MSCP controllers and drives should all appear to the OS as DUxx type drives,
so it shouldn't be an issue.

Jerome Fine replies:
There is a list of DEC boards available. I can't remember the
address. It lists the M8190-AB as Qbus.
2.11BSD, is the disk controller supported?
Probably. MSCP on DEC PDP-11 systems seems
to be supported by most operating systems that run
on a PDP-11. Most 3rd party Qbus disk controllers
and host adapters, especially SCSI host adapters
supported MSCP since their use was targeted to
function under DEC operating systems on the PDP-11
and microVAX II systems.
Sincerely yours,
