I'm using 10 hole hard sectored on my N*???
Apple II's used soft sectored format that was not one of the standard.
It used some type of run length encoding or in terms, a data scrambler.
There is no way that with or without software that I'd think you could
read it on a H17 controller, without significant hardware modifications.
