 Well, nakonets-all zhelayuschie, dazhe in otdalennyh ugolkah
Spectruma universe, can sobrat currently on mouse controller.
Srazu want zametit that danny material rasschitan purely nA
more or less prepared by the public, that is, those who at 
least raz (Better not raz) sdelal something, and

it's something he zarabotalo. In
Due to these obstoyatelstvami in
dannoy state will not be detailed
opisany, HOW yes why something
rabotaet it tak and inache.
Just rekomendatsii on zamene and
otladke.

 Itak that we have. We have
block counters (nA figure pokazan one block, a second, because 
of their identity, first in To save CAREERS no pokazan

(Although pokazan sprava kvadratik
takoy, with a dotted line (if
tak can vyrazitsya :)))). Block
is simple: the counters schitayut a plus
or minus, depending kuda lead
mouse. Because the counters
sami on its own four razryadnye their
had to combine parami. But
it is not vazhno. Tak here, 8-bit single koordinaty (kakoy not 
vazhno) nA scheme marked, well skazhem

tak, conditional C0-C7. Accordingly, for the other koordinaty
C8-C15 (zabudte of the third and
fourth dimension, poka y vas
No under the table POWER-Amiga;).
Tak Now, these naschitannye koordinaty popadayut nA 
multipleksory, that actually carry them to the bus kommutatsiyu 
dannyh protsessora (if you do not ponimaete

about that question, go and buy yourself DENDY, and pytaytes
understand anything, not for all vas
it! ). Tak here, kommutatsiya koordinat is one signaltsem ... 
Signalets toozhe with protsessora and nazyvaetsya he A10. 
Address that is. But he only commutes, a in those 
isklyuachitelnye times, kogda need

something that b - a all-taki popalo nA bus, there is a signal
razresheniya reading, which is generated in trivialnom 
deshifratore. Thus do the same this signala, Well nazovem its 
X1, by simple manipulyatsii poluchaetsya signal port blocking 
kompyutera on a tricky system to kotoraya

unverified dannym sovmestima
with the firm Spectrum and dazhe with
some zhalkimi his analogami
;). Figure blocking for those
Who dazhe not zhalky analog invoked here.


   IORQ
 (20 Z80) IORQ

 So it was ...



   IORQ 500 Om
 (20 Z80) OLD IORQ



    mouse IORQ mouse IORCE

 ... And so need it.


 Blokirovka postroena nA tranzistornom vein, which komande 
zazhimaet signal protsessora going to ostalnym ustroystvam (but 
not to this one) nA +. You can skazat that the lock can not 
delat, if vas, naprimer, Profi. According to pare

checks revealed that probably nA this mashine sdelana
dostatochno gramotnaya deshifratsiya.
You can check this fakt trivialnym reading of BASIC (a
takoy language) porta 64223. If
see 255, then unto you are lucky and
You can not stavit additional
block, otherwise a case of
nado delat all the full programme. All elementarno, HOW sami
you can see, although if there is zhelanie
HOW izvratitsya something, then we can
it sdelat and another naprimer nA 555LL1. But this is not nashi 
problem.  Now about knopkah. In fact,

You can podklyushit them at least eight
but who needs malo, yes, and mice
takih malo. Gramotney 3! Poll
buttons trivialno simple. Same
deshifrator delaet signal, well nazovem its X2, which blagodarya
occurs schityvanie mladshih 3
registra-bit keys. Raspolozhenie buttons on bitam follows: 0
bit - Levaya (glavnaya) 1 bit -
Pravaya (not quite glavnaya) 2 bits
- Medium (for symmetry). Takoe
raspolozhenie bits is a logical and samym naibolee massovym
among ostalnyh variantov. In
Danny was the first rasklad FIRST
and only in a rather massovom production and prodazhi dannogo 
devaysa large screen nazad Other period (according to this day 
nasha gruppa prodaet samy cheapest variant dannogo devaysa 
sm.reklamu). Although there were people sobiravshie it in the 
same period of time nA knees (chitay nA provodkah) and 
pytavshiesya sdelat pravuyu and the left button naoborot,

what has already been sdelano in nashem
a case of. In dalneyshem softmeykery
which obschalis with the type of delayut under his buttons, 
which were with Us - under nashi, well a those who came later 
pytayutsya delat AUTOCONFIG, that samoe gramotnoe. 


