The Sun Hardware Reference (http://www.sunhelp.org/faq/sunref5.html) says:

     Sun-2
     -----

    Optical mice, usually black, from Mouse Systems. They use a special
optical mouse pad with broad stripes. Cable with RJ connector which
connects either to the CPU directly or to an RJ-DB15 adapter (see type-2
keyboards above).

     Sun-3
     -----

    Optical mice, usually white, from Mouse Systems. They use the same
mouse pad as Sun-2 mice. Cable with RJ connector which connects to the
back of a type-3 keyboard.

     Sun-4
     -----

    Optical mice, usually white. They use a special optical mouse pad
with narrow stripes. Cable with DIN-8 connector which connects to a
type-4 or type-5 keyboard.
