Torsten,

I recall hearing that the Read Track command on the CoCo does not work
reliably;  I wonder if that was your experience.  I heard this in
connection with the Spit 'N Image utility for duplicating a copy-protected
CoCo disk;  according to one of the authors, I heard second-hand, the
program had to do several Read Tracks on the same track and kind of
average them to get a reliable track image.
