The problem is these machines don't have any PS/2 or standard 9 pins
serial ports. They only have 1 15pins port which combines 2 serial ports,
one for the mouse and one for the keyboard.. I guess what I was asking is
wether the electrical signals from a PC mouse are the same as those of a
DEC mouse, so I could just attach the right connector to the PC mouse and
connect it to the DEC...
