Philip, if you think this will work on your 6150, you
are welcome to try
it. I don;'t have the mouse pad (and as I said it's optical, from the
time when you needed a special mouse pad for optical mice), and it is, of
course, untested..
Maybe if someone comes up with the protocol (or some reference for the
original mouse, like...schematics :oD) I can help in doing something like a
PS-2 converter :)
