@abzman, you'd just need to use a 10 hard sector HFE image. Single density and double density use the same file type for HFEv3. And there's not any real advantage to single-sided HFE. I've attached some blank disks created by mk_hfe.py (10 and 16 sector, 40 and 80 track). Either of the 10 sector ones should work for you, since it seems your system uses 35 tracks.I'm going to be getting into trying this in a single sided single density polymorphic systems hard sector floppy controller.
I searched around briefly and didn't find documentation for the on-disk format. If nobody knows where it is documented, you could share an HFE file later and it probably isn't hard to reverse engineer. Then we could have a pm2hfe converter.
