in general, everything about keyboards is here...
any real spektrumist probably had at one time
zxХ8 with a standard 40-key keyboard. so small
beautiful. it was almost always carried out on separate
plastic buttons that were soldered into the board. a
the button consisted of two parts - the actual basics
the second part is also soldered, which moves when it
press!
when you press it, it closes two pairs
iron contacts and the switch works, it couldn’t be simpler
in short! when I had one, there were some buttons
when they stopped working, I did this:
he hit it hard with his finger and hammered it into the board.
I probably wasn’t the first to come up with this method, and it’s clear that
Because of this, nothing started to work normally. this is
bad, so you could check, nodid it fall off
on the board there is a contact pad to which this button belongs
npubapeha. if yes, then that's good! and if not, then
Something happened to the button itself. By the way, there's more inside
there is a spring, you can stretch it, it will be so long
- very long! and throw it away later. because you're back
You can’t squeeze it now, think over your head first
it was!
well, in general, try to compress it back and read
bye further...
most likely and most often, something happened to me
contacts that live in the button. for example they
oxidized or bent too much. if the glands
if they were oxidized, it was necessary to rub them with something, for example
screwdriver, rub - in the sense of scratching (from the word
scrape), of course from the side from which they
touching!
then it would be nice to wipe them with something, ideally -
if with alcohol, so that they don’t oxidize again... of course,
contacts may notoxidized and simply bent
too much, or, if you scraped them carelessly, finally -
fuck off!
well, what can you do - now you need to change the whole button.
more precisely, change the lower part of it, maybe on the upper
a piece of paper with
with inscriptions or film (you won’t believe it - with inscriptions too!)
and since the new button doesn’t have this piece of paper, then it’s not for you
needed (it will mislead you - what is this
for a button like that without an inscription?) are you going to press it?
constantly, to see what will happen, etc...
a nothing special will happen.
in general, using a forty-loaf keyboard is difficult.
but it is possible. then (later) the bourgeoisie came up with the keyboard for 58
keys, and we began to produce a copy of it, one to one!
Just the sight of her makes me tremble. that's true.
simply a classy keyboard - I dreamed about it for a long time and saw it for a long time
her (not at home, of course). she already has the design
the other, ale - progressive! nothing shorter is cooler,
than extend - keyboard from Spectrum! and finally, Spectrum without
Spectrum keyboard is not Spectrum!
such things have not been around for several years now
produced, but so many of them have been produced that there will be enough of them
- to all spekkmans! you just want to, but you don’t want to
fly away into space and get such a thing!
in general, the most important mission of any spektrumist living
in 2003 (and later) - collect these claves, buy them,
repair, wash, and put on a shelf. that's it
the rest can be taken from pisishniks, but these are the keys
can't be found anywhere! if they are heakypatho to the user and
spread left and right, they will soon die out like
dinosaurs and there won't be any of them on earth! seriously. Such a keyboard is based on a rectangular piece of iron, on
it contains special films on which current is sprayed
- conductive paths. There are several layers of these films, maybe
in addition to the main forty keys, we also need to create
additional ones, which, as is known, are being implemented
by pressing two regular ones at once. so there
so many layers of film.
well, on top of all this equipment there is a plastic spoon
garbage, on which there are buttons, each has a spring.
you press the button and the spring presses on the films and they
touching.
what's wrong with them? and the steam is all in trails
film, which lead out of the keyboard to them
I connect special connectors, the little blue ones,
plastic. and wires are already soldered to them.
these trains are about ten cm long, along the entire length they
covered with a protective coating, usually bluish
colors, underneath ithiding the paths! current at camobo
there is no end to this trail of this coating so that you can
connect the connector to it. and this coverage is not available yet
the other end of the cable, where it enters the keyboard
(erotic as I put it).
if you touch the track with your finger, then after a while it
time will oxidize and noteheet and will stop doing its thing
case, and you have several buttons turned off at once.
spread its tentacles!
but the track can oxidize itself, without your help,
just like that, or when you spilled something inside the keyboard
by chance. not on purpose.
in general, take scissors and now cut the train almost under
root, leave the part that is uncoated and
put a plug on it.
don't breathe, otherwise you'll get scared and don'twill be dressed.
if again the keyboard stopped plowing, when are you
tried to give her delicious beer, now you have
last chance, I came up with this bullshit myself - cut it off
the train is completely so that it doesn’t stick out and make a couple of these
a scarf, on which, how to explain this, in short from
enough for eight wires to stick out
solid, for example, as output from rubber bands, length
cahtumetpy approximately.
the main thing is that the step between the wires is standard - 2.5
millimeter. Solder the wiring to this scarf. delays
Wipe with alcohol and don't touch.
then slightly loosen the screws that clamp the cables
entrance to the keyboard and insert wires between these films,
which stick out from the board. align them exactly with the tracks,
check again and carefully tighten the screws back.
the scarf should be pressed.
some stuffwiring there, stupid, wow
say...
a, I completely forgot - in this form, with a scarf sticking out,
The keyboard will not fit into the plastic case, so
gently bend it before or after squeezing (it’s probably better
before). well, in the sense, not the itself, but soldered into it
wires - so that the scarf is parallel to
keyboard.
if everything works, !carefully!,without breathing too much,
close the keyboard and don't open it again, I
I have developed a rule for myself - if the keyboard works,
that means there is no need to open it if you don’t want it to
broke down.
and for me it already works and works and works! never
I won't take it apart anymore.
press the buttons lightly, do not press it all the way,
it worksmuch earlier, check! a play on
joystick - don't feel sorry for them...
by the way, wrap it in some kind of soft film and seal it
tape it on the bottom - this way it won’t get dirty and they won’t
erase the inscriptions. Here.
by the way about the connectors that fit on the cables -
We can’t buy them anywhere in the city right now, I think
The situation is similar in other cities. that's why I
I came up with the idea that you can make a scarf on which
there will be eight tracks with a standard step and a second
same shape, current without tracks and fasten them together
two buhtukamu with nuts (on the sides), tracks inward.
you relax the screws, stick them between the scarf
cable and clamp them back with screws. and the wiring in
solder this scarf. That's the kind of inventor I am.
easy and nposto.
