BUT, the Horizon can also manage 8" drives (SSSD soft-sector CP/M
standard!) with appropriate controller, or use other S100 FDC boards.

Really? not any of the MDS (SD or DD) controllers as they only know hard

and use that as the system monitor to boot
stuff to disk.
The standard NS controllers have only a small rom enough to boot a NS SD
or DD floppy using their controller
where the roms are.

  The older
of mine runs a MDC4 765 based soft sector
controller and is an active highly modded CPM system. The other is
vanilla and tucked away.
Really, I just assumed that you could install a non-NorthStar disk
controller, in addition to the stock one, or maybe instead, in order to
be able to do soft-sector.
