Okay, I've got newer drive calibrated verified it with an old version of
Copy II plus drive speed between 198 and 202.  One set of new drive at 200
and the other at 199.  So we're good there.

Now, how do I calibrate the old Disk II drives, do I have to open them up to
calibrate?

Thanks for all the help.
