Like the bdv11 (m8012).

Floppy disk can be RX50 or TEACFD55GFR.  If the controller is RQDXXX1 or 2
the disk will be RX50 or only one side of Teac (RX33).  If RQDX2 depending
on ROM rev it will be RX50 and or RX33 (800k).  You can bet on
RX50 compatability in all cases which is single sided 80track 10 SPT.
To use the teac you may require nonstandard jumpers [compared to RX33] on 
the drive to make it look and act like RX50 to older RQDXn though it 
does work fine.

The hard disk is st412(10mb), ST225(20mb), st250(40mb), Quantum D540 (30mb).
However they must be formatted with either xxdp or deom a system that can
such as uVAX2000 (for RQDX3 only).
