You'll want to look at the developer note for the Q900. The
Q950 is
mostly just a faster Q900.
Actually... Reviewing that briefly, the IOPs were used in
the IIfx,
too. The Q900 uses IOPs for floppy, ADB, and serial I/O
(but with a
compatibility setting to make them act like the standard
serial h/w).
So I was wrong about the IOP driving SCSI, but I see that
the DAFB has
some control over SCSI, as in the Q700.

As far as I know, just the Developer's Note. And perhaps
Linux sources.

Oh, OK. I was just ducking through East TN on the way to
& from family
over the weekend. I can deliver one at some point, then...
