[TUHS] running BSD 2.11 on my PDP 11/70 emulator

Hi,

For fun I'm developing a PDP 11/70 emulator. It runs on everything from 
ESP32 microcontrollers up to linux, windows, etc
https://vanheusden.com/emulation/PDP-11/kek/
Currently it can run UNIX 7 in multi user mode.
Of course I would like it to run BSD 2.11 as well (because of the 
networking support). It boots, but after outputting the memory amounts 
it produces a lot of garbage. It does eventually complete booting and 
then allows you to log in.
I wonder if you sees this:

(image), does this ring a bell to anyone? I verified with simh that the 
disk-image should work.
