Hi Cory,

We can take this a off list if you like.   I warn you the DMR/DMC support was for BSD was rudimentary, and most of us in the UNIX community did not mess with it because we had non-DEC Ethernet controllers from that time.    You might have more success seeing if we can dig up a simulation of the Interlan or 3Com Unibus boards which were what may of used.

Hello all, recent subscriber to this list...but some might recognise me.

I'm currently fighting (and mostly succeeding) with getting a pure 4.3BSD-Tahoe install rolling in a VAX simulator (all my tape drives are currently nonfunctional or I'd fire up a real II or III).  Still in the middle of compiling (I know there are easier ways...but I like the feeling of doing it purely "from scratch"...feels more historically accurate).

Anyways, while waiting for the compile I ended up with a working 4.1c installation and I began poking around its source tree (I also did a little bit of poking at the CSRG discs).  I stumbled upon the fact 4.1c supports the DMC (which SIMH git now emulates!) and I see it's also still in src/old on some versions of 4.3 (I wonder if it'll still build...). Looking at the source is immensely confusing...does anyone have any knowledge/notes from the time period/documentation that will help me with my little experiment in archaic networking? I might just be tired...but the berknet configuration doesn't make a whole lot of sense to me. (There's also the fact my grasp of C is minimal).
