I've been using Will Kranz's TU-58 emulator to do just this sort of thing, making images of 5 diskpacks that were included in a recent 11/23+ acquisition. Use a null-modem cable between the second serial port on the CPU (LPS port) and connect it to your PC's serial port. You might need a 25pin-to-9pin adapter, but it's just a standard null-modem cable in any case. On my 11/23+ the LPS port is set for 9600 (which I think was pretty standard), but I could go to 19.2K with some jumper changes that I haven't got the nerve to try yet. Your system might already be set to a higher speed. Experiment a little and you'll figure it out, or physically examine the CPU board. In any case, using such a slow speed for transfering 5MB or 10MB images definitely takes a while, but it is also definitely worth doing. You want to preserve that diskpack image! At 9600 a 5MB disk will take just shy of 2 hours. Check out Will's TU-58 emulator page at http://www.fpns.net/willy/pdp11/tu58-emu.htm J.
