  i people, it is again I-owner DESIRE BBS, then bish Sir DENIS.
Today, as promised, Mr. Systemic adMINIstrator MAN,
ie Minisoft Avec NRJ, I will tell you how to connect the device
type KEMPSTON MOUSE. And so, nachnems:
 First of all, you need a mouse with the controller itself, 
soldering iron, solder, rosin or flux (flux lutchshe course, 
but it is difficult get a bit lower, I will write how to get it 
yourself), stand Soldering Iron, 16-Th wires, and of course 
your favorite SPECCY. Soldering iron should be sharpened by a 
40-45 '(oh, Th is me:), heated to necessary condition, and 
zaludit dipping it in rosin (flux) and solder. Wires so as to 
be zaludit, revealing a pre- their ends by 2-3 mm (with a 
knife, scalpel, forceps, teeth or soldering iron) and then 
perform the operation as with a soldering iron. And so, 
preparations are over, you can start soldering.  Wires must be 
soldered according to the instructions, such as 1-st wire from 
the controller to +5 V with the company, 2 nd GND (ground), 
third on the A7 from CPU (processor feet you can look into 
Zwick # 3) and etc. etc. Well, here you soldered a Bat and he 
has not earned, Well there are such cases, there could be 
neither of which can not be helped, here I can advise you and 
check you are not confused Wire Bat when sewn to the PC (I 
personally own 2-fold and spent re-operation), the second 
reason could be a broken wire , Then can not do food, check out 
all good  and just making sure that she does not live, can bear

her to the nearest morgue or near living resuscitation, there 
your myshe pohorosheet and it can be resurrected.

 But if you connect this beast, and he made the first motion
(Zasemenil paws zavorushil uhami) can rejoice-operation
successful and the rejection of tissue did not happen, not in a 
hurry joy to the end (and that and this), mish may limp fish 
soup may themselves fall. How can there be a reason? But in 
chemv Bat Inside there are two optocouplers, LED and 
phototransistor, diode looks like a transparent and rectangular 
which Gizmo stands in front of the phototransistor - little 
black things with a third findings, and between them is 
spinning roller coordinate X or Y. So Here's one LED can be 
made zamalenkoe voltage , Porobuyte increase it by reducing the 
resistance of the resistor which goes to glyuchaschy LED by 
connecting this resistor parallel to one resistor but little 
value. If this did not help, then look no-rayed if your body

mouse, and if so, then try to lay in the bottom of the hull and
top Cardon, or something else does not transmit light.
If it has not helped or had no skin-rayed, and
cursor continues to twitch, try changing the angle
LED-can help. But if the problem persists
is another option, see what kind of wire from the tail
Bat reaching the controller responsible for the direction you 
want (In which direction the cursor twitches), unsolder them 
and the story there Razak an educated bet (this applies to 
samosrabatyvaniyu mouse buttons).

 After all these operations at the Bat has two states:
    1. You torment her Bat and he went to the ancestors.
    2. Myshak tired to resist and you become completely
       obey.
If you won the item 2. you can congratulate me and fanovat and
rulitsya, but if you won the item 1. then you have to accept
to his fate and take a mish man who could it
resurrect.
 If you do not understand :-( please call me Sir DENIS'u (0152) 
2-60-70 Denis Medvedev, or ask questions, do not DESIRE BBS 
address see above.


MAN> Well, I can only add only a couple of lines from the price

       Stinger'a ...


  Before connecting the controller, check whether enough 
properly you deshifriruesya port kempston-joystick. It should 
not respond to the port # DF, and toko at # 1F, otherwise

joystick will clog these mice. To resolve this
trouble need to disable the joystick on the connector, or
engage in deshidratore kempston'a address A7 = 0-joystick
A7 = 1 - mouse.
 To connect this device to your computer are connected contacts
