           AY Rulez 4ever!!!


   Hello to all fans of the coolest
companies on the planet Earth! In this article
I'll tell you about how to make AY-shny
zvukan much steeper.

   So. You need to first pull the 22 th leg AY-3-8910 (or
15-th leg AY-3-8912) on board muzykalki.
Then connect it to the third leg circuit
155IE7 (1533IE7), and-and-SIR .... and all!

   Well? See the difference?! Not
Is it true Kulnev?!

P.S. I have not been able to verify
Does this revision to the Scorpion, but
Pentagon'e will work!

    Campaign is meant that IE7 that
clock ...

    In this process clock frequency
3.5 MHz (instead of 1.75) and the corresponding
change in tone frequency and noise.

              Hi Victor!


    Writes to you from Moscow user Kushnikov
Alexander (SANDER, 500:095 / 333.3). I read the signal issue of 
the newspaper ZX-Hard and I decided to write you because I 
believe that the creation of such a newspaper is now necessary,

as repair and maintenance of computer hardware platform is very 
bad. Due to the fact that no information on the

ZX gland, many people left the platform,
because they can not self-repair technique. I myself can not 
carry a to zhelezyachnikam, because not very well

versed in hardware, although the entire repair their computers 
and periphery do himself (y I SCORPION and PENTAGON-SOLON). 
Generally on I've been doing more computer hardware,

something else. During this time I had saved
enough material (diagrams, texts,
how to configure and more)
are pleased to share with you
for the good cause.

    Now, about the newspaper. Of course I would like to
see a much-needed newspaper in a pleasant,
modern form (I mean the reading room).
To do this, sending you two reading room. About the creation of 
the magazine believe that it is impractical, since the log is 
required a lot of stuff and Periodicity of the journal

less than that of the newspaper. There is also an idea to create
Guide to the newspaper, ie what material
where to look (in some rooms), but that when
will have a few issues. Also in the newspaper, you can use 
reference data of radio components, since not all users

there are directories such as chips
or transistors.


    Incidentally I have also the idea of ​​releasing their
newspaper. Subjects in her overall plan. If you are not hard to 
please write like your situation with SPECCY, if you have

net, as the position of the iron, how many
users, etc.? If you let me publish
your answer in one of the first editions of his newspaper. By 
the way the beginning of my letter (to transfer to send files) 
can publish. Yes, even if you do not come broke

please any applets. Write, you can send any scheme
or even some literature.

P.S. I look forward to future issues
Newspaper ZX-Hard.


                 Sincerely, Alexander.

    Position of the iron is really bad, but not because of lack 
of information on the ZX. Repairs are supposed to be taken by 
professionals, who for a long time have gained the necessary 
knowledge, experience, background and other literature resp. 
diagnostics, etc. equipment, etc. In addition, professionals 
are needed for the production of computers and peripherals, but 
among programmers and their now not so much.


    However I do not mind, but even with both hands, lovers, 
because from their ranks and come true professionals (here

need to shout Spectrum rulez, HRC sax,
Bill Gates lamer;)).

    At the moment, need to stay
fans help to become professionals -
That's when the situation begins to improve with iron.

    Another thing - take a user who does not
holding a soldering iron (by the way, on their PCs
for some reason zhelezyachnikami: open
housing (woooow ,...), changed the video card
(Coool. ..), and cool man - think you can
straddle spektrumistov), ​​and teach him
zhelezyachestvu. Tut's desires in addition to user
must be that same wealth of information, but
not to ZX, and a hardware in general and digital technology in 
particular. Himself Spectrum in the light of general 
information on the iron very simple as all genius;). To 
understand his work, you need to become familiar with Z80

(Desirable and command system), to analyze
skeletal scheme - the foundation of all clones, and some 
circuit solutions. The latter is best done independently 
studying patterns of different components. 

    Can be made about this classification:

    -User. A user goes to a professional zhelezyachnikam.

    Amateur. Knows circuitry ZX, well versed in it. Repairs all
himself.

    Professional. Hmm, and here the circuitry moves on the 
second plan. Much more worried about the viability of its 
product on the market, actually the market itself and its 
development, organization of marketing channels and (or) 
'Export Technologies' soft support, advertising ... 


    As for reference material (scheme
sorts, etc.). His volumes are large enough, and stretch it from 
room to room makes no sense. Best of all, perhaps,

make separate collections of applications without
any frequency and of the entire heap.
So send your all there is (and can even make them myself)


    Now for the reader. It marks exactly
year and it is high time to rewrite. I have long
thought and get it;) ...


    About the magazine, I now also think
that it is not needed. Now newspapers have become the giant ... 
(Buzz, etc). 


    References in p / detail in any
the newspaper did not vlezut;) - they are in separate
databases should be distributed. The newspaper can give 
information on most used parts, such as rulez all times and the 
people, the first native transistor in a plastic KT315, well, 
etc. Something like "reference sheet" magazine

"Radio".


ZH> Is there are a couple of letters ... But once
they are on paper, I had them properly
poskipayu. :-)

    ... I read in the ZX-Hard00 your call to
creation of zhelezyachnikov. Proposal
certainly interesting, but it is extremely difficult because 
zhelezyachnikov actually bit, and the distance between them is 
not small - to take us with you. Then there are problems of a 
plan: for example, have you decided to Speck card, and I 
figured out how the hardware can display sprites with a minimum 
of cases - we're we can never agree, because never met in 
person, and you understand that trust unfamiliar person 
information on which you can earn good money and famous, not 
everyone will. Do not think that I am currently writing - I am 
a fanatic warehouse, and Speck me nothing sorry, but you 
understand - people are different. But I like your idea, and it 
was would be nice to organize some kind of commonwealth

zhelezyachnikov, at least in terms of information sharing - 
will be less than 'reinventing the wheel'. And then, at least 
like and sell everywhere books and reference books on 
microelectronics, but find something on the chips, used, for 
example, in modern computers, almost impossible ...

    Must not create a group, but something
sort of association. Although these limits to anyone not
needed. It is rather a call for cooperation
that exists now and where you want to connect more people.

    Distance - it is not an obstacle to cooperation, and 
perhaps even some Plus, as a demarcation 'of zones of 
influence'. 

    About ideas. There are a whole bunch of ideas, but here's 
to earn them a lot of money for some reason, nobody rushes ... 
Because brake not a lack of ideas but lack of production and 
market. 

    In general, circuitry - something important, but
in our case is more complicated problems. Now more important to 
do it than to invent the idea. 

    The costs of design can be
reduce, if you create a kind of information space and a bank of 
circuit solutions.


    About modern ICs I want to say
In most cases you can do
without them. And since electronic components away from
capitals of the poor and colored only PTs'shnym
rubbish, it has, we'll have to settle for TTL loose and others 
like her.

    ... Newspapers and magazines are now divorced
a great many, but special editions there is none, and it is very
bad. Information on Spectrum sprayed
For the publications, and very good to have found
people set out to collect
together at least some of this information ...

    ... Hopefully, Victor, that the idea of ​​publishing
"ZXHard" still alive and you continue the
case. Publish a newspaper, not having a "regular"
coders, artists and musicians, of course
just hard, but it's not major problems, and
technical and ephemeral - not today, but
Tomorrow is ...

    Throw this thing I'm not going. Delay can:) and quit - no.

    But in general, thank you for providing the
materials and give thanks to Fast
