In short, MSCP can't do it. Don't matter what SCSI can. You are limited
to what MSCP can do, since it is a MSCP controller. What it talks at the
other end is pretty irrelevant.
There was a special-order option for at least some CMD controllers
that allowed you "raw" access to the SCSI device, all packaged
up and delivered through special MSCP packets. I saw this used
in the 80's with laser-disc type storage but have not seen it
since.
Emulex sold UC07's/UC08's with special firmware for talking to
some optical-write-once SCSI things too, but I think it hid it
all behind some normal-ish (not "raw SCSI over MSCP") MSCP stuff.
At this point it's probably easier to just put a NCR 5380 on the
Q-bus or something. Heck, that was probably easier 20 years ago :-).
