Has anyone ever used vtserver to copy a physical pdp11 disk to an image

I know it is usually used in the other direction, copying an image to a
real disk.
A local pdp11/34 has popped up, and there are several RK05 packs
I desperately want images of.
Also, I seem to remember some discussion of a version that could auto boot
with the 11/34 console emulator, instead of ODT...
As always, thanks for any info.
Maybe I misunderstand the question, but if you have a spare DL11-W
that you can put in the /34, configure it at 176500 / 300 (IIRC).
Then the /34 thinks there is a TU58. Get Don North's TU58EM.
You can boot the /34 from the virtual "TU58" *and* then dump
(piece by piece) the RK05 to the second attached virtual TU58 tape.
It's not fast, but it works.
Another option, if you have that hardware, is the RX01EMUL board,
with an M105 and M7821. That connects to a PC parallel port and
mimics an RX01 floppy drive.
I have never tried to boot a PDP-11 via RX01EMUL though.
I *did* boot an 11/34 using TU58EM from a Toshiba "laptop"
(VHS cassette sized mini PC). Was kinda fun to see a big computer
boot from such a tiny PC. Nowadays you could use a Raspberry, etc.
