If I could get 22disk to actually play nice with this thing, I'd definitely
buy a license for it. :))
Well, I think you're making some basic errors. Every PC/Compatible in
the world can write MFM; the FM-capable ones are in the minority (all
standard DOS disks are MFM).
Second, you can't write 26 256-byte FM-encoded sectors on an 8" track.
26 128-byte, yes, but 26x256 is definitely in the MFM arena.
Try formatting up a SSSD 8" floppy using definition A1--DRI's standard
CP/M distro format for years. See if your 820-II like it.
