well know) a very high-level interface (MSCP) to the host; I'd guess,
and this is just a guess, that low-level stuff like sector interleave
are handled entirely within the controller. Anything else would present
a big abstraction violation, jumping over the MSCP layer, which would be
pretty non-DEC-like for the time.

Yes it does.
It formats at a different interleave level than the
RQDX3 using the bootable uVAX-II diags. This results in lower data
transfer rates on the RQDX3.
Anyone know for sure if formatting with the uVAX-II diags and the PDP-11
XXDP diags will result in the same interleave with the same RQDX3 attached
disk?
