This would be the Right Way. I've got my PDP-11/73 set up for that, I still
need to build the kernel driver for the Ethernet interface and get TCP/IP
going. I have dozens of RX02 floppies to work through, much faster than
serial, and the vtserver `rx` driver has a bug in it anyway where it
continues reading past the end of the media (not harmful to the disk/drive,
but you have to sit there and watch it).
Thanks,
Jonathan

My method of creating images of several RL02 disks was to set up a
PDP-11 system running 2.11BSD with an RL02 controller and Ethernet
interface, then 'dd' the disks to image files on the local system and
then FTP the image files out to a modern system. Still seemed slow,
but not as slow as a serial port connection.

for use with SIMH or E11 or whatever.
Yep. I backed up the RD52 in a new-to-me MicroPDP-11 and it took hours.
Be advised, it takes a *long*
time, even on a 11/73 with the serial port turned up to 38400 bps.
Has anyone done any console serial port hacking for speed on Qbus or
Unibus? On something integrated like a KDF11-B it might not be so
easy, but maybe a DLV11J or a DL11W?
I'd think hitting 115200 would be really sweet, if everything can keep
up. Totally worth some experimentation to see what part gives out at
ludicrous speed.
