Did you get the newer-revision one with more RAM?
Was running RISCOS on it but got bored by the awful interface.
Hmm, Wonder if it'd be possible to modify the interface. I hear it has a package manager now or something?

Which Pi do you have?
I'd be willing to help with a SIMH-VAX distro for the pi. I've been wanting to write crappy shell scripts to generate simh configs anyway.
Sampsa
OK, so I'm quite lazy - does anyone have a prebuilt version where I could just tweak the SIMH / VMS settings? :)
There will be beer for any assistance should you be crazy enough to visit Helsinki.

I've got LAT running in the Pi as well. I haven't tried DECnet yet (I'm not sure if the ARMHF kernel has it compiled in, and I am _NOT_ going to buld the kernel in the Pi since it could take whole days :)).

I do. It is realy easy to do. If I recall it correctly you need to do (after setting up the raspbian distro):
$ sudo apt-get install git
$ git pull https://github.com/simh
$ cd simh
$ git checkout v3.9-0 # This is optional if you don't want to build the HEAD version
$ sudo apt-get install vde2
$ sudo apt-get install libvdeplug2
$ sudo apt-get install libvdeplug2-dev
$ sudo apt-get libpcap-dev
$ sudo apt-get bridge-utils
Then you can build the emulators you want to use. I recommend to build just what you need, since compilation takes a little bit in the rasp-pi:
$ make vax
$ make vax780
$ make pdp11
$ ...
I am pretty sure you don't need anything more. And if you don't want to use vde then you can omit those packages too. If you use vde then you will probably want to set up your network using a /etc/network/interfaces file similar to mine:
auto lo
iface lo inet loopback
#iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
auto tap0
iface tap0 inet manual
vde2-switch -t tap0 -n 16 -s /tmp/vde.ctl -M /tmp/vde.mgmt -m 666 --mgmtmode 666
auto br0
iface br0 inet static
address 192.168.0.8
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.128
bridge_ports eth0 tap0
up sysctl net.ipv4.conf.br0.proxy_arp=1
(The wlan stuff is not really necessary, and of course you must modify the adresses acordingly to your own configuration)
With this setup I run 5 simulators in a single Pi, including a vax780 running VMS 4.7 working as my area router. Oh, I run Johnny's bridge in the Pi as well :)

We could pull out a LOT of cruft from a full install and optimise it if we were to do this. Can SIMH build against uClibc?
The first RaspberryPi system I bootstrapped SimH on was running this:
http://www.linuxsystems.it/2012/06/raspbian-wheezy-armhf-raspberry-pi-minim…
It's bare-bones and has no cruft, might be a good starting point. It hasn't been updated in a while though, I don't know if it's staying with the current package stream for Raspbian or not.
