Aside from the posts on the side of the
connector, what is unique about the cable and connector? What?s the deal with those posts?
Aside from them, it looks like a 6P4C with only three leads connected.
AFAIK, the posts are there so you don't plug your mouse into a phone
jack or a modem port. There are cutouts on the back of the Sun3
keyboard to admit that connector.
One could almost certainly start with a 6P4C cable and fix up the
mouse end and re-use a Sun4 mouse, but for show/display purposes, it
would be clearly a substitute.
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.
