hello
here(among many others places)
http://www.emuverse.ru/downloads/computers/
lots of docs on bk,dvk,uknc series,all pdp11,all use those processors,lots
of schematics that can help in understanding how they work,of course all in
russian,
best regards

I wonder
if anyone here want to try to build tiny PDP-11 compatible
computer using KM1801VM3B CPU. This chip still available in small
quantities (price range is $10...$35). The system could use an
microcontroller such as ATmega1284 and/or big CPLD to emulate all
required peripherals. There were systems using this chip, but
unfortunately most of them contains enough gold to became firstclass
target for gold scrap hunters. So, it's very hard to find working system
today.
Here is related link:

...have three of them and some VM2 too. I where interested in such a
project. Currently I'm trying to build ans SBC out of an VM2 with some
old Tesla MVB1012 Chips (AY5-1013?) and a CPLD...
