[sdiy] Russian divider chips..

[Bob Weigel]

KP1012( backward N )K3 for example (don't have a cyrilic character set 
handy...) hehe.  Or the same ending in n1 instead of K3.   There are 
tons of these under the keyboard.  I see some signals coming in probably 
but the whole thing...1) I can't find a ground reference on any of the 
boards!   2) from the diagram I found, on this site

http://www.155la3.ru/dsheets.htm

the image shows a chain of TT's or..flip flops I assume and then..HS's 
coming from the Q' out....I assume... those are some logic gate maybe.  
They used square boxes to symbolize them though..  I don't know.  I 
can't read the descriptions.  Does anyone read that language here?  Any 
help appreciated..particularly

1) What is pin 16?  Appears to be 10K front loaded from the 15V source 
on the K3 suffix'd chips.  On the others (most of them) with the n1 
suffix they go to individual wires
2) pin 8 is common to 5V source on K3 suffix's chips. There is 10K 
resistor between the common connection of the n1 suffix'd chips and 5V. 
   I'm only seeing 15V, 5v and ground coming from the power supply.

Only 15V and 5V and 59 other wires attach to each board.  There are 4 
total boards.  Some of the wires are parallel but most appear to not 
be.  Haven't traced them all out to figure out the pattern yet..anyway 
12 of the n1 suffix chips and 6 of the K3 suffix chips per board!  ie. 
total of 72 down there.  Any insights appreciated.
