Having seen the 8 pin DIN port on the back of the M76, I was 
wondering as to what kind of commonly available mouse could be hacked to 
work with it. I know well that I am going to get flamed by the purists 
here, but one of my missions is to get this VS fully functional on the 
cheap. Must I use a bus mouse? serial mouse? PS/2 mouse? What's the pinout?

P.S.A
