[Coco] A little help with DriveWire

[Boisy Pitre]

That's correct, only if that OS-9 disk is a 35 track, single-sided  
disk.  Otherwise, it won't get backed up fully.

One of the things that would be nice is an M/L program for Disk BASIC  
that would use the DSKCON calls to read 35, 40 and 80 track single  
and double sided disk images.  That would allow those disks to be  
copied easily.

"If there is truth to the proposition that knowing the past helps us  
to understand the present, I believe there is at least as much truth  
to the proposition that what we know of the present is crucial to our  
understanding of the past.  What we have not ourselves experienced or  
observed we can at most only partially and imperfectly comprehend;  
and I suspect that there is much in history that is so remote from  
our own experiences or observations as to be largely beyond our  
understanding." - Kenneth M. Stamp
