I am using a MiniDIN-8(F) to 6P4C (without those posts) cable I made to
connect a type 4 mouse to my type 3 keyboard.  Works perfectly.  I think
I found the pinouts for type 3 and type 4 mice in the SUN Hardware
Reference?  If anyone has trouble figuring it out I can measure the
connections on my adapter and post them.
