Most Qbus SCSI adapters emulate MSCP. Thats very nice. You can use any
SCSI disk with any OS that has a MSCP driver. And many PDP11 OSes have
a MSCP driver, as this is needed for popular adapters like the RQDXx,
KDA50, UDA50, KFQSA, ... My Dilog DQ706A e.g. emulates a KDA50 and maps
every SCSI disk or CDROM to a RA80 (with different size).
