One that's on my list of favorites: Commodore D9060/D9090 - 32 sectors
of 256 8-bit bytes per track... possible, but not ordinary.

Fortunately, it's possibly to hack/trick this device - at least the
internal intermediate interface is SASI... not as bad as a machine
with an ST506-style interface integrated into the main board.

Of course, in terms of emulation, one could emulate that drive at the
IEEE-488 level with anything that was handshake compatible with PETs
(6502-bit banging, not high-speed controller chip-driven), and
understood the dozen or so Commodore DOS commands...

But at the ST506-interface layer... it is nothing like what was used
with DOS PCs, and would not be happy attached to a Linux box.
