I had a hell of a time, and only partial success when
a client's Apple ][+
would not boot. So, they tried their backup copies. Then they tried
EVERY disk they could find. Unlike the SA400 (used by TRS80, etc.), the
SA390 with Apple's own logic board could write to a write-protected disk
when the controller malfunctioned.
Yes, thats' right. I zapped a drive (actually a couple) once by getting the
pin alignment wrong.

By the time I realised what what going on, I'd gone through a lot of my
write-protected disks! Thank goodness for ADTPro!
