[Coco] Program to copy disks track by track

[Diego Barizo]

A couple of years ago I used a PC DOS program called HDCopy to make 
backup copies of my OS-9 and Deskmate CoCo floppies.
Since it works on a "raw style", not caring about formats or OSs, I 
believe it might be able to backup even copy-protected disks.
If anybody wants to try it, I can email it. It's a very small (46 Kb) 
program.
