Полигон-2

Pomogite, plz.-nuzhna electricheskaya shema bus mouse dlya Amstrad PC1640!

MaiklsBlack
есть тоже эта машинка , к сожаление без клавы и мыши ....
собираюсь приделать обычную клаву ....
мышка там обычная бас маус схема , в конце недели дам распиновку

1.15.5 Keyboard Connector
The Keyboard connector is a 6-way Din socket. The pin assignment is as follows:
Pin Assignment
1 KBCLK                                              
 
2 KBDATA
3 M1 (Mouse Button 1)
4 GND
5 +5 Volts DC
6 M2 (Mouse Button 2)
The M1 and M2 signals are connected directly to the keyboard controller in order to produce keycodes.
1.16 Mouse Interface
The mouse interface consists of two switch inputs from push buttons and two 8-bit X & Y coordinate counters. The two mouse switches (M1 & M2) are arranged to form part of the keyboard matrix and are handled as keyboard data (producing low level keycodes 7E and 7D respectively).
The Mouse X-Coordinate (I/O Address 078h) is an 8-bit counter which can be read by the CPU. Any write access regardless of the value written to the X-Coordinate location clears the counter. Similarly the Mouse Y-Coordinate (I/O Address 07Ah) can be read by the CPU or cleared by any write access to its I/O address.
The counters are incremented or decremented according to the direction of movement of the mouse, and their values indicate the mouse movement since last read or cleared. The X-Coordinate counter increments for "Right" motion and decrements for "Left" motion. The Y-Coordinate counter increments for "UP" motion and decrements for "Down" motion. In order to properly track mouse motion, software should read and clear the coordinate counters at a rate high enough to prevent overflow from positive values to negative values or negfative values to positive values for a fairly high rate of mouse movement. The scaling of mouse movement is such that one increment of the counter represents 1/8 mm of physical mouse motion.
The delivered operating systems have AMSTRAD specific mouse drivers which actively perform the Read-and-Clear operation (every 18 ms) using the ticker interrupt. This can cause the appearance of no mouse motion to the casual observer sampling the mouse coordinate counters. See Appendix 1 for additional details concerning Mouse Software Interfaces.
1.16.1 Mouse Connector
The mouse connector is a 9 way D type (female) connector located on the left hand side of the case and it has an AMSTRAD specific pinout. Attaching any other manufacturer's hardware (even though the connector may be similar) to the PC1640 mouse connector may cause serious damage to either the main board electronics or to the alternative (mouse) hardware.
The mouse connector pin assignments are as follows:
Pin Assignment
1 XA  
mouse connector
2 XB
3 YA
4 YB
5 Spare
6 M1
7 +5 Volts DC
8 GROUND
9 M2
The first four pins contain optically encoded phase XA, XB, YA and YB square waves. For positive motion the square wave on the A phase leads the B phase by 90 degrees with the reverse being true for negative motion.
The remaining pins carry Mouse Button 1 (M1), 5V power, Ground and Mouse Button 2 (M2) signals.

дрова здесь: http://web.ukonline.co.uk/cliff.lawson/files.htm.Только вот сигналы на входах триггера шмитта (после фотодиодов) будут достаточны для переключения из 0 в 1?

Насчет грызуна - берите схему кемпстон мауса , или УВК ЕС1841.02
это абсолютно подходящие
на счет клавы вы конечно правы что стандартную туда не подцепить и дело вовсе не в разьеме и не в протоколе (там обчный ХТ протокол)
дело в том что сканкоды клавитатуры отличаются от сканкодов ХТ ...
кто знает принцеп работы контроллера клавы в РС тот поймет на каком моменте затык ...
Я собираюсь просто привернуть 6542 на плату пауком , в соотвествии с адресацией этого компа
