[Coco] Calibrating disk drives

[Bill Pierce]

Art, I gave a new link today which should work. Guillaume has been "repacking" a lot of stuff on TCCA so old links won't work.

If a Dysan test disk is available, the J&M Memory Minder program for
the CoCo will work with it for drive alignment, with nothing else
needed.  There was some  discussion of it here a couple of years back,
at

http://comments.gmane.org/gmane.comp.hardware.tandy.coco/57629

and Bill Pierce gave a link to the program, which unfortunately no
longer seems to be a working link.
