I suppose
I'll have to add a simulation of the Unibus CH11 Chaosnet
interface to SIMH.
Why? Once 10M Ethernet hardware was available, people switched pretty
rapidly to using that, instead of the CHAOS hardware.
Because the 4.1BSD Chaosnet I have found only supports CH11. And also,
it would be useful for running MINITS and ITS on SIMH.
