Iron - on the system bus, set me on my ZS Scorpion 256.

  In this article I will discuss the system bus, set me in my 
Scorpione. On it, I casually mentioned in the previous issue of 
the newspaper. Now I want to tell you in detail. 

  I'm not going there to act as a certain
standardizer and unifier "iron" Spectruma,
experience shows that the previous ten years or more
it is a thankless and futile. But, as I
thought, many happy owners Scorpiona
not only the system bus, but even the system connector is not 
installed, and since we live in a small town and a man who 
collected some a new peripheral device is very easy to meet and 
ask him for a device for testing the on your computer, then I 
think to connect this device is much handier to just sticking 
into the socket, not podpaivaniem 10,000 wires. In my opinion 
it makes sense to still collect a bus. But, well, I do not 
insist. Can write all peripherals, including proprietary system

bus in C. Zonova. Somehow I recently calculated how much
will be issued to almost all of its devices,
required to install the hard drive 40 MB + itself
Winchester. I got nearly £ 2,000 ...
Particularly pleased with the cost of postage - $ 5
minimum.

  Oh well. Now on my system bus.

  The first step in a hole under a system connector on the
PC board soldered connector SNP58-32 /
94h9V-23-2-8 (male), and 1A and 1B foot connector
installed in their corresponding holes on the
board, and the legs 31A, 31B, 32A and 32B (for which the holes 
on the board is not provided), unbent and fluster him the 
following signals: -5 V, -12 V, +12 V, respectively (leg 32B is 
free). 

   Then manufactured board composed of one
Built SNP58-64/95h9P-20-2-8 (female) and zaparallelennyh 4.5 
connector type SNP58-32/94h9V-23-2-8 ("Dad", in the last issue 
of the newspaper, I called them SNP64. I apologize as a 
connector of this type and all switching products together. 
Most of this does not happen again). 

  A connector contacts being "mom" needs to unsolder
relevant contacts in connectors, "Dad" and vice versa, the 
contacts in the "mom" to contact a "dads." The distance between 
razememi the board should take approximately 2.5 cm to the 
peripheral boards to be installed on these terminals does not 
close each other and with Pay kompyutera.Polezno also derive 
through plume of another "daddy", zaparallelennogo with others, 
at the front of the computer to connect For example, the 
programmer or external modem. 

  Made so board connectors "mama"
stuck in the manufacture of your same system connector
computer and, lo and behold, your computer will
system bus, consisting of 5-6 slots.

  Now in any of these connectors, you can establishes
Lebanon board having the slot "mama"

  And now for the line signals the legs of the connectors.
If you did everything correctly, the connectors on the legs you 
should get this nonsense here:
