Here's what I know:

Rob Jarrett ported a KDP simulation to the latest emulator.  It didn't 
quite work.  There's a personal repo on github, but it's not worth a 
pointer.

I have 2 -10s and 2 -20s  configured for DECnet (and ANF-10) running on 
my desktop. (!)  No 11-based ANF nodes yet.

I made some progress - I had ANF-10 up for an hour or so; DECnet-10 not 
at all; DECnet-20 sometimes.  The KDP emulation is missing some commands 
that the OSs count on.  My code isn't in the repo, yet.

Mark Pizzolato has a DUP emulation that he says is mostly working on 11s 
and VMS.  Rather than keep two DUP emulations, the plan was to split the 
KDP into the KMC + DUP, rather like the real hardware.

I've been off line for about the past 10 daze - e-mail appears and 
disappears on my servers - the responsible party calls it an 'upgrade', 
so I'm not sure what the current state pf the KDP/DMR work is.

I have tracked down the COMIOP-DUP microcode USER's documentation with 
the help of Al Kossow and Cynde Moya, and it's on bitsavers along with 
the DMR tech manuals.  (Both even agree with my memory.)

and

also

Once I catch up on e-mail, I'll see what I can do to help, depending on 
where Mark and Rob are.  (They may have given up on me  due to my on/off 
(mostly off) mail service.  Hopefully that's fixed.)

I have 2,475 e-mail messages to sort thru before I'm up-to-date...but 
should have some time this weekend.  I hope.

This communication may not represent my employer's views,
if any, on the matters discussed.
