I have a few early Sun mice. These all have 3 buttons and a black case. The logo on the
front
is the usual Sun diamond but is more of a blue colour rather than the later purple.
One of the mice (part number 530-0307 Rev A) has the earlier orange Sun logo on the back,
and
is fitted with the DA15 style connector (15 pin).
The other mice although looking similar, have RJ style connectors. They are also stamped
on the back with 'Sun 2'.
Does anyone know if Sun's ever supported 3MBit ethernet?
