hello Andrey,yes I think of it ,but I do not have enought time.
I have several bk0010,and Uknc in working condition,I have processors and
also the periferal circuits (kR1801VP1128 the fdc ,and ,55,and 65 the dl11
compatible circuits,with the specific xtals ).
I have designed models with eagle to design pcb,I think the use of a simple
console program like the one of 11/34,its listing is on the net the .hex
also ,it can be burnt easily into two eproms.
You can have an idea (in french) of my machines here:

Subject: homebrew PDP-11 using ancient USSR chip
Hello All,
I wonder if anyone here want to try create tiny PDP-11 compatible computer
using KM1801VM1B CPU. This chip still available in small quantities. The
system could use an microcontroller such as ATmega1284 and/or big CPLD to
emulate all required peripherals. There were many systems using this chip,
but unfortunately most of them contains enough gold to became firstclass
target for gold scrap hunters.
Here is related link:

Thanks,
Andrey
