I'm going to use this one:
http://simh.trailing-edge.com/kits/uv7swre.zip

So first I'm going to create some temp directory and place my pdp-11 exe
there....

Then let's unzip the zip file..

C:\Temp\uv7>unzip \Users\jsteve\Downloads\uv7swre.zip
Archive:  /Users/jsteve/Downloads/uv7swre.zip
  inflating: AncientUnix.pdf
  inflating: unix_v7_rl.dsk
  inflating: README.txt

Now I'm going to create a small ini file, and put the following into it:

set cpu u18
set tto 7b
att rl unix_v7_rl.dsk
boot rl

With that done we can boot!

PDP-11 simulator V3.8-1
Disabling XQ
@

Now with the boot block executed, we load the boot programme:

@boot
New Boot, known devices are hp ht rk rl rp tm vt

 : rl(0,0)rl2unix
mem = 177856
#

We are now dropped into single user mode.  I'd probably change the root
password.

# passwd root

Anyways hitting control+d will kill the single user shell and bring it up in
multi user:

You are going to have to rebuild a kernel to enable the dz support... I'll
have to try that later.  But this should be enough to boot up.

No worries.
