Basically this is what I've done. Though I think I had the block size
seriously cranked down (no idea if that matters). I first went to an image
file, and then I FTP'd it to my Mac and burned it to CD-R (I didn't have a
CD-R attached at the time).

Stuff your RX02 images in an RL02 image using PUTR.COM, then you just need
to get the RL02 image onto your RT-11 system (I have TCP/IP working on my
PDP-11/73 so I just FTP it).
