convert RX01 to RX02?

A couple of the items we "saved" this weekend from the garage in MN included both an RX01 and an RX02 floppy system. Unfortunately, the mice got to the RX02 before we did and really had quite the palacial estate inside the cardboard box with foam packing that held the unit. Needless to say, everything that comes out of a mouse pretty much covered this drive system. Mouse effluent #1 turned the whole thing to #2. It looks to be a total loss. However, the RX01, in another box, was tightly wrapped in plastic and appears to have survived. Also obtained were a spare set of RX02 "formatter" boards, which are the electronics that go in the chassis and sit above the drives. Does anyone know if a pair of RX01 drives and power supply can be converted to an RX02 by just changing the formatter boards in the chassis? Were the drives themselves different? or did they get to double density by just changing the formatter? Chris -- Chris Elmquist
