  Today I will talk about finalizing the PC-shnoy RS-232 mice 
for use in conjunction with the Kempston Mouse Interface, as 
described in the previous issue of the newspaper. 

  Advance apologize Mad Max'u for the use of materials articles
(C) Mad Max. What if the wrong Bat
type
published in ZX FORMAT # 5. I do not for
commercial advantage, and our general business sake.

  Well, now for the Mouse! I mean, Well, now for the mouse ..

  For the work we need: m / K1561 (561), TL1,
four resistor 5.6 kOhm, three 1 ball and a 150 ohms.

  The mouse can take any, two-or three-button. Personally I 
have a three button mouse CHAMOXA. 

  First things first otpaivaem mouse cable. Here he
you no longer useful.

  Then fed to mice from all parts, except for two
optocouplers, they give us another place ponadobyatsya.Na 
vypayannoy chip set K1561 (561) TL1, first cutting off all the 
printed guides that are appropriate thereto, photodiodes and 
LEDs, optocouplers. K IC optocouplers and Solder items 
according to the diagram below: 

                                             +5 V

                                        ° °

                                    +5 °

                                    +5 °

                                        °


  The scheme photodiodes conventionally shown as rectangles 
with three-pin and LED optocoupler (On the right side of the 
diagram) in the form of two parallel segments, as capacitors, 
with their anodes have be sent up to +5 V. Mouse (two or

three) come unsoldered as follows:


               /

              / ° e-g


                    1k


                  ° +5 B


  If the mouse controller scheme you have already put
resistors are 1 k, then put them here is not necessary.

  Signals a, b, c and d-is the coordinate momenta
obtained using this myshi.Ih need to connect to contacts Xa, 
Xb, Ya and Yb mouse controller, and what signal to any contact 
you have to choose, as advised by Mad Max, an educated bet. I 
advise you to simply analyze the data and have meaningful 
shemki solder these four wire.


  Signals eg (ef) - are signals from three (two) of the mouse 
buttons. 

  Now all you have to unsolder the cable, which consists of
eight conductors for a two-button, or nine
conductors for a three-button mouse: signals ag
(A-f), +5 V and ground.

  Everything. You can safely connect the device to
your computer and enjoy working with this
amazing animal.
