of other errors.
Help!

Thanks.
