hello as I already mentionned ,thanks to the job of
our friends in Russia , lots of information is on the group of google for
bk0010
http://groups.google.com/group/bk0010/
including complete schematics of the bk0010 that uses k1801bm1, in djvu
format (use djvu solo
to read)
this company make processors
http://www.angstrem.ru/index.htm
in particular the 1806bm2 that is pdp11/2 compatible and also a pdp11/23
compatible
this company makes peripherals
http://www.angstrem.ru/index.htm
in particular the 1582bj3-123
that is quite close from dlart (dl11 compatible uart+rtc)
datasheets are on their site .also on their site are  schematics of
application for complete system .You can use babelfish
to translate,it works well.I do not speak of word of russian
but when there is a will to communicate it becomes easier.
those chips can be bought at:
http://www.rtkt.ru/ that has a page in english
from the price they say new chips (processors and dl11 compatible uart) cost
about 40usd each.
Hope this will help to make things simpler.best regards
