I would 2nd that comment concerning PS/2 connectors on Sun equipment.

For the most part, Sun went directly from the Sun 8 pin DIN connector to USB 1.1.

I have (personally) only seen a PS/2 connector on one piece of Sun equipment. 
And more specifically, it was the Sun AXi motherboard.  This motherboard shipped 
with both Sun and PS/2 connectors.   I still own a 300 MHz AXi system.  It was 
the first piece of Sparc gear I purchased for myself (at home) brand new.

If there are more Sun items out there that used a PS/2 connector, I would be 
interested to hear about it.
