hardware question

[Gerrit van den Berg]

Hi,   On behalf of Leonardo Padial I want to ask your attention for a question about the pulses of a MSX mouse. Padial has developed a PS2 mouseconnector for the new MMSX, and now he wants to combine several other cards like the keyboardinterface and a PSG+Audio connector in one card. To do this he needs an answer to  the following question:   I want to include the PS2 mouse with the PC keyboard. I have the SW for the mouse in digital data style. What are the pulses in Forward, Back, Left & Right pins 1, 2, 3, & 4 of the MSX analogic mouse? With this info I can finish the analogic emulation (*) and then the new PC Keyboard can include : Mouse Analog/Digital connection, one/two joystick ports and PSG with stereo power amplifier with digital volume and input for Audio CD... (see LPE-PSGM-V1).   (*) signal with moving analogic mouse left. I need to know something like: pin 3 (left):    ____                           |_________? pin 4 (right):    ____                             |_________? pin 1             _____________ ? pin 2             _____________ ?   Can anybody help him with this? Thanks in advance!   Gerrit
