[Coco] DECB and BACKUP

[Ron]

Hi Art,

I do have your ADOS-3 (from many years ago) burned on some EPROMS, so I 
can certainly use those.  If I just use wildcard copy, that's only good 
for DECB disks, correct?  I would still need address any OS9 disks as I 
would not be doing sector by sector copies any longer, correct?

I dread trying to do something with DSKI$ and DSK0$...

Thanks for giving me another possible option, though!

-Ron