  Now for the mouse. Suitable lyubaya
passivnaya mouse (AMIGA Technologies, BUS-MOUSE, Search and ...
etc.). Tak can also teach any PC-RS232C mouse joint raboty.

 The list of items with potential
zamenami ... CT - 561IE11 can
zamenit nA 561IE14 if the findings
9 posadit nA + instead of land (not
of floral gorshka kotoraya).

MS - 555KP11 can zamenit nA
1533, 531, itp
'& - 555LA3 rekomendatsii HOW to MS
DC - 555ID3 rekomendatsii HOW in '&
R - resistor 1k small
power.
VT1 - tranzistor KT315, bukva not
has znacheniya
VT2 - tranzistor KT361, bukva not
has znacheniya

 You can postavit tak same few kondensatorov on the power supply
(If you're sobrali and it srazu
not zarabotalo (device) check: not zabyli-Do you connect the 
power supply nA chips ...) 

 Proverka countable module prosta. Take the lead (MGTF) and 
catches his nA kontakt PHASE A and earth. Zatem take a certain 
number of Hertz and their suem nA input COUNT A,

tak same kakoy take anything ostsilograf (or migalku nA krayny
a case of), and adding counters
Consider nA vyhodah signaltsy ...
They should be about ravny
main chastote divided nA
2, 4, 8, 16, 32, 64, 128 ... Zatem perepaivaem wire nA + and
delaem samoe too. If something
no tak melkoshemu change.
Second kanal checked analogichno.

 Proverka deshifratora may occur by connecting the entire
deshefriruyuschey chasti to the bus (without
buttons and koordinat), and reading
from the ports of the mouse. When pravilnoy
assembly of the ports 64479, 65503,
64223 should schityvatsya number
255. If it does not tak, then razberites what it was, and 
continue check.


 Nakonets we all assemble in a heap
We consider that the complex would behave
normalno (the mouse does not reconcile okazyvaet harmful 
effects, it should be sledovatelno HOW usually). It is worth 
noting there is experience of some firms (Rotten,

if you can tak vyrazitsya), not
'll pokazyvat paltsem that
whether because of za zhadnosti, whether
because of the stupidity za stavili in tachki 6
megagertsovye percent and razgonyali
of 7 nA megagerts. In rezultate
nA takih tachkah, if you try
hang something nA bus
tachka uhodila in meditatsiyu (GURU
:)). Should zametit it
it was not all polls nA tachkah
this office only a certain nA. Tak that if the vas is
takoy coffin, it can be safely vydrat ottuda percent and change 
it, Well skazhem nA 10 megagertsovuyu

version (percent change over nA
megagertsny not pomeshaet and thus have
who do not. Although better postavit Z80380 nA 33 MHZ;).

 Now kogda all looks like
HOW can usually postavit mysha.
PHASE stick and COUNT have
unto you samim empirically, because
that the probability that unto you
udastsya somewhere to buy a suitable mouse vesma mala. Although
if tak unto you are lucky, you can
and share with me, informatsiey, that are found where the mouse 
8). Podobrat dannye things do not sostavit truda those who 
dochital to This CAREERS. For experiments

would be the best ZF5;).

P.S. to convert pisishnyh mice well suited mikroshema
1561TL2 (I tak kazhetsya).

P.P.S Want zametit that vas
Nobody zastavlyaet nothing delat. Tak that if something does 
not tak, me to reconcile the claims. HOW TO

they say if you really pseudo-legs
and false-handle, nado pokupat
