hello
here you will find several issues of 'bk revue'
http://bk0010-private.leob.com/PK-BK/
it is about bk0010 that uses a
K1801 VM1
that is a pdp11/03 compatible,in this revue you will find lots of
schematics ,data sheets with time diagrams ,(all this do not require the
understand russian language),explanations ,programs,
also on
http://www.emuverse.ru/downloads/computers/
you will find lots of docs about bk,dvk,uknc all use the same processor,all
this should help you in building your own system.Those microprocessors are a
part of a big serie ,gate arrays in fact,this family called kr1801, has
several useful members:
KR1801VP1-128 is a fdc used in bk ,and uknc
KR1801VM1 is the 11/03
KR1801VP1-065 and KR1801VP1-035
are serial controllers (dl11 similar)
All those are easily available in russia or around ,new ,in shops,and are
not expensive ,the KR1801VM1 costs 1.01euro=
1.42usd at http://www.evita.lt/en/p-catalogue/(yes a pdp 11 for
1.42usd!!!this is really minicomputers for everyone ,Ken Olsen had not
dreamed of that)
I was not able to find data sheet ,but schematics exist where you can see
their use:
in the bk0010 ,or uknc for the processor,un the uknc
and dvk for the serial controller,here for the fdc of uknc
http://www.sensi.org/~tnt23/uknc/
I would sure find others things...
It seems others chips exist for example a dma controller
be careful in looking at the packages ,I found that some of the circuits
are labeled in latin alphabet ,some in cyrillics:)))
I hope this will help in clarifying thing,best regards to all

I have raised the issue of documentation for the
Soviet parts with a
fellow who posted here recently who lives in Moscow. He will help with
getting documenation translated if it can be had.
Just getting scans of the documentation in Russian would be a huge step
forward. I've dealt with Russian datasheets using Google Translate, and
have several friends with varying degrees of fluency in Russian. In fact,
I'd personally much rather have scans of the Russian documentation than to
have a translation but not the originals. (Having both would be great!)
