Copying an Apple II disk?

[billknopp]

Glad you got it working. You can always look at the flux graphically like I showed you via email.

The issue could be with your drive's alignment or the disk (if not an original produced by a duplication machine) could have been produced on a drive that was out of alignment.

I was thinking it could be alignment.  Don't suppose you know where a guy could get his hands on an analog alignment disk?  As I mentioned in my e-mail, I have a bunch of computers that need attention, and even more drives.  I could dust of the old 'scope and do alignments on them while I clean them up.  I got rid of my AAD about 20 years ago, and it would probably be no good any more anyway.  Accurate still has a web site, but I doubt that they are still shipping these.  Anyway, if anyone knows where I could get my hands on a good condition AAD, I would greatly appreciate it!
