You can transfer files to these floppies in two ways:

	1) Use the DECUS utilty VMSFLX with an RX50 drive on a MicroVAX.
	2) Use the RX50 driver for the PC/AT (high density drive).  You can
		get this from SIMTEL.

Neither utility will allow you to format the disks, but you can read and
write them.  I use a $$ program called UNIFORM for formatting.
