Nope, it's the 8250LP-style drive mechanism, with two separate cables
for every drive (so 4 connectors on the mainboard). In fact, you can
connect a 8250LP or SFD1001 drive to the C900 and it will work (however
the TPI density will be different from the original drive). So no real
reason to connect the only drive as #1 not #0.

Now I remembered that even the Coherent system for C900 has /dev/fd1 but
it does not have /dev/fd0 (though you could make it with an utility like
mknod).
