Not really. You can use any standard 3740 formatted disk (i.e. 26 
sectors/track, 128 bytes/sector, 77 tracks, FM) and change it to RX02 
formatting in an RX02 drive with
.FORMAT DY0:
or change it back to RX01 with
.FORMAT/SINGLEDENSITY DY0:

In both cases you need to
.INIT/BAD DY0:
to create the directory.

Only a /slight/ overkill...
