So I'm in the process of pulling a bunch of files

So far (thanks to help from Howard Harte) I've got an 11/44 with an RX02
drive running RSTS that has the DD module loaded. I'm running the serial
tape drive simulator on a PC (I forget what it's called or who wrote it).
So I can do:
COPY DY1:*.* DD0:
Which then copies all the files off of the disk into an image file on my
PC. Works very nicely, albeit slowly (only 9600bps transfer rate).
Is there a better way to do this? I've seen various postings of people
getting RX02 drives connected to Linux boxen. How so? Has anyone done
this?
On my 11/45 running v7 unix, I "dd" the floppies I want into the
appropriate files on one of the disks and then use "tar" to write them
onto a 9-track tape. I then sneakernet the 9-track tape over to a PC
that has a SCSI 9-track tape drive and read them off. It turns out to
be *much* faster than serial.
It works *very* well and I use it in both directions...if there's an
image that I want to get from the net onto "real" media, I put it on a
tape and then carry the tape over to the 11/45 and write it onto the
appropriate media.
I also found this:

This is very cool. It's an RX02 simluator (hardware/software) that makes
your PDP11 think your PC is an RX02 drive. It would be great if I could
read the files from a real RX02 and then dump them into the emulated RX02.
Can a PDP11 have two sets of RX02 drives installed at once? If so, do the
second set of drives become DY2: and DY3:?
