Getting Arpanet back up is tricky. I think only KLH10 has decent IMP
support. Not much of UNIX history runs on that.
There is the H316 emulator in simh, but its IMP-host interface would
need to be fleshed out and the corresponding host cards do not exist
yet in the simh VAX/PDP emulators.
I did a bit of the fleshing out; it can be found at:
https://github.com/charlesUnixPro/simh/
on branch dps8m.
The 'ready' bits on the interface needs some work. The "cable" is
implemented as UDP packets; probably the code should periodically send
packets if the interface is enabled and the other end should keep a timeout
counter to detect the other end not ready.
