My old pc cannot support ps/2 mouse. I can only use serial com mouse. I cut and stripped off an old mouse serial "com" connector cable and wish to join it on the ps/2 connector cable of my new mouse. There are four coloured wires and copper threads on the com connector cable. The colour are black, orange, brown and red. I wonder what are the wires inside the ps/2 cable...are they the same? can i simply join the ps/2 mouse back to the com connector cable? I tried to look for the ps/2 to com connector at shops, but they dun sell it here. Please advise. Thanks.
