There was a special-order option for at least some CMD

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.
Alphatronix did something like this with Viking controllers (both
Q-Bus and Unibus) with special firmware.
