Where does one come by Ultrix sources these days, is it hobbyist licensable (or "abandonware"), and what hardware is needed? Should run on a MicroVAX 3900, haven't tested other systems using SIMH yet. It's more "abandonware" but licenses can be "made" if you know how. You can get install media from TUHS iirc.

Anyone got a working image / HOWTO on getting this going? For TOPS-20, you can enable DECNET in the panda distribution with not too much effort. I tried to explain how to do it here: http://ancientbits.blogspot.com.es/2013/05/ten-over-pi.html The main problem is the network setup. You will have to work in shared mode and it can wreck the host machine NIC. Aren't we mixing up a couple of things here? The Panda distribution, as far as I know, runs on the KL, which SIMH does not emulate. SIMH emulates the KS and right now you can't run DECnet on the KS. There is work being done now to bring the KMC/DUP emulation to SIMH to allow DECnet to run on the KS. You should contact the SIMH mailing list for status on this.
