I'm trying to help Richard out with copies of my ISIS-II diskettes. The
SD diskettes read just fine using imagedisk, but the DD ones use M2FM
(aka MMFM) encoding and are not recognized.
In researching this on the net, I'm seeing conflicting claims as to
whether the Catweasel controller will make sense of this format. Does
anyone know from personal experience that it will? If so, what software
tools were required?
TIA,
Steve
Hi Steve
Catwheasel should be able to read the bits. I have the spec
on the different special marks some place. I'm not sure
how it would be written back though. It can't be created
with any of todays controllers.
I'll keep an eye out for the clock/data spec but it may take
me some time to find it.
