Catweasel NorthStar / Catweasel Heath?

I am still working on Catweasel NorthStar project and making good progress.
The program can now make images of SSSD, SSDD, DSDD, and those troublesome
"mixed density" disks. There are still a few minor bugs to resolve and
another round of testing to go through. However, I am planning on soon
releasing the code for an initial round of testing.
Since the CWNS program is only going to appeal to a very limited audience,
the first rounds of code release and testing will be done on the
NorthStar_Computers Yahoo Group. If you would like to participate, please
join us at:
I believe the CWNS program is finally coming together and I am considering
the next project. The Heath H89 computer using H-17 disk controller uses
the same media as the NorthStar (10 sector 5.25" hard sector floppy disks)
and in some superficial ways are similar to the NorthStar SSSD disk so this
seems like a logical next choice. I would like to extend the concept of
CWNS to include Heath hard sector disks (i.e. Catweasel Heath, CWH)
My theory is the main difference between CWNS and CWH will be the bit stream
decoding logic. The H-17 disk format is entirely different than the
NorthStar MDS-A series disks. However, the disk format is documented here:
A major problem with this plan is I do not have an H89 or any Heath
formatted disks. I am seeking a partner to collaborate on this project. If
someone would send me some Heath formatted hard sector disks, I will start
the investigating whether a Catweasel Heath program is feasible.
Please do not send irreplaceable originals or critical data disks. I need
working disks you can afford to either lose or be damaged as a result of
testing the software. Please contact me offline or reply to this message if
you are willing to help out.
