So this might be relevant. If the reported size is sufficiently different, things will
break.
For MSCP, RSTS cares about the device size (LBA count). It pays no attention to reported
"geometry". It displays the reported device type string (in INIT "Hardware
List" option) but it doesn't care about what those are. If a gigabyte disk
claims it's an RX50 (or an RX98), RSTS will happily display that string without any
objections.

I have a CQD=220A/MT configured for 6 disks and one tape.
As for disk types, you can toggle RA ON or OFF on each drive.
You can specify one RA type that will be in effect for any
disk with RA ON. Types are: RA70, RA80, RA81, RA82, RA90 and RA92.
Looking at this further, I don't believe the CMD CQD RA type option
does what you think it does. I don't believe it has any effect on the
reported geometry of the MSCP unit, I believe it only changes the
reported type name of the MSCP unit.
