Done! See http://minnie.cs.adfa.edu.au/Vtserver and 
http://minnie.cs.adfa.edu.au/Vtserver/vtserver/vtreadme.html
for details.

At the present I have Ersatz-2.0 running as a PDP-11/34A, one RK05 and
just the console. I have my tape server connected to the serial console
line, and I'm bringing in an RK05 disk image:

Virtual tape server, $Revision: 2.0 $ 
Running command stty -f /dev/ttyid1 9600 cs8 clocal -crtscts

Tape records are:
   0 tinyboot
   1 copy
   2 root.img

Opening port /dev/ttyd1 .... Port open

So no need for DZ-11, but many thanks to Norman, John and others who
wrote code for me. I'll probably still try to add DZ-11 support.
