The NorthStar Horizon also uses hard sectored floppies.

If you just want to use the HS floppies, the Apple II can use either hard
or soft sectored floppies - it ignores the sector holes.

I picked up 3 or 4 boxes of brand new hard sectored floppies years ago.
Never opened them, they're around here someplace.

FWIW I have a Xerox 8080 based machine that uses 8" floppies, and I
also have a CDC Z80 based machine (it has 3 processors and a touch-
sensitive screen) that also uses 8: floppies.  Neither of them has a hard
drive, but both of them have two floppy drives.
