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.
That's why my original plan for home use was to make a Sun4 keyboard
cable adapter - if it's just me, I can use a newer keyboard/mouse.
